Seat Exhaust Gas Recirculation Valve EGR Removal / Delete Service

Seat EGR Valve RemovalsSeat EGR Valve Faults & Problems
Modern Seat’s are fitted with EGR valves which are integrated into the exhaust valve to allow gasses to recirculate back into the engine to be re-burnt before being released into the atmosphere to help reduce vehicle emissions. This process, however, leads to the eventual build-up of carbon in the inlet manifold and engine, as well as the engine valves causing the loss of power and a drop in fuel economy of the vehicle.

This used to be an easily resolvable issue on older Seat’s, however with new sophisticated systems being installed on newer models, it has become more challenging to rectify any EGR problems. This is due to the fact that warning lights and fault codes now appear when trying to blank off or bypass the EGR, sometimes even causing the vehicle to go into “Limp Mode”.

Seat EGR Valve Common Faults
Some of the most common problems with the EGR valve can become extremely expensive to repair if not looked after, especially if you are looking to replace it completely. If this is the case, it is always advised that you have the EGR Valve thoroughly cleaned with every other service to maintain it. Another option available for a faulty EGR valve is to have it deleted from the ECU completely so it is programmed to stay shut at all times. This will eliminate any issues regarding warning lights or fault codes coming up and will also stop it from going into limp mode and losing power.

Some of the most common faults to look out for include:

  • Missfire
  • Loss of Power
  • EGR Flap Position Sensor Faults
  • Smoke on Acceleration
  • Fluttering On Acceleration

This is not a complete list, only a selection of the most common problems that customers advise of when calling to enquire about our EGR options.

Vauxhall / Opel Exhaust Gas recirculation Valve EGR Delete Service

Vauxhall Opel EGR Valve RemovalVauxhall / Opel EGR Valve Faults & Problems
Many modern Vauxhall / Opel vehicles have an EGR valve fitted to them which is a device designed to lower harmful emissions being released into the atmosphere. This is done by recirculating gasses back into the engine to be re-burnt, but during this process, carbon build-up in the inlet manifold and engine is a side effect that causes many problems, including the loss of power as well as a noticeable drop in the overall economy of the vehicle.

A blocked EGR Valve used to be a lot easier to repair on older models, however, with newer systems in place it has become more difficult to carry out an EGR delete. This is due to the systems being able to identify when an EGR has been bypassed / blanked off, which cause fault codes and warning lights to appear, and in some cases, causing the vehicle to go into “Limp Mode” which causes a decrease in power.

Vauxhall / Opel EGR Valve Common Issues
Some of the most common problems you will come across when the EGR is blocked on your vehicle are:

  • Smoke on Acceleration
  • Loss of Power
  • Missfire
  • Fluttering On Acceleration
  • EGR Flap Position Sensor Faults

If any of the above faults sound familiar, you will be generally be advised to get your EGR replaced. This is an option that can work out to be quite costly, especially as it is also recommended that you get the EGR cleaned thoroughly with every other service to maintain it and prevent any further carbon build up. The other option would be to have the EGR Delete service which involves programming the ECU to tell the EGR Valve to remain shut at all times. This then ensures that no warning lights or fault codes appear at all, and thus stopping the vehicle from going into limp mode.

Vauxhall Opel Blocked EGR ValveVauxhall / Opel EGR Delete Service By Sinspeed
Here at Sinspeed, we offer a completely safe and bespoke EGR Delete Service which involves us deactivating the EGR valve system from the ECU to remain shut at all times. We log on to the vehicles on-board engine management system and then from there we program the EGR valve to remain off so that gasses no longer re-circulate into the engine and stopping any further blockages.

Below we have compiled a short list of the Vauxhall / Opel models that we offer an EGR Deactivation service for. If you cannot find your vehicle on the list, please do not hesitate to contact us on 0203 815 9441 where we will be able to check for you.

DPF Blocked Regeneration Warning Light

Audi DPF Removal Service

DPF Blocked Regeneration Warning LightHave you noticed that your DPF warning light is on? Or is your Audi suffering from loss of power? If so, this could be due to a blocked Diesel Particulate Filter which is no longer functioning efficiently!

A DPF is integrated into the exhaust of most modern diesel Audi’s from 2005 onwards, to trap and remove Diesel Particulate Matter or soot from the diesel exhaust gasses to ensure that the residue smoke is cleaner before being released into the atmosphere. The aim of this process is to remove up to 80% of diesel particulate emissions, however, as the DPF burns off this soot via regeneration, it leaves an ash residue in the DPF which cannot be burnt off, which eventually causes it to become blocked. This means the regeneration process of the filter cleaning itself can no longer be carried out.

Other reasons for premature blockage of the DPF filter can include the use of incorrect engine oil, lower quality fuels, faulty exhaust sensors, faulty components on the vehicle which may increase soot levels in the exhaust gasses and not having the required driving style to frequently regenerate the filter successfully.

When this occurs, it goes on to create further problems as mentioned above like power loss and the pressure begins to build up in the exhaust due to the trapped gasses, which will go on to try and escape from the next weakest point i.e. the turbocharger seals or the EGR valve, which is where the damage to other components start to occur if not dealt with.

DPF Filter System RemovalsSymptoms Of A Blocked DPF On My Audi
In order for a DPF to run efficiently, the regeneration process needs to be carried out in optimum conditions which occur normally when driving on the motorway at 40-50mph for approximately 15-20 miles. However, if you live in a city which requires a lot more stops and starts, this can cause the DPF to become blocked up a lot quicker.

Some of the signs of a blocked DPF filter are listed below with a list of the most common fault codes found on Audi’s:

  • DPF Warning Light On
  • Limp Mode / Loss Of Power
  • Engine Management Light On (EML / MIL)
  • Glow Plug Light Flashing
  • Poor Fuel Consumption

BMW530D (E60)3.0DDiesel
BMW520D (E61)2.0DDiesel
BMW530D (E61)3.0DDiesel

If you have any of the problems mentioned above with your Audi, it is more than likely that it is due to a DPF failure, and in some cases, you may even find that your vehicle becomes completely immobile due to excess blockage and build-up of exhaust backpressure. When these issues arise, if it is not dealt with in time, further problems may arise such as:

  • Injector faults
  • EGR Faults
  • Engine Faults
  • Turbocharger Faults
  • Oil Contamination

Some of the faults listed can cost in the region of £1000+ to repair if the DPF fault is not dealt with as soon as possible. Some customers have come to us in the past informing us that garages have advised its more cost-effective to just get rid of the vehicle as certain repairs cost more than the actual vehicle itself! Therefore, we always advise that DPF faults are dealt with as soon as possible to prevent any further damage to your vehicle.

My Audi Has A Blocked DPF – How Can Sinspeed Help?
There are several options available to you if you find that your Audi has a blocked DPF:

  • DPF Replacement Filters – You have the option to replace the DPF Filter, however, genuine filters are extremely expensive and only come with a 12-month warranty, which does not cover you if it gets blocked up again unless it is due to a defective filter unit. Cheap copy filters may be another option but these are known to block up very quickly and are not recommended.
  • Sinspeed Complete DPF Removal Session – Here at Sinspeed, we offer a complete bespoke 4 Stage DPF Removal Service where we physically remove the filter from the exhaust system and also deactivate the complete DPF system from the vehicle ECU. By doing this, the Regeneration process is also cancelled out, and we then go on to carry out a full smoke-correction service which is bespoke to Sinspeed, providing you with the most extensive and complete service nationwide. Finally, all Sinspeed DPF Removal Sessions come with a Lifetime Warranty for complete peace of mind.

Benefits of a Sinspeed DPF Removal Session
If you have opted for the full Sinspeed DPF Removal Session you will notice an increase in power and performance straight away, as well as sharper throttle response!

Alfa Romeo DPF Removal Service

Alfa Romeo DPF Filter RemovalAlfa Romeo DPF Problems + Our Permanent DPF Solution
Many Alfa Romeo’s are equipped with Diesel Particulate Filters (DPF) which are integrated into the exhaust systems of newer vehicles to trap and remove Diesel Particulate Matter or Soot from diesel exhaust gasses. When the engine burns diesel, the residue is smoke and in the smoke, there are tiny particles of soot and ash which the filter traps. When it is blocked with soot and ash, regeneration is the procedure of cleaning itself. For a regeneration to work you have to drive along a motorway at 40-50mph for around 15-20 miles – how long it takes can depend on how blocked the filter is.

The aim of this process is to remove 80% of diesel particulate soot (emissions), however, over time, this becomes inefficient and problematic as the filter blocks up and cannot clean itself via regeneration. You will then experience power losses as the pressure builds up in the exhaust by the trapped gasses as they try to escape from the next weakest point i.e the turbocharger seals or EGR valve.

Symptoms Of A blocked DPF On My Alfa Romeo
If your Alfa Romeo comes with a DPF system in place, and you live in a city like London for example, it is more likely for your filter to get blocked up quicker, due to the constant stop & starts.

Below is a list of the most common initial symptoms of a Blocked DPF Filter with a table of the most common fault codes:

  • DPF Warning Light On
  • Limp Mode / Loss Of Power
  • Engine Management Light On (EML / MIL)

The issues mentioned above would suggest a DPF failure and in some cases, the vehicle can become completely immobile due to excess blockage and build up of exhaust back pressure. If not dealt with when the initial faults start coming up, it can go on to cause further problems such as:

  • Injector Faults
  • EGR Faults
  • Engine Faults
  • Turbocharger Faults
  • Oil Contamination

These faults can go on to cost in the region of £1000+ to repair, which sometimes make it more cost effective to get rid of the vehicle due to the overall cost of repairs, therefore, it is always recommended to deal with the problem as soon as it appears to prevent any further damage to your vehicle.

My Alfa Romeo Has a Blocked DPF – What Are My Options?
If you find that your Alfa Romeo has any of the above faults, you have 2 immediate options:

  • DPF Replacement Filters – Cheap copy filters are known to block up very quickly and genuine replacements are extremely expensive and only come with a 12-month warranty, which does not cover you if the filter blocks up unless you can prove the blockage is due to a defective filter unit.
  • Sinspeed Complete DPF Removal Session – We offer a completely bespoke 4 Stage DPF Removal Service which involves the physical removal of the filter from the exhaust system, whilst also deactivating the complete DPF system from the vehicle ECU.

Ford Fiesta 1.4 Clutch Actuator + Gear Actuator Repairs

Ford Fiesta Actuator FaultsHave you found that your Ford Fiesta 1.4 keeps getting stuck in gear when driving? Or does the gear fail to display on your dash? If this sounds familiar, this could be due to a failed Gear + Clutch Actuator.

The Ford Fiesta 1.4 is fitted with an automated manual gearbox which allows the user to interchange between either manual or automatic at the flick of a button, which is not normally the case with any other 5 or 6 speed automatics. As the gearbox operates using sensors and ECU’s, the clutch pedal is not required.

There are three main components that are used within this type of gearbox which includes the clutch actuator assembly, a gear shift actuator assembly and a gearbox ECU. Each actuator is then equipped with position sensors that allow signals to be sent back to the gearbox ECU informing it of what gear the vehicle is in as well as the position of the clutch. The gearbox ECU then uses this information along with the vehicle’s speed and other parameters to calculate which gear is required, when the next gear should change and when to engage / dis-engage the clutch.

Ford Fiesta Common Clutch & Gear Actuator Problems
The most common signs associated with a faulty clutch or gear actuator on a Ford Fiesta 1.4 are listed below:

  • Slips Out of Gears
  • Gets Stuck In a Gear
  • Fails to Select Gears
  • P0810, P1607, P1735, P1732, P1600 & P1608 Fault Codes
  • Gear Display Light Fails

The list above is just some of the common issues that have been diagnosed in our workshop and is not an extensive list.

If you find any of the above faults with your vehicle, it is more than likely that your clutch or gear actuator has failed, if not both. Main dealers will usually recommend that you replace your whole unit, and can cost in the region of £700 + VAT, but the cost will usually increase as each actuator will need re-coding to the vehicle. This will normally only come with a 12-month warranty.

My Ford Fiesta 1.4 Actuator is Faulty – How Can SINSPEED Help me?

Here at Sinspeed, we have the facilities to fully test and repair the Ford Fiesta Gear and Clutch Actuators. We fully bench test the actuators before repairing them, using only genuine OEM parts to ensure that each and every repaired Ford Fiesta Actuator is to the highest standard and meets and exceeds OE expectations. Not only this, but they will not require re-coding when fitting back to your vehicle and will come with a Lifetime Warranty!

Audi EGR Valve Faults & Problems

The EGR valve fitted to most modern Audi’s is known to have many issues. The EGR valve created to allow exhaust gasses to recirculate in the engine. So that they can be re-burnt before being released into the atmosphere, which helps with reducing vehicle emissions. However, eventually, this can lead to carbon build-up in the inlet manifold and engine. As well as the engine valves which can go on to cause many problems. Including a loss of power and a considerable drop in the overall economy of the vehicle.

To rectify the problem of a blocked EGR Valve used to be much easier on older models. However, it has become a lot more complex on newer models due to the more sophisticated systems that are in place. These systems are able to identify when the EGR has been bypassed or blanked off. Causing fault codes, warning lights to appear or even the vehicle to go into “Limp Mode”.

Audi EGR Valve Common Problems

Below you will find a list of the most common issues that are experienced with a blocked or failed EGR valve:

  • EGR Flap Position Sensor Faults
  • Smoke on Acceleration
  • Loss of Power
  • Missfire
  • Fluttering On Acceleration

Your neighbourhood garage will advise you to get the EGR valve replaced if you are experiencing any of the aforementioned issues. Replacing it can work out be very costly, and when doing so, it is also advised to have the valve thoroughly cleaned with every other service to avoid further carbon build-up. Another option would involve just deleting the EGR Valve from the ECU so it is programmed to stay shut at all times.

Mercedes Exhaust Gas Recirculation Valve / EGR Delete Service

Mercedes Blocked EGR ValveMercedes EGR Faults + Issues
Do you find that your Mercedes is losing power when driving on motorways? Or have you found that it is occasionally misfiring? If so, this could be an indication of a blocked EGR Valve. An EGR valve was incorporated into the vehicle’s exhaust system to allow gasses to be recirculated a second time into the engine, to reduce the emissions in the exhaust gasses before they exit into the atmosphere. Although this helps reduce vehicle emissions, it eventually also causes a decrease in the power output of the engine due to the carbon build-up in the inlet manifold and engine.

Diesel Mercedes are common for their EGR failures, and while there were much easier to bypass on older models, newer models have been programmed to identify when the EGR has been blanked off / bypassed by bringing up fault codes, warning lights and even causing the vehicle to go into “Limp Mode” to restrict the performance of the vehicle.

Common symptoms of a failing Mercedes EGR Valve
The common indicators of a failing or blocked Mercedes EGR valve are highlighted below:

  • Missfire
  • Loss of Power
  • Smoke on Acceleration
  • Fluttering On Acceleration
  • EGR Flap Position Sensor Faults

If you find any of the above issues with your vehicle, it is more than likely that the EGR valve needs to be either replaced or cleaned. Replacing it can be an expensive option, as when the exhaust gasses are constantly recirculated into the engine, it can still cause the valve to get sticky with carbon build-up. Therefore, if you are looking at replacing your EGR valve as an option, it is recommended that it is cleaned out thoroughly with every other service to ensure that it is maintained.

An alternative option is to have the EGR valve deleted from the engine ECU, by programming it to stay shut at all times. This is done by blanking it off to ensure that it does not recirculate the gasses back into the inlet manifold/engine, hence ensuring that there are no Limp Mode problems as well as any fault codes and warning lights.

Mercedes CLS Electronic Turbo Actuator Repairs

Mercedes Turbo Actuator RepairsMercedes CLS Electronic Turbo Actuator Problems
Are you experiencing a loss of power in your Mercedes CLS? Have you been told you need a new turbocharger and have a repair bill in excess of £1500? One of the most common failures on the Mercedes CLS from 2004 – 2010 is the Electronic Turbo Actuator. The electronic turbo actuator (wastegate) is controlled by the engine ECU and has a rod connecting to the turbo vanes which is designed to regulate the flow of boost pressure from the turbocharger.

Below we’ve put together a shortlist of part numbers for the electronic turbo actuator:

When the electronic turbo actuator becomes faulty, you may experience loss of power, warning lights appearing on your dash, juddering on acceleration or a combination of faults depending on how the actuator has failed and whether the turbo vanes were open or closed when the actuator failed. Some of the most common symptoms we’ve seen from a failed turbo actuator on the Mercedes CLS include:

  • Loss of power under acceleration
  • Intermittent loss of power under acceleration
  • Smoking on acceleration
  • Fault codes pointing to turbo actuator
  • Fault Code: 2510 – Boost Pressure Control
  • Actuator arm not moving
  • Engine light on
  • Limp mode

Mercedes Turbo Actuator FaultsIf your local dealer has diagnosed a faulty turbo actuator, you will be quoted for a complete new turbo + actuator unit costing over £1500 to replace because the actuator itself is not a part that can be purchased separately. The alternative option would be to have Sinspeed remanufacture your actuator unit for much less and the remanufactured unit would be returned to you with a Lifetime warranty ready to fit.

Mercedes CLS Turbo Actuator Repairs – By Sinspeed
We have the facilities to fully bench test and rebuild the electronic turbo actuator and by using new genuine OEM components as well as uprating components that are known common weaknesses, we can ensure that each and every rebuilt turbo actuator meets & exceeds OE specifications.

Citroen Exhaust Gas Recirculation Valve / EGR Delete Service

Citroen EGR Valve Delete ServiceCitroen EGR Valve Faults + Problems
Does your Citroen smoke on acceleration? Or do you find your Citroen loses power whilst driving on the motorway? These are just some of the indications that your EGR Valve may be blocked. The EGR valve was created to allow exhaust gasses to recirculate into the engine, in order for them to be re-burnt before being released into the atmosphere. In essence, this is ideal as it reduces vehicle emissions, however, eventually, it can start causing issues. As mentioned above, due to the build-up of carbon in the inlet manifold and engine, as well as around the engine valves, causes a decrease in the power output of the engine and smoking issues.

EGR valve failures are known to be very common on Diesel Citroen’s. They were much easier to bypass on older models, however, newer models are equipped with more sophisticated systems where the engine ECU’s are programmed to be able to tell when the EGR has been bypassed/blanked off, bringing up fault codes, warning lights and even causing the vehicle to go into ‘Limp Mode’ to restrict the performance.

Common problems of a failing Citroen EGR Valve
If your Citroen is suffering any of the issues listed below, they could be indicating that your EGR valve has either failed or is blocked:

  • Smoke on Acceleration
  • Loss of Power
  • Missfire
  • Fluttering On Acceleration
  • EGR Flap Position Sensor Faults

The obvious option with a failing EGR valve would be to replace it, however, this can work out to be very expensive and may not even completely fix the problem in the long term. As the exhaust gasses are constantly recirculated, it is inevitable that over time, the valve will get sticky due to carbon build up, going on to cause problems. Therefore, if replacing the EGR valve for a new unit, it is recommended that it is removed and cleaned thoroughly with every other service to ensure it is maintained.

The other option would be to delete the EGR valve from the engine ECU by programming it to stay shut at all times, and by blanking it off, it ensures that it does not recirculate exhaust gasses into the inlet / engine. If the EGR is programmed to remain shut at all times, it will stop any fault codes and warning lights appearing, as well as any ‘Limp Mode’ problems.

By logging into the vehicle’s on-board engine management system via the ECU, we are able to switch off the EGR valve to ensure it stays off at all times. This then means that the gasses will no longer recirculate into the engine and therefore, will stop it from clogging up. When done correctly, it will also ensure that no fault codes or warning lights appear, as well as no power loss.

Below we have compiled a list of Citroen’s we currently offer the EGR delete service for. If your vehicle is not listed below, please contact us on 0203 815 9441 to confirm if it is one we can offer an EGR delete for.

Mercedes CLK Electronic Turbo Actuator Repairs

Mercedes Turbo Actuator RepairsMercedes CLK Electronic Turbo Actuator Problems
The Mercedes CLK from 2002 to 2009 is fitted with an electronic turbo actuator. They are extremely common failing parts and when they do fail, they can become a very costly part to replace. The electronic turbo actuator is controlled by the engine ECU and is designed to regulate the boost pressure from the turbocharger.

Some of the most common problems relating to a failed turbo actuator can include a loss of power and engine warning lights appearing on the dash. See the most common symptoms listed below:

  • Loss of power under acceleration
  • Intermittent loss of power under acceleration
  • Smoking on acceleration
  • Fault codes pointing to turbo actuator
  • Fault Code: 0046 – Control Circuit Performance
  • Actuator arm not moving
  • Engine light on
  • Limp mode

There are a few variations of the actuator fitted to this vehicle, all of which we can test and repair but below are some of the most common part numbers we’ve seen:

Mercedes Turbo Actuator FaultsIf your electronic turbo actuator has failed then your local dealer will be quoting on a very expensive replacement turbocharger + actuator together because the actuator is not a part that can be purchased separately. For this reason, you can expect a repair bill upwards of £1500 for the replacement part. The alternative solution would be to have your actuator repaired by us.
