Removing Nissan Qashqai DPF FilterNissan Qashqai DPF Design Problems
The Nissan Qashqai is a great looking car and with a very strong engine. We’ve found the 2.0DCi model is currently manufactured with the DPF (Diesel Particulate Filter) and our main concern is the size of this filter. The filter is installed in the centre box of the exhaust and this in itself is an issue because the further down the exhaust it is, the lower the temperature of the exhaust gasses are before they reach the DPF for a regeneration.

We believe the filter would have been better suited mounted directly on the downpipe but we can see that space was an obvious issue in the design of this vehicle – but then how have other hatchbacks achieved this..?

To learn more about the DPF system, please see our Diesel Particulate Filter (DPF) Problems & Solutions article.

Common Symptoms Of A Failed DPF

  • Loss Of Power / No Throttle Response
  • Glow Plug / Engine Management Light Illuminated On Dash
  • Poor Fuel Consumption
  • Hard To Start & Slow Pick-Up In Speed
  • Limp Mode (Won’t Rev Over 3000RPM)
  • Fault Code: P1435, P1436 & P0611 etc..
  • Engine Starts & Eventually Cuts Out
  • Engine Fails To Start

Once the DPF has failed to regenerate and blocks up on the Nissan Qashqai, the light will not go out without having it reset and Nissan currently charge £250+ Vat for this service whilst carrying out a forced regeneration, however, after doing so it is strongly advised you must carry out an oil & filter change because it will dump fuel in the oil to raise the temperate and this then will cause lack of lubrication and can also lead to over pressurising if you’re not careful.

Why Not Regenerate My Nissan Qashqai Blocked DPF?
Regenerating the DPF if it becomes blocked is not such a bad thing, if it’s the first time you’ve experienced problems but if it has been regenerated once already and the light is back on, then you’re only real options are a new filter or a DPF Removal because regenerating it again will only potentially lower the life expectancy of your injectors and at the same time damage the elements of the already blocked filter so it will block up a lot quicker the next time round.

The DPF (Diesel Particulate Filter) does have a life expectancy just like a timing belt and it is advised to have serviced to avoid it getting blocked and causing other relevant issues such as the following list of problems which we’ve seen on some models:

  • Turbo Damage (Caused by Carbon-Backup)
  • Engine Damage To Seals (Caused by Carbon-Backup)
  • Injectors Damaged (Caused by Carbon-Backup)
  • EGR Blocked Up (Caused by Carbon-Backup)
  • Sensors In Exhaust Damaged (Caused by Excess Heat & Carbon Deposits)
  • Complete Engine Failure (Caused by Carbon-Backup, Excess Back Pressure & Lack Of Lubrication i.e Oil Contamination)

A blocked DPF can quite quickly turn into a very expensive repair if it is not dealt with immediately.

Nissan Qashqai 2.0DCi DPF RemovalIs There Not A Permanent Solution For A Blocked DPF On A Nissan Qashqai?
There is indeed a permanent solution and that is to have the complete DPF system removed and de-activated from the vehicle. This will ensure the vehicle will not lose power, no warning lights (DPF Related) will come up and the vehicle will not attempt to regenerate but best of all, there will be NO DPF on the vehicle meaning nothing to block up and so you can drive the vehicle how YOU want to drive it and not have to worry about doing it any harm.

How Will SINSPEED Remove My Nissan Qashqai DPF?
When your Nissan Qashqai comes into our workshop we start by deleting down the fault codes and downloading the Engine ECU map files to begin manually decoding and de-activating the complete DPF system. We offer a CUSTOM DPF Removal session and do not use any kind of automated softwares in our process, this eliminates the possibility of problems which many people come across after having their DPF removed by mobile tuners.

Whilst the software is being manipulated, we take your vehicle into our workshop to have the filter physically removed from the exhaust system and at the same time carry out a full visual inspection over the vehicle to see if any other faults are occurring just to ensure you peace of mind that after your vehicle leaves our workshop there are no other problems and if there are, we can notify you and quote you accordingly – Yes, we do carry out general mechanical repairs & we’re very cost-effective!

After reprogramming the Engine ECU with the new Custom DPF Removal software, we then proceed with a FREE Smoke-Correction service to ensure the vehicle won’t smoke and it will continue to pass an MOT – This is our guarantee and something that currently NO other company in the UK can offer!

What Is A CUSTOM DPF REMOVAL Session?
By Custom we mean after downloading the map files and decrypting them from the Engine ECU, we manually scan through the 1000’s of data strings to locate and delete all locations of the DPF map files, however, some data strings for the DPF are interlinked with other sensors on the emissions circuit such as the Lambda Sensor, Temperature Sensor, Air Mass Sensor & Exhaust Gas Pressure Sensor. Deleting these data strings will disrupt the sensors and possibly stop them from working which would also throw out the vehicle emissions and could potentially cause a lot of problems if not immediately then over time.

What we do is modify all interlinked data strings to ensure that the DPF map settings are completely removed and the sensor map files are recalibrated to work optimally even without having a DPF installed on the vehicle – This ensures it will not disrupt emissions and again guarantee the vehicle will continue to pass its’ MOT.

Nissan Qashqai 2.0DCi DPF Blocked ProblemsHow Is This Method Different To Other Companies?
Many companies and mobile tuners are found to be using “Automated Software” and by doing so, they do not manually delete and modify data strings – instead, what they do is download the map files and run it through a piece of software which attempts to automatically locate the DPF data strings and delete them but by doing so they will either purposely skip the interlinked data strings so not to cause immediate errors (this means vehicle will continue to regenerate causing damage to injectors and bore wash pistons over time) or the software will accidentally delete the interlinked data strings and corrupt the map files for the emissions related sensors causing many problems.

What Can I Expect After My DPF Is Removed?

  • Increase In Power
  • Increase In Performance
  • Better Fuel Economy
  • Smoothed Out Flat Spots In Rev Range
  • No More Limp Mode
  • No More Fault Codes
  • No More Warning Lights
  • No More Regeneration
  • GUARANTEED MOT PASS!

After having the DPF removed from your Vehicle, it will not bring up any error messages and the car will not go into LIMP mode. Also, you will never experience any Regeneration messages where the ECU normally attempts to clean the DPF – this is because the DPF is no longer existing.

Finally, you will experience an overall increase in performance, smoothing out any flat spots and safeguard the life of both your engine & turbocharger.

A new DPF (Diesel Particulate Filter) will range from £700.00 – £1500.00 (+Labour & VAT). We can remove the entire DPF for a fraction of this cost and you’ll never have to worry about it ever again.

  • My DPF light and MI is on 2ce in a month and the dealer is asking me now to pay for a new DPF. I use Nissan Qashqai Acenta 2.0 diesel (2007), Do you give guarantee for what you do>

    Thanks

    • Hi Josephine,

      Yes, we offer a lifetime warranty on our DPF Removals. We had a Nissan Qashqai come in to us earlier in the week, on average we’re seeing 1-2 a week so they are quite common and the DPF Removal is very effective and will give great benefits – Better Performance, Increased Fuel Economy, More Power and a sharper throttle response. It will also increase the life expectancy of the turbo and engine.

  • HI IM LOOKING INTO GETTING MT DPF ROMOVED BUT JUST CAME ACROSS A TREAD THAT IF YOU HAVE IT REMOVED AND YOUR CAR GOES IN FOR A MOT TEST THAT IT WILL FAIL THE MOT DUE TO THE DPF BEEN REMOVED!!
    CAN YOU CONFIRM IF THIS IS TRUE.

    REGARDS DEAN

    • Hi Dean

      Please see our main DPF Removal article for information on this. From February there will be a visual inspection of the DPF at MOT’s and if they can visually see the DPF is missing, you will fail the MOT. Although our DPF Removal service is very discreet and cannot be visually picked up on, we offer all our DPF Removal services as an off-road use service.

      Kind Regards
