Audi Exhaust Gas Recirculation Valve EGR Delete Service

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. This will ensure that no fault codes or warning lights appear at all, and will stop the vehicle from going into limp mode.
