Seat 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.
