Hi There, I was just enjoying a day I've out this morning and then a light appeared on the dash. It was the coil light which placed the car in limp mode. I stopped the engine hoping to get away with it disappearing but it returned.

 

After the 3rd switch off I continued driving and now I have that coil light and EML light. I placed a basic code reader on which says p403 exhaust recirc issues.

 

Does anybody have any ideas. Please many thanks..

It's related to the function of the EGR valve.     https://obd2pros.com/dtc-codes/p0403/

Thanks schtum. I'll have a look. How wonderful if it was a dodgy connection but alas I doubt I'll be that lucky.

 

Is there much I can do myself or is this a garage job..?

 

Thanks

What is the engine code.

You might be able to fit an EGR simulator/ emulator depending on the engine, then forget about the EGR & any faults it has.

Since you're asking on here, the answer is probably to take it to a garage; preferably a local, independent VAG specialist.  

I've just looked at the egr vacuum solenoid which seemed to make a rattling noise. Bearing in mind the cost and ease of replacing would this be a potential cause.?

I replaced the solenoid and the problem dissapeared completely until today. The code has changed now and isn't an open circuit but just quotes problem with exhaust gas system.
