My engine management light has come on.
Audi have carried out diagnostic and found fault code p200200.
They want to replace EGR and regen the PCF for £1550 which is money I haven’t got.
is it worth just getting the PCF cleaned first and see if clears the fault? Or should I go all in from the start?
ideas welcomed
