Is there a definitive list of VW diagnostic codes anywhere? I have read the codes in my Golf and they are follows: 0012c7, 00146B, 00146F and 0023A0. I can't see these codes on any list of VW codes that I can find on the internet. Any ideas?

Yes, but I was asking for a DEFINITIVE list i.e. one that includes the fault codes that I have got.

Someone has suggested that the second fault code is VAG error code 005227, EOBDII Error Code P146B "Diesel Particulate Filter Bank 2 Temperature Rise too low"


Interestingly, or not as the case may be, 146B is 5227 in hexadecimal.:eek:

I've had another go with my scanner and tried another option and I'm getting:

P0401 Exhaust Gas Recirculation Flow Insufficient Detected

P0401 Pend Exhaust Gas Recirculation Flow Insufficient Detected

which looks like a standard VW code. Perhaps if manufacturers bothered to include proper instructions with their products it would make life easier!
