Hi Gents,

Had the engine light pop up on the way home today. Ran VAG-COM across it and found these two codes.

2 Faults Found:
17535 - Fuel Trim: Bank 1 (Mult): System too Rich
P1127 - 35-00 - -
17537 - Fuel Trim: Bank 2 (Mult): System too Rich
P1129 - 35-00 - -
Readiness: 0000 0000

I've cleared the codes but wondering what it could be. Recently (4K miles ago) had the MAFF, N75, 710N and Lamda's changed by Unit20, so I'm not expecting it to be any of those.

Regards,

John

I know this is an old post but did you find a solution to this?? I have the same fault codes stored. Didn't put the light on though.

Sounds like a/several boost leak(s) to me.

Makes sense. If air that has been metered is escaping somewhere. What about MAF a problem?

Failing MAFs usually throw the opposite codes, "mixture too lean"
