Hi.

My car had an erratic adle when started from cold on a couple of occasions lately.

Took it into Audi and revealed the following fault codes:

P1129 Long term fuel trim mult., Bank 2
System too rich
Sporadic

P1127 Long term fuel trim mult., Bank 1
System too rich
Sporadic

P1557 Turbo/Supercharger Boost Sensor (A) Circuit
Value above ypper control limit
Sporadic

Any ideas what these mean and most likely solution appreciated please.

Get a pressure done , check block 032.. Looks like a boost leak..
