Hello
Hello Everyone. I have a 2003 Audi A4 with a 2.4 V6 petrol engine (BDV). I keep getting the MIL light on and even if I clear it, it will return within a few days of driving.
VCDS has captured the following errors which I would appreciate any assistance on.
Address 01: Engine Labels: Redir Fail!
Part No SW: 8E0 909 552 N HW: 8E0 909 052
Component: 2.4L V6/5V G01 0004
Coding: 0011581
Shop #: WSC 63351 000 00000
VCID: 39725A9373A6FDD69C9-515E
6 Faults Found:
17537 - Fuel Trim; Bank 2 (Mult)
P1129 - 002 - System too Rich - Intermittent
17535 - Fuel Trim; Bank 1 (Mult)
P1127 - 002 - System too Rich - Intermittent
16518 - Oxygen (Lambda) Sensor B1 S1
P0134 - 004 - No Activity - Intermittent
16538 - Oxygen (Lambda) Sensor B2 S1
P0154 - 004 - No Activity - Intermittent
16805 - Warm Up Catalyst; Bank 1
P0421 - 001 - Efficiency Below Threshold - Intermittent - MIL ON
16815 - Warm Up Catalyst; Bank 2
P0431 - 001 - Efficiency Below Threshold - Intermittent - MIL ON
Readiness: 0000 0000
The strange thing is, the car runs and drives fine. After a few days of driving locally, the MIL will come on. If I am driving on the motorway the car runs fine and sometimes the MIL turns off on it's own.
I cannot determine from these codes whether there is an issue with the Lambda sensor and if so which ones, or if there is an issue with fuel trim which I wonder could influence either reading.
Is there an advance setting within VCDS that can help me diagnose this issue further?
Any support would be appreciated, as I do not want to buy new o2 sensors if there is nothing wrong with them and they are reporting an error from something else that is wrong.
Many Thanks
Steve
