Title: MK4 GTI 2.0L fault codes
Post by: Rmachines on 16 April 2012, 20:10

Evening,  My sister is down on holiday with her MK4,  with complaints of bad economy and MIL Light!

Did a fault code scan  - 
16518 - Oxygen (Lambda) Sensor B1 S1: No Activity
        P0134 - 35-10 - - - Intermittent
17536 - Fuel Trim; Bank 1 (Mult): System too Lean
        P1128 - 35-00 - -
16555 - Fuel Trim; Bank 1: System Too Lean
        P0171 - 35-00 - -
16523 - Oxygen (Lambda) Sensor B1 S2: Response too Slow
        P0139 - 35-10 - - - Intermittent

Im inclined to replace Number 1 sensor,  assuming the other faults are caused by this, im not sure about the last fault though.

Any other ideas than number 1 02 sensor here?   Cheers.  :smiley:

Incase anyone wonders - Yes it was the number 1 02 sensor.
