Scanned the car today briefly with VCDS Lite, but I think my KKL lead is goosed. Been tempramental for some time now.
Anyway the codes are:
16518 P0134: O2 Sensor Circ.,Bank1-Sensor1 No Activity Detected
16538 P0154: O2 Sensor Circ.,Bank2-Sensor1 No Activity Detected
17967 P1559: Idle Speed Contr.Throttle Pos. Adaptation Malfunction
17973 P1565: Idle Speed Control Throttle Position lower limit not attained
So the dose of Cataclean only works for 2.5k miles!
So I need to replace both Lambdas.
How to solve the other two?
Some of you may remember, a short while ago, I posted about poor MPG. It was around the 25 mark. Now, the car will do an average of 30.9MPG (according to the DIS) on a journey to and from work. Would this improvement be of any effect from the lambda's failing?
