Hi All, I have just put an ADY in my VW T3 (T25) truck. We are getting a lambda error 00537 through VCDS Lite. We have tried two MAFs and two lambda probes but still have the issue. Question - will a leaky exhaust after the lambda / cat cause this or is it more likely to be in the intake side of things? From the manifold to the lambda there are no leaks, we do have a couple of leaks after the cat. The wiring from the ECU to the lambda is as is from VW. There are no other error messages in VCDS. We are scratching our heads here. Cheers Titus Leipzig, Germany.
Okay we fix the problem by correctly plumbing in the carbon filter. It was all down to an extreme level of buffonary on my behalf.
