vag com

[swalk999]

i bought a version of vagcom from ebay and it told me that I had a faulty lambda sensor which was replaced but car is still lumpy ..
put it back on vag com and it says i still have lambda sensor fault .. 00537 & 00533

when i reset the codes minutes later they return HELP

The 00533 is the idle control valve, and the 00537 is more to do with lambda control system, if lambda is defective you would have:

Oxygen Sensor:
No Signal

I think maybe some golfs are preheated sensors and are relay controlled, perhaps this can be your problem
