VCDS method of finding oxygen/lambda fault?

[briang9]

just been searching and found this post, has anyone found a successful solution to this? I have sports cats which seems to cause the Engine Management light to come on had it checked and its related to post cat sensors, I know the Laird got some extensions fitted to his but as its now Davids car and he had the same problem last weekend doesnt look like that worked long term either.

thanks for any help

cheers

Software needs to be modified in similar manner like remapping. It needs to be read from ECU, modified and written back. A8 Doc or Mkoneman should be able to help.
