Hello!

Thanks for this forum.

I have read and searched a lot on this topic but can not find an answer. My engine light is yellow even though I have changed the lambda, still gives an error code on p223700.

Any ideas?

Thanks in advance!

For the future, Audi has it to solv the problem, seems to be the control unit. (ECU)
