You have to scroll down and choose FREE download... that is the way they use it... I had no other way, I do not have a place where to upload the files :-(

Any ideas? Is Lambdasensor gone?

What should I check and where (using VAG-COM) to detect that?

PLS HELP

Thank you

Radu

Clean the throttle valve and reset the throttle chamber and the problem should be gone

rvacaru, please let us know if that fixes you problem, and thanks for the advice, Netnavi.

I have already cleaned using a good spray the Throttle valve...

I suspect oxygen sensor... I have VAG-COM logs... voltage is not variable between 0.2-0.8V, but ONLY around 0.438 V !

Radu

Nobody that looked to my logs is able to tell me if my oxygen sensor is gone?

:((

Today the Engine light came again on, same error :(

Problem fixed.

Timing belt was mounted wrong...wrong timing... done by Skoda Service....
