Question

I have the engine code P0030 on my Audi, where is the sensor located?

Answer 1

HI there

This is the first sensor on bank 1 of the engine. Without the engine size, it's difficult to tell you which side of the engine that is, but it is the first O2 sensor BEFORE the catalytic converter that needs to be replaced in most cases.
