A few exhaust questions.....

Hi Everyone

I tried to search on the forum for answers but failed.

I currently have a faulty O2 sensor on Bank 2. It states that the S1 sensor needs replacing.

Here follows my questions that need answering.
1. Which side are Bank 2 located on our cars? (Just take into account that my car are RHD)
2. What are the part numbers of the sensors?

Waiting in anticipation for answers.

Regards

I'm not sure the S1 sensor is for front or behind catalyst.

You can search some parts website for RS4 B7.
Bank 1 = passenger or right side
Bank 2 = driver side or left side.

So your car is RHD, is left side (Passenger Side).

I have got more information for you and anyone needs it.

Bank 1 O2 sensor
Front : 1K0998262AA (original no. 079906262B)
Rear : 022906262BM

Bank 2 O2 sensor
Front : 1K0998262AA (original no. 079906262A)
Rear : 022906262BQ

Some parts website have good detail to studying. ^_^

Hope can help you.
