Best shot is to go online and use the many databases available to determine the part number specific to the engine size/yr etc.

Thank you for your reply. I visited the website but nowhere on the website it tells whether it is Bank 1 sensor2 or not. The error code keeps telling bank 1 sensor 2. Does any know what is the Bosch part number for it, will really appreciate it?

thanks

I had the same problem with finding B2S1 oxygen sensor for my 2003 A6 3.0L FWD.
I did as follows:
- I took a very close look at the electric connector (or number of wires in case you want a general purpose one).
- I search on amazon.com by "oxygen sensor before catalytic converter" and then they have a feature to check compatibility by year/make/model and I purchase the one having the same electric connector.
It worked for me.
