I'm replacing my secondary air pump and was wondering if this part is shared with other BMW models or is the E39 pump specific to our cars. I found one for a good price out of an E46 but want to make sure it will work for me.

Is in the E39 535i,540i and M5 the same part.

You can plug in a part number and it will tell you all the models that use the same part.
