Secondary air pump part number

Need to replace my secondary air pump and wondering if anyone has the Mercedes part number for this? I didn't see an obvious label on the pump itself (didn't take it out yet).

Thanks!

The Bosch part number is 0 580 000 021 816 and the MB part number is A 000 140 43 85

here's a nice read before you replace it ...

Re: Secondary air pump part number

Alright, to add to the confusion - I replaced the pump with one from a salvage yard, and I can still feel air coming from the pump when the car starts and the pump runs initially, and ONLY when the pump is running. I looked over the hose that connects to the pump and I don't see any cracks or holes.

Does anyone else feel air coming from the front of the secondary air pump when it runs?
