Hello, I have a 2005 e53 and wondering about air suspension pump differences. Is there more than one standard suspension pump?

The original from my car:



And one I bought off ebay:



The mounting holes are same but some differences in wiring which the mechanic does not want to take responsibility for. I have ordered good parts from this ebay site before but may have to send it back if its not compatible: http://www.ebay.com/itm/292081699945?_t ... 2749.l2649

Any advice appreciated. Thanks!

Depends upon whether you have self-levelling suspension (rear only) or full air suspension (all corners).  The lower pic looks like one that is for full air?

Checked Realoem and that part number is for 2-axle air suspension, not self-levelling.

Thanks. Wasnt aware of the difference in suspensions. According to my VIN, I have the "S221 2-axle self-levelling suspension" option. Ebay seller acknowledged the error and will take it back. Expecting a new one soon.

Cheers.
