Does anyone have a way to identify the electrical relays in the engine/ right rear trunk section of a 2008 ML 350? I have the fuse chart identification chart. THANKS!!!

Specifically, the relay for the Airmatic air suspension. My ML 350 came with the P3 package. I have read that there may be a problem with the compressor relay and that the Hella unit is a much better relay. I want to locate this relay and check what relay is currently on the car so I know if I should change it. I believe the new Hella relay is #002 542 7219. I understand that the old relay may cause the compressor pump to run longer than needed and eventually burn out the compressor. This is from a MBZ service campaign #2008080001. Thanks for all your help!!!!
