Where is this located?
Can someone please tell me where this relay is located in my car? I've looked in my trunk and under my hood but I cannot find one that is brown and has three prongs 
Have a 99 C43 with 01 E55 swap.

I believe this is the secondary air pump relay... no? I'm getting a P0410 error code and read this relay might be bad.

Wow can't remember if I ever had that code, but if I did, which i can't remember, I think I did the EGR valve / tube cleaning. Not sure about that. I looked it up for the 55 models, post 2000 and they apply to the C55, CLK55, E55, etc. there is a relay for it, but i dont think on the w202 had one.

Does the C43 have a Secondary Air Injection Relay?
