Hey all, I am replacing my Airmatic compressor today and was wondering which relay in the engine bay fuse department is for Airmatic? Picture attached. I tried the paper fuse diagram in the spare tire well, but it only showed fuses and not relays

2011 GL550 Engine Compartment Fuse Box

For those of you who replaced the air compressor with "Mercedes Suspension Air Compressor - Arnott 1643201204" it came with an aftermarket relay, along with instructions saying it should be installed. However, after reading other forums about bad air compressor relays, should I stick with the OEM Hella relay or the relay Arnott had supplied with?

Picture attached.

Hi

It’s #3. I would use the Arnott one as it is bound to be newer than what’s in there anyways.
