M40 Earth (Grounding) Cables

Post Thu Jan 18, 2024 11:37 pm

Hi,

The car is a 01/1990 316i Auto with the M40 engine.

I'm trying to track down an issue regarding my engine. It was suggested I replace the earth (grounding) cables. I found the alternator one from BMW and bought it.

I also know that there is another one between the engine and the frame but ETK is driving me crazy as I cannot locate the part number for that specific one. Would anyone happen to know what the part number is for that?

Also am I missing any other earth (grounding) points/cables that I should look into replacing?

Thank you very much!

I had to replace it some time ago, it was impossible to locate on ETK for the M40 coupe/sedan, but I found it on the touring and it should be the same. I ordered it and replaced with no problem. It's the one that goes from the right side engine mount to the chassis.

Part number 12421737755.
