Hello,

I'm new to the forum.

My 1989 300E oil light goes on an off intermittently while driving. Anything I could do to fix this issue?

Could it be simply a false alarm?

 

I guess I should have mentioned already checked. First thing I checked obviously. The oil golden and 90% full.

 

Check the wire connection to your oil pressure sensor, usually located near oil filter.

 

disconnect sensor wire, clean contacts , coat with die-electric grease, reconnect, ensure connection is tight (squeeze with pliers) also follow wire back look for insolation worn or missing (repair.

 

Hello,

Thanks for all the tips. Turns out that the oil itself was not a good grade or perhaps not even synthetic and the filter was not original.

Anyways I decided to bring it to a Mercedes repair specialist. He put in the good Mobil synthetic oil and a Bosch filter. Light never came back.

Maybe it was the oil pressure with the bad oil.

Thanks,
Craig
