Burnt light connectors

Post by benhowarth6 » Thu Sep 12, 2019 6:38 pm

So last week I had intermittent light errors for the rear left. It started with just a few then all lights including the LED strips stoped working.

After removing the rear left cluster I noticed the middle ground pin had burnt completely. I repaired that by running a new ground wire bypassing the connector, then soldered directly to the ground inside the cluster. All has been fine since.

Today however the right side has done the same thing, which I’m planning on repairing tomorrow in the same way.

Is there a bigger issue that could be causing this perhaps that I should check for? I’ve not found much information apart from some F30’s which have done the same.

I’ve attached some images of the damaged connectors.

Car is a 63 120d m sport with xenons so it has the rear LED lights.

That sort of damage is usually cause by a loose connection. Being a poor contact it’s causes resistance and then heat.
