Exterior Lighting Problems

Post by aofb »

Hi all.

My B6 is a bit wonky lighting wise.
I've lost all OSF lights, OSR indicator and one of two OSR tail lights, OS brake light plus one of two NS tail lights.

All bulbs / LEDs are OK. There's 0.4v at the lighting loom connection (I'm assuming this is the voltage for the bulb failure detection current) and earth integrity seems to be OK throughout.
Code scan has a Central Electronics Unit out of sync fault, cleared it to no effect.

I'm thinking the J519 / Central Electronics Unit has partly died.

Planning a full loom validation over the weekend.

Anyone got any other suggestions?

Cheers
