My B7 passat estate (2014 1.6 diesel) had a message on the dash to fix reversing lamp. I looked in back the car and the only thing I saw was this large LED on the left side (the inner light unit on the rear hatch).

I removed the unit and found it was built in, non-removable, glued shut assembly. I bought a replacement unit on ebay and installed it.
The LED still didn't work, however the actual incandescent reverse lamp on the outer unit (which I hadn't noticed) did now work.

The dash message now said replace right side reverse lamp. I took it out, checked bulb resistance, reinstalled it, and it worked again. I then replaced the entire original left unit to see if reverse lamps still worked. They did.
*Shrug* maybe the canbus got its knickers in a twist and reset somehow??

Anyway now my question is, what the hell is the big white LED lamp for? Is it a reverse lamp for high-spec cars only? Can it be activated in VCDS?

Update: I just realised, this may actually be the Rear Fog Light, in which case I feel really stupid. But its not working when I turn on fog light either.....


thanks

Very difficult to know until you post an Auto-Scan showing how your Passat is equipped and configured
