Interior Lighting Problem - Mk 7

[R-head]

Hi all,

I have a problem with all my main interior lights, cabin (roof 3 and the 2 footwell ambient) and boot; they basically won't come on when doors are opened or the car is unlocked.

Now all my interior lights have been changed to LED for the past 8 months or so. Now I have carried out the GEM self test as detailed in the Haynes manual (Chapter 12 Section 3 para 12) and everything passes but the interior light test, so this may indicate the GEM is at fault that or the wiring which is common may be the culprit?

Next step is to reset the whole thing by disconnecting the battery, I believe a few hours is right. If this does not sort it I guess I'll have to start delving further and perhaps a few continuity check of the wiring.

Whilst I know what direction to take I'm looking at a few other things to consider. I have heard that LED lights in some systems can cause a failure after a little time, could this perhaps be a factor in this car, I've not heard of anyone else having problems though?

What are your opinions?

Jim
