Hello all. Got the dreaded triangle with LH driving lamp dead. All the other lamps function correctly. Changed the bulb (what a fiddle) but still dead - it appears the lamps are individually driven from the body control module, so for the moment have programmed them "off" from the menu. The question is - am I supposed to change the module for such a basic problem? Is there internal information available for the BCM (very basic Pop model) - ie, relays or solid state drivers and identification? Thanks in advance for any information.
 
I'd look at the rear plug first, by removing the bumper and or see if there's a feed on the respective wire? Or try removing the inner wheel arch liner, the small screws could be an issue
bulb holders for the DRL,s is a known week point wires come un-soldered, heat melts the holder,etc pull the wheel arch trim and if needed take the drl out of the bumper ( three bolts but awkward) and give it a good inspection!.
With it out of the car its easier to reconnect the main wiring plug, and test for feed voltage etc.
Replacement bulb holders are as rare as rocking horse poo!- if really bad might have to buy a replacement drl at around £60 for a pattern part!
good luck sorting it!.
