My wife's 2014 Evoque's left rear brake light stopped working a week ago. I did notice however that the brake light worked when the ignition was on, but went off as soon as the engine was started.
I examined the unit, all looked ok, but realised of course that the brake light is LED, thus not replaceable, so £200+ for a new unit. I was dubious whether even buying a new unit would work, since the light seems to function ok with no engine running. So I invested in an iCarsoft LR V2.0 scanner, and it did identify a brake light fault. I reset it, but still no joy.
Coincidentally I had arranged for a mobile tech to call on Tuesday and update the gearbox software on my 2013 FL2 Auto, so I asked him to help with the Evoque. His diagnostic tool identified a short circuit fault on the brake light feed, and he also tried a reset that failed. He then updated the software on the Evoque and hey-presto it began to work again ok. We put it down to water getting into the housing at some time previous, and the auto-protection gubbings in the ECU (can't remember the acronym) disabled the circuit, so hopefully it might be ok now for a while. However the next day it failed again.
He had never come across this issue before, and I can't find anything similar via Google. The thought of having to trace a repair the wiring is either mindbogglingly difficult (DIY) or ridiculously expensive (Main Dealer).
Further Googling of different brakes (esp X3's it seems) does suggest the LED driver may be a possible culprit, so buying a full new unit may be the best fix. Has anyone had such problems with brake lights on an Evoque?
