Hi everyone,
I'm having some more issues with the lights on my mk5 :scared:
Im now getting a brake light failure message and a bulb light on the dash. it says both lights are defective but i have replaced both the bulbs and they both work when the pedal is pressed. I saw the other day that when i unlock the car and the lights turn on automatically, the outside brake light turns on for a few seconds then goes off (as shown in the video)

(apologies for the weird aspect ratio)
Anyone got any ideas? Ive found that in cold weather the car gets a bit funny, saying either the parking light is out, or the indicator light is out but then when i indicate for the first time since start up, the light flashes quicker than normal a few times then goes back to what it should be doing. Is my CECM on the way out?
Any help would be greatly appreciated!!

The looms that pass through the tailgate and into the roof are apparently prone to wear and chaffing. Perhaps pop the grommets out and make sure no wires are shorting together or snapped?
If not that, a dodgy central electronics ECU or something?

i am sure i had read somewhere that when the bulb test senses a bulb failure it turns off the signal to the bulb, hence why it turns off. i would guess it it not sensing correctly and so it thinks the bulb is out, even though we can see it is good,

Id suggest taking it to an electrician, my old one its tail light used to flicker like mad and then a few leds popped

I still haven't had a chance to look at this, but my battery keeps dying now... Do you think it could be related to the wires potentially shorting together? It was a brand new battery around 3 months ago.
I seem to get a new problem every month :(
