Firstly, i am sorry if such a thread already exists, i've searched everywhere and found no solution.


What happened

Firstly, my reverse light stopped working. (the white lights that light up when putting in R) After that, the three "LED" -ish lines on the trunk lid died on the right side, shortly after, the left went with it. It left me a little bit of pissed off
since i've changed the front headlight bulb just a week before and i thought that the bulb change would be annoying as chaninging headlight bulbs.

What i've done
I removed the trunklid inner panel and changed the bulbs, only one (on the right side reverse light bulb) looked burnt, i mean like when you change bulbs at home and you see black-ish smoke inside of the glass. I changed the reverse light bulbs and the "LED"ish 3 lines position light bulbs. All bulbs we're correct amps and watts.

Results
Well, i can't figure out whats wrong but they don't seem to work. the left hand side of the LED lights works again, and the right hand sight did work. But 3 weeks ago they went out and stopped working since, Sometimes they light up when i open and close the trunk. Same with reverse lights, the right one used to light up when i put it in R, but only for like 4 seconds.


What it looks like..(The car is in reverse with the handbrake on)
I've checked the cables on the right side of the trunk and replaced the fuses. Still no cigar..

I went to a dealer that i know and he said something about not beeing "grounded" or something like that, im not an electrican. unfortunately..

So anybody have any ideas and thoughts?

Replace all the bulbs and your issue will be fixed. One of your bulbs isn't working right. The car's ECU picks up that one bulb isn't working and will switch to another bulb for safety reasons. For example, if your parking light (Your so-called LED strip ) is out, the car's computer will make one of the brake lights turn on dimly to compensate.

when this happens, does the bulb out warning go out, or will it continue to remind you that a bulb is out?

i get a bulb out warning occasionally when i start my car, then after awhile the warning just goes away.

i havent changed any of the bulbs in my car, as far as i know, they are all stock.

As far as I know the bulb out warnings will only show at startup, if the ECU detects a bulb voltage issue. One of your bulbs may have blown, so I would look at your's to make sure.

When you get the bulb error press and hold the stalk until you see a CC-ID#. Look that up and it'll give you more specifics. If you change the bulbs and it's still giving you an error then it's faulty wiring (essentially what the dealer told you)

Thanks you guys. By pressing the stalk you mean the BC button? I don't have iDrive so thats pretty much the only way to control the on board computer. I'll try to change all the bulbs on monday when i get back .
