Supeerrr. Thank you. On my 2002e46 318i was a grey wire broken in the same bunch of wires. That was the reason I had boot lid open light on the dashboard. Now it is fixed thanks to you. THANK YOU.

what wire color is the tail light bulb? BMW e90

You are straight on point. i cant believe i found 4 wires broken, Thanks you so much for the video

Great video there mate... Just wonder on how did you manage to open up the boot lid when it got stuck close? Cuz my E90 (UK version 2011) got stuck and won't open up at all... No key holes and no wire latch or valet switch or whatsoever to open up the boot... Thanks for ur help

I literally had the exact same problem today and by watching your video, I managed to fix it all! Thank you soo much! I also had the same exact wires chopped in half.

Hey how's it going I have the same issue . Just wondering how long you had the error message before you fixed it ? Aproximate amount of ignition cycles ?? Thank you

Thank you thank you thank you!! This was my issue

Excellent video, I now know the fix, but I cant access the boot. Key remote not working, no boot switch in glove and no manual lock to open with key. My boot is completely inaccessible E90 2011 318d

Thank You. I managed to fix my boot thanx to this video.

Having exactly same problem… pls help

Dude.... I had those exact 2 wires broken. Just like you I just pulled 2 thick broken brown wires out. And looking at all the comments, this is a very common issue that BMW should issue a recall for

thank you - 6 years later.

Hello, my bundle has a single wire cut on my BMW E90 and the trunk no longer opens. The problem is, I can't see how to open the safe from inside the safe. I do not see a manual control? Someone could help me, because without opening the safe I cannot fix my harness ... Thank you all for your help

This was the exact issue i had, thanks a lot!

Good job

Part #2320055 is a kit to replace the entire trunk wiring section with the rubber boot. I opted for this because I didn't want to have to potentially fix it "again" if other wires started having issues. The wires are pre-crimped and have heatshrink connectors ready to go.

This video was a life saver! Had exactly the same problem and found a broken wire in the boot harness. All sorted now. Many thanks ..

My problem is just with the left license plate light and I’ve switched out the hosing with a new one, looked inside the cover for frayed wires and looked under the rubber connection for split wires like yours and can’t find the problem, I’m getting 0volts, any ideas?

Great guide! If it didn't happen to me I'd think it was highly unlikely that just opening and closing the trunk would break a wire but sure enough, this was it. I was freaking out thinking it was something major. I actually just finished the repair, also by fishing a small gauge wire then pulling the new section back through. Some people are lazy and cut the sleeve but this isn't very hard at all and keeps everything looking original, not to mention perfectly waterproof. Again, great video.

Many thanks mate. Going to give it a try as same problems. Thanks for sharing.

That annoying rubber

Hey thanks for the tip. I did find this same issue on my E91 (wagon). Two wires had completely split, about 4 others were ready to go. Once I patched the broken wires all the issues I was having went away.

Good to see this is a common fault and not a car killer, I think the angle of the whole thing is wrong and just aids it

Thanks Mundip - I had exactly the same problem, and had no idea where to start looking for the fault, but came across your video and problem now resolved !

Thank you Mundip, going through this exact issue, found the two wires, will head to hardware to grab the wires. Appreciate it a lot!!

I have a 2008 bmw e90 saloon and my boot has just stopped opening, and the number plate lights along with rear lhs fog, reverse and lights have stopped working, I assume this may be the reason?

Thanks man. I have an E46 but this video was helpful. Through this video I managed to trace the problem.

Great video, found I had five broken wires! Boot lock, fog lamp, number plate light, rear light one side, plus not sure what the other one did? Only thing though after about an hour trying to get a wire through I cut the cover and then finished taped it with insulation tape, looks ok plus the car is 12 years old so not too worried, but your video was a great help, thank you very much, probably saved me £150 plus.

Great video, hopefully some of my wires in there are broken and causing the problems I have. Looking forward to checking it out

I racked my brains thinking about how I could fix two wires without ruining or being able to replace the rubber boot... and this was the perfect solution. Thanks so much for posting! Thanks for a concise, informative video too.

My bmw opens the trunk when i switch on the headlights and also when i press the brake pedal with lights on it triggers the trunk switch on and off, can the problem be those wires.thank you

This vid is fruitful, thanks man you've saved me a lot of money. In my case it was 1brown wire .

Brilliant! Great stuff man, thanks :D I started getting warning lights for bulbs and fog lights, then the trunk mechanism wouldn't open, this resolved it!

I just found the same problem on my E90 320D. Without this video I wouldn't have looked for this issue at all. THANK YOU!

Thanks! Had the same issue and fixed it this morning. Very helpful video.

Thank you! I had checked this harness but NOT thoroughly enough UNTIL watching YOUR video; upon which I discovered the very same two brown wires severed! They pulled up very easily.

What is the voltage of the wiring

2:45 When I took the rubber connector off the car, there is another rubber cover that keeps going inside my car... so I cannot see the wires on the car body side... how do I remove this?

Thanks that’s great help!!

Great vid. How's the general reliability of your 320i engine and how long have you had it for? What else has gone wrong on your car?

I had light problem and when wiggled wires they worked and I thought would be expensive after watching your video I went out and fixed it cost me £9 thank you for showing me how easy it was

Hay I had number plate lights out plus no auto boot or left hand reverse light + light on boot lid + light in boot out ,and guess what ! It was that bloody brown wire,much thanks

Thanks for sharing, had the same issue and glad I came across your video,it was easy fix,compare to the $400 at the dealer 🥂

Haven the same problem,tail lights on my boot left side not working

I have this exact issue, I have a fault for bothering right tail light and reverse light.. both are located in the trunk lid. I wiggled the rubber covered joining harness and saw the lights flicker. Funny thing before this happened, for the longest time I had a fault code for both tail lights out and they weren’t out.

the classics

Many thanks Mundip, saved me long trips to service centre, not to mention the costs. I had done this repair myself on my previous e36, but I am 12 years older now. Fixed in 30 mins at zero cost, using only soldered joints. Without your video I would have cut the gaiter. I used a coat hanger to thread the replacement cable, soldering to the end and pulling it back through.

Thanks for this vid. Just managed to fix mine. Had one ground cable broken and about 3o r 4 with the insulation damaged.

Thank you! Have same issue will check tomorrow and im very sure its sameproblem on my 2005 e90

Thank you very much for taking the time to post this video as i had the same issue on my 325i E90.It took me around an hour to fix and i used a 13amp flex,connecters and electrical tape...cost me about £5,significantly less than going to an auto electrician. 😁👌👍
