Sometimes shutting down the car would help as that seems to have allowed the BDC to reset itself and everything would work. However the latest code I'm getting as mentioned is "I've exceeded allowable short circuit resets." So I'm thinking either a fuse has blown at the BDC and or the unit will need to be recoded to allow power to the upper portion of the left side tail light.
I have not touched anything at the BDC nor did I run any extra wires from inner to outer as mentioned.
I am hoping that these lights are in fact OEM Bmw and not a knock-off made to look OEM. Going to dig and see if the BDC does have replaceable fuses for each light function as I'm stumped and driving around with a brake light not working.

Were you ever able to resolve this issue? I’m currently experiencing the short circuit to BDC impacting both taillights.

Who did the coding for you?

Get it recorded by Vik. You won’t believe how many PMs I get, all because these local guys in USA and Canada can’t code the LCI lights properly… every single time same story

Yes. I’ll reach out to Vik. I’m a bit nervous because this only happened after I loaded BM3. Tails worked flawlessly for about 6 months.

There’s also a hardware issue that was causing issues with the outer sections. It may be that. Had my driver side replaced under warranty.

If Vik isn’t able to address it with coding, I may have to reinstall the original tails to rule a hardware issue out. But could I be that lucky to have a hardware issue in both taillights?

At least the outer ones are pretty easy to remove and replace.

Vik was able to address the issue by resetting and recoding.

Hey sorry its been a minute. To answer your question-I did two things. First I ended up ordering two new OEM outer tail lights from ECS tuning on sale. Second( since I had the 5th wires available) I used the two extra wires and re-pinned the connections at the BDC instead of tapping outer to inners-as instructed very well in this thread.(I was wondering if the additional load of the inner tail light was causing the short circuit lock-outs) I felt bad having to constantly have Vic reset my BDC. I also downloaded INSTA and learned how to reset faults in the BDC.
The problem would drive me crazy so I figured on the chance I had defective lights and I could buy new ones at a decent price- and I did. So far the issue hasn't come back. Again thanks to fellow board members.

Yes. If I have to bother Vik again, this is exactly what I’ll do. Thanks!

Hey all,

So I got a set of tails from Abdul and they are genuine bmw.

I’ve now had 2 excellent coders check this and neither can sort this with coding.

Here’s the background.

2017 540i
Tested 5 sets of inner taillights same result. The issue is on the inners. I have the euro spec lci tails, with fog lights. Outer lights work perfect, jumped the signal to inners, that works perfect. Inner tails will light when off the brake and under brake with fog lights off.

The issue is when I have the rear fog lights on, the inner tail lights won’t bright up under braking. Mohsin and Vick have both attempted to sort this out with coding to no avail, I have 5 sets of inner tails from Abdul to attempt to sort the issue. (Amazing service by those guys for that btw). So that rules out hardware

It seems everything technically works, just not at the same time, since the brake lights work without the fog lights on. Anybody got ideas?

My last ditch effort is to jump the brake light from outer to inner, but I would really like to avoid that if possible.

I have the same issue and I have OEM Euro tails. The only difference between your install and mine is I ran the 5th wire directly from the BDC.

So just to make sure we are on the same page. When my rear fog is activated, only the drivers side inner tail fog light illuminates, not both. Supposedly this is by design and a requirement in a lot of countries as to not appear you are hitting the brakes.

When my fog is activated, the inner tails do not brake or light up on braking.

Vic was my coder. I can’t remember if I even asked him to look into the inners not lighting up when fog is on, but I did ask him to look into having both fogs light up and he couldn’t do it. I do know someone who has a 2017 540 that was able to code it himself successfully. I tried to copy his coding and found I did not have the same parameters.

At the end of the day, the fog light thing was more of an experiment and I honestly have zero practical application in real world Boston weather. Maybe Chicagoland is foggy.

I had the fog wire sitting there so I bought the switch and had Vic code it. I can’t even remember the last time I even thought of using it. Everything works fine with it off and honestly I am not quite sure that the inners not braking with fog on isn’t by design.

Long answer short, yes, mine do the same thing and it’s not the lights.

Thank you!

These are the types of things we are looking for instead of beating my head against a wall. Vick recommended me to jump the fog light over to get both on, works great, no errors.

And yes to confirm, my car is coded so right rear fog goes on, however when the rear fog is on, jumped or not, none of the inner tails light up under braking. I would imagine the car would be coded for the fog light laws and not the taillight though (BDC). But its def a route to look into. I have seen cars that have both fogs coded and all brake lights engaging under brake with fogs on. So it is possible.

[Silent540]

Ok so to confirm. I took the tails out to do a full reinstall. Here’s where we are so far.

I completel severed the brake wire going to the inner. Tapped the half going to the light to the outer brake light (2nd wire). Same results as before.

Which tells me the inner tail light under braking is not getting its signal from the brake line while fogs are on.

Which means, the fog light itself is essentially telling the tail light to cut all optional power to that tail light or voltage change to light up.

Next test is messing with the fog light coding to see if there is something in there that’s telling the inner tails to disable while it’s activated

Nice investigative work. You definitely ruled out some things. Sounds like coding would work if you have the parameters. As I mentioned, I did not. I did post the coding my friend did with ProTool on his 2017 540 where he got both fogs to light up and had the inners braking. It may be in this thread and may be helpful to you.

Hello guys,

I`m new to this forum, I bought 520i g30 (2019) in Europe and I want to upgrade the tail lights to LCI (EU spec). I`m not very technical person, so I would appreciate if you can answer some of my questions.

1) Regarding the repining process, do I just need to repin the wires in accordance to the instruction that was posted before? Do I need add any additional wires? I see that instructions are for the US or Canadian cars, however I have a European car. Can you please share repining instructions for the European car?

I`m asking this, because I found a youtube video where to guy is adding additional wires, so I`m a bit confused. Can you please share the repining instruction for the

2) Do I need to contact Vick after I have installed the new tail lights?


Thank you in advance,

Richard

Hi Richard,

I am pretty certain you need to follow the same instructions as US people putting Euro lights in US cars, but coding may be different, but you will still need coding. The only sure thing is that you will have a rear fog wire. The purpose of the jumper wire or extra wire from the BDC is to allow the inner tails to light up when braking or blinking, I can’t remember, but probably to allow the inner to blink for turn signal. Pre LCI tails on light up or blink on the outer when braking or for the turn signal, so I think you are going to need a jump wire detailed in this thread or you need to run an extra wire from the BCD for each side, this is what I did, but jump is easier.

Reach out to Vic via What’s app to confirm what I’m telling you. He will be happy to help and he will definitely confirm the answer. Then if he confirms, Follow these install instructions and then have Vic code. He is very famailir with the install of Euro lights on non US cars.

Good luck!

I wonder how many posts from this thread can be boiled down to “Contact Vic and call it a day.”

Joe, you are a patient man, brother.

Thanks Jake! I like helping people out. There may be something in this thread that has become a novel about the wiring for Euro lights in Euro cars, but nothing is popping into my head and I am not willing to re-read a thousand + posts. I did that when I jumped in on the LCI lights. I hope people take the time to try and skim or read through this thread before asking though.

Using my scan tool it tells me its detecting an intermittent or permanent short circuit and the BDC has to be reset by Vic. Very frustrating as I have to bother Vic for reprogramming each time. Doesn't happen right away and until it does the lights work fine.
Is it possible the lights are in fact knock-offs with bmw logo? The wiring has been verified correct to the inner lights and the rest are plug and play-as per the multiple instructions here and likeI stated they work for a while then all of a sudden poof. I have the NA spec LCI lights. Sorry if I missed a post where this was brought up.

I am having the same problem, have you found a resolution 😭
