My coder tells me that I need to have the jumper for them to work as the US spec light. Here is my wiring without the jumper.
I am really confused and can’t find any official source to clarify whether a jumper is required or not for US spec cars with US spec LCI lights.
Hmmmm....if you read the first 10 pages or so of this thread, the installers were predominantly installing US LCI lights on US cars before we all discovered that the Euro's didn't have welcome light issues, but required extra wires from the BDC, which serves the same purpose as the jumper. None of the folks installing US lights on US cars needed a jumper wire.

Who is your coder? If it is not Vic, then my hunch is they don't know what they are doing. I have seen this many times. They are unable to resolve the coding needed and they start guessing at wiring issues.

Reach out to Vic. You will have the welcome light error and will have to shut it down in iDrive like others.

That’s what my suspicion is. I read through this threat multiple times and came to the same conclusion. My coder is Brandon Lewis from Nevada. I got his name from one if the G30 forums on Facebook. He is sticking to his view that I need a jumper where I cannot find any evidence of this claim. Inly evidence he can provide is bulletin from EU BMW which I know doesn’t apply to US. I am at a loss how to prove it to him that he needs to look at his coding. I have also sent a message to Vic.
Strange thing is my lights are behaving exactly like an EU car.

My money is on Vic to get you going in 15 minutes. Story, Vic coded my lights and then coded my rear fog light/switch. I noticed a minor anomaly (can't remember what it was) several months later when I was backing up in a parking lot at night and could see my brake lights reflecting off store window glass.

I reached out to Vic and he was out of pocket for the next week or so. In my impatience and off the charts OCD, I just wanted it fixed and made the mistake of having a different coder who said they knew what they were doing go in. He totally fucked up my coding and I was literally in the garage connected with him for 3 hours until 2AM when he declared it had to be a wiring issue.

I paid him and What's Apped Vic and came clean. Ironically he was available. Back in the garage at 2AM, he went in and fixed his mess and corrected the anomaly I was having in 15 minutes.

Lessoned learned. I reached out to the coder and told him Vic fixed it 15 minutes and he pleaded with me to let him go in and see the coding. No dice, that is Vic's intellectual property. He refunded my money.

Facebook is not the best place to find a coder. They are vultures on those groups looking for business.

It's 100% a coding issue if you wired it according to Euro's DIY.

Great advise. I have own Bimmers for long time and been part of lots of groups. You are absolutely right. I will get it sorted out and report back. This exercise also took a long time. 😊 The reason I went with this coder was that US to US wasn’t a big coding job and there was a recommendation on G30 USA Group. .

Definitely report back. Yeah, I was a member in that Group for a while but left about a year ago. As the cars get cheaper, the audience/owners are hard to identify with. Lots of newbies looking to rice out the car, go catless and fight with you over the B58 being better than the N63 and the N63 crowd claiming that "basically have an M5".....the M550 ain't no M5.

Good luck.
