I don't know if a bad BCM is your issue but probably not a bad guess. If you purchase a new or used BCM then you can certainly reprogram it with a Vag-com. That could also be a good investment to try and do some diagnosis on the issue as well.
Golf MK6 problem with lights and locking (BCM)
Hi,
My dad generously got me a 2013 Golf MK6 as a graduation gift. I really like the car, like the way it drives but the locks and lights do not work correctly and my dad oversaw that when buy the car unfortunately.
To be specific, the car-remote does not work at all, the door locks do not work until I turn on the car. Meaning every time I want to get in with passengers (which is alot) I have to unlock manually (with the key), then turn on the car, and only then will I be able to press the unlock button on the door to let them in. When the car is not turned on, the door locks button dont work and also, Im not able to open the hatch.
The lights also dont fully work, it seems they are always set to the night light (stronger lights), whether I switch the lights on or off, on the outside, nothing happens and the night lights are always turned on. The only thing I can do is pull the light dual and turn on the fog lights. Also when I turn the lights on and off the inside lights correctly turn on and off, its just not switching between the day and night headlights.
I give these 2 problem in the same post because I asked my uncle who is a somewhat of a mechanic and he confidently said this had to do with the Body Control Module and said something about replacing it and programming it. He mentioned he used to know someone who could program them but now lost contact with them, hence he told me he couldn't help me with this one.
At this point Im left with 2options: Option one, live with is and get rid of the car asap
or I could either try to fix it or have it fixed by a skilled mechanic.
What I want to know is, is he right? Could the locking and lights issue be related to the body control module? Also is replacing and programming it difficult? I am a software engineer so I have some programming knowledge, just not with cars..
If you read this far, thank you and sorry for the bad english(3rd language)

if you have sun roof check your BCM that's the only part controls most electronics, I had similar issues with my reverse light, get it out opened check for damage, the only way you can avoid reprograming if you can find one with the same serial number, or if you go to junkyard find one from a car with the same features, or ebay has tons of it for 150 dollars.

Thanks a lot for the help, I got a BCM and now am looking to get a vag-com to program itI don't know if a bad BCM is your issue but probably not a bad guess.

Thanks a lot for the reply, I found a bc-module but Im not sure about it will match my car, the one I got is 1K0 937 084 G compared to yours: 5K0 937 084 G. I would compare it to the current one I have nut my dad told me the bcm was probably swapped before so I dont trust the current one. My car is a tsi with sunroof (not leather) with 2.5 engine.if you have sun roof check your BCM that's the only part controls most electronics, I had similar issues with my reverse light, get it out opened check for damage, the only way you can avoid reprograming if you can find one with the same serial number, or if you go to junkyard find one from a car with the same features, or ebay has tons of it for 150 dollars.

Any idea where I could find a list of correct matching serial number for each mk6 model car?
