Hi,
Recently bought a 2016 GTI with a headlight upgrade to mk7.5 LED headlights which didn't work to start with.
However after some help, I retrofitted a 4B module and changed up the BCM. Re-Coded the adaptations etc and got everything working...except the HORN!
When I plug the old BCM back in, the horn works! There are very few coding changes relating to the Signal Horn.
I've replaced the Steering Wheel J527 module to one from a 2017 golf which had the same upgraded BCM I'm now using..and still no joy.
Am I right in now thinking the new BCM must have a fault??
Old BCM 5Q0937084AS
New BCM 5Q0939084CF
Any and all help welcomed.
Thanks
Sam
