Bmw angel eyes

[bpd1984]

Hi all sorry for the long posy I've got an x3 with adaptive headlights the drivers side Angel eyes don't work but passenger side do I swapped the tms unit over from one side to the other yesterday then neither worked so put back to how it was and passenger side still working does anyone know if the tms module has to be coded for each side and this could be the reason it didn't work when swapped over? 
Many thanks

Morning Ben

You need someone with ISTA/INPA Diagnostics as that will also in WIS (Workshop Information System) and TIS (Technical Information System) 

I will look later but just back from the Horses and now off to Dog Training when home I will fire up the Garage Laptop and see what I can find

Ok great thank you I've had it code read and it said fault code 805e3a daytime lights voltage lower than target value if that helps anymore?

Hi Ben

Back home again the code you have is pointing to the LED bulbs for the angle eyes are faulty. There are 2 in each headlight. Just replace them with new ones and make sure the semi transparent seals are there to avoid water ingress. Then initialize the headlights via ISTA and all should be good.

Hi Dave many thanks am I wrong in thinking the bulbs are built in and have to break the headlight apart?

Sorry to be a pain but what would cause both sides to no work whe  I swap the tms units from one side to the other if was the bulbs?
