Current facing an issue with my Q5 after replacing a new Headlamp and new DLR Control Module.

Issue : Led lights only appear for less than 1 second after switching it on.

Base on my research, early Q5's owner have been facing this kind of issue as mojority respond to the defective DRL Control Module.

I can't seen to find the part numbers of all those defected modules. Any solution ? Please do reply ASAP

If so anyone knows the defective DLR part numbers, please do list it down . thankiewwww

Normally I'd ask for a VCDS log and then be able to ascertain year/model of Q5, but there are a number of threads which speak to such issues, take a look and if at all possible, this should be something covered under warranty. Check out TSB 2020780/3

Your issue MAY be related, but since yours actually turns on for a second, without proper diagnostic equipment this is extremely difficult to troubleshoot.
