My x5 is a 2012 model so assumed it had new style gasket may have to bite the bullet check both lights and restock bmw roundel to make sure no further water ingress

Hi all

Having problem with a inner taillight led not working.
Don’t want to replace till I find the cause. Is it due to the water leak/ seal failure. As on a number of occasions had water drip from the tail gate lock.
I was also wondering if the water was penetrating from the bmw roundel logo on ...
