I bought E60 530 LCI UK spec. So far I got mine checked at the workshop and no problems electronically. However I feel that the engine sound is a bit too loud. Apparently it's coming from valves or pistons inside (not very sure) but I'll get it diagnosed further. There's no harm yet but just that it sounds like a diesel car despite it being petrol
Squeaking sound on the doors after I apply tint. Apart from these, the car is so far so good.
