Hi being a bit paranoid about my car since I haven't had it long and already had a couple of problems.
When the engine is warm and on idle from outside you can here a faint rattle / electric injector opening tick noise, seems to be coming from underneath the top cover area of the engine. The car drives ok ,oil ok , not noticeable from inside,thought it was the fan at first but does it without that turning. It is going in for some exhaust repair to bmw so might be something to do with that?
1st bmw so not sure how quiet these engines are , thought someone might have some ideas.
