Engine noise at idle

Hey all

Not sure if I have a slight engine knock.....only noticed while giving the car a start and idle for 10 mins....maybe normal. No error codes and drives spot on.

I am no expert, but having owned M54 engines for 15 years, I would be concerned by that noise.
Have you checked oil level?

Yeah...oil level is fine. Car has been sitting a fair bit last 6 months. Service in a few weeks so will get it checked out.. as I say, no codes amd pulls as well as ever.
