I've just picked up my new 540i and have been driving it around for a few days, following the break in procedures.
It didn't seem all that noisy when I collected it from the dealer but I have since noticed that the engine doesn't sound as smooth and quiet as I was expecting it to be at idle. It drives perfectly, but when it is idling, there is a noticeable rattling/tapping sound, most obviously on the drivers side of the car (I am in the UK, so it would be the passenger side for the rest of the world). It doesn't sound very nice and isn't what I was expecting from a 6 cylinder petrol engine.

The car is at the detailers being ceramic coated at the moment but I'm considering taking it back to the dealer to get it checked out.
Does this sound normal to anyone else? Thanks for any advice.
