Morning Lee

Welcome to the Forum

Does the noise rise and fall with engine rev's ? It could be a failed ballast suppressor on the Alternator 

Or is the noise there with the engine off ? It could be a fault with the Amp or speakers

      To runflat or not to runflat.

      With the E53 4.6is at the first change yes (Admiral at that time) and like LV as long as they were the correct size and rating it was of little interest. I have to say I haven't bothered since Dave

      2016 x6 3.0d. 70k miles

      Morning Paul Sorry to hear that, the Mechanic was I fear generating work at your expence. First sign of chain wear is a definite rattle on cold start, if you listen with a probe you will hear a wooshing sound as the chain guides are a type of plastic. If someone tells you chain wear drain the oil and filter it through a paper coffee filter any metal bits will show up in the filter My brother inlaw has run 5 series Touring since the early 2000's he is now on his 6th all have been 3.0d (basically the same engine) or its diretives all have been ECU tuned, the current one 540d xDrive runs almost 400hp. His business is Europe based so his cars get driven hard and all have exceeded 200k before trading in for the next model. All have had full BMW histories with interim oil and filter changes at 5 to 6k intervals. He has had some odd bits fail as we all do but never had a chain problem. Dave
