BMW petrol sounds like diesel at idle - AM
Hi, have new shape 320ise petrol N46 engine, 9000 miles on clock. Ever since I got it a couple of months ago, thought that it sounded a bit like a diesel at idle. Driving it the engine is near silent and very smooth from inside. But when idling it does sound slightly diesel like. At recent first oil service mentioned it to dealer who said nothing wrong with it.

Anyone else noticed this?

Thanks

MY 1999 318i also sounded like a diesel at idle, but in all other respects was fine engine wise.

Mate,

I have a number of mates who have BMW, and yes, they all sound like tractors at idle (esp when cold)..I think it is the hyd tappets.
