Hi there,
About a month ago my car has developed some rattle.Noise seem to be coming from the front(front right,hard to say really) of the engine.Noise is present regardless of engine temperature but you can't hear it until revs drop to 600 rpms when cold.Noise is more or less intermittent(can go silent for 2-7 seconds but will come back again).When on halt with D/R or with AC on it is nearly constant.Disa valve #1 one replaced around month ago but rattle is still there.
I wanted to drop the belt to eliminate all the pulleys etc but there is little to no room to work and I'm afraid that I won't be able to put it back again.

Car is 2006 E60 525i N52B25 with 75k on the clock.

Here is a vid-engine on tepm,on P with ac off:

It sounds like one of the the pulley about to give. When my AC compressor pulley bearing give in, that was what it sounded like. Check all the pulleys, belt tensioner etc, for play, you might able to see the bad one wobbling. hope that will help. GL

Exhaust bracket , right under drivers side if right hand drive car its bolted to the gearbox ,thats what mine was but mine is 520d ...exact noise , i also tought it was coming from around the engine. Im not too sure with the petrol one though if they give that trouble worth a look
