Vibration noise
Hello to all. I'm the new kid on the block ok old man on the block. I've purchased a Z4 2003 3.0 130k auto So far I've replaced the Disa valve, cleaned the idle control valve, and waiting for a crankcase breather hose. At and only at 1750 rpm there is a vibration noise coming from behind engine only under power will not do it in neutral. Sounds like a really mad bumblebee. Any help would be appreciated.

Welcome!
May be difficult but try to record the sound
If it’s under load in that area it may be clutch/flywheel related but hard to say without hearing it

I’ve had head shields work loose and corrode before
That’s worth a look especially at the one that sits drivers side (uk rhd car) side

You can’t miss it
It’s a bright silver aluminium shield that sits on the side of the engine where the exhausts are- check that’s not loose?

Think it was meant to read heat shield
All good things come to those who wait. I'm really impatient which explains a lot.

If anyone has had this problem this is what I found. I replaced the passenger moter mount and no more noise.
