I posted about a noise a few days back and it's gotten worse (car is with BMW now).
It's a constant woosh now coming from the right hand side of the engine bay.
BMW said they can't find anything wrong (no cel codes) and it's fine.
The car has lost a lot of power and it's embarrassing to drive around with what sounds like a Dyson underneath the bonnet.
Any idea what it is ? Video below.
