Hi all. Our x35 Diesel just started this annoying squeak, I've disassembled a part of the dash and when I put my scope the squeak is very strong in the metal sub-assembly inside the dash.
But I have no idea where to start as I think it's coming from just under the dash but is also audible from outside the car.
It's pretty much when the car is moving. I've spent about 3 or 4 hours poking around, took apart most of the dash but short of removing the dashpad and wondering how others have dealt with it.
Not really looking forward to another insane dealer bill. Last one was $1800.
Here's a short recording of the sound.
