Hi all,
My diesel 940 is generally driving very well now I’ve taken care of most of the mechanical odds and sods on my to-do list.

However, I have a persistent noise that seems to be coming from something in the transmission region. I initially thought it was just happening in first and second, but it’s just more noticeable in those gears due to less road noise being present to mask it-it appears to be happening in all gears.

It only happens when the car is warm. It’s not quite a grinding or chattering noise, more a low pitched roar. It’s audible inside and outside the car, but only between 1000 and 1500rpm, after which it disappears entirely.

The clutch drags a little unless the pedal is fully depressed to the floor, and can sometimes judder a little on takeoff. Although it drags, the point of full engagement is quite high. Both of those factors make me question whether the noise is clutch related.

I have changed the gearbox oil which has had no effect on the noise whatsoever-it was identical before and after changing the oil, which makes me think it may be more clutch related than gearbox, as I’d expect at least a slight change in tone or volume with fresh oil if it was a box issue.

Gear changes, clutch drag aside, are absolutely fine and there are no issues with driving. I’m keen to diagnose it though as the noise is bugging me!

Any and all advice very much appreciated as always 🙂
