Well, to any interested, this is looking more and more like a gearbox problem so car will be going in for repair soon.
Dropping the gearbox, stripping it apart, replacing input shaft bearing and any other bearings that are going then putting back together.
Of course you'd be daft to do all of that and not replace the clutch so an S60R kit will go in while it's in bits.
Sigh.
Symptoms are:
- High pitched noise when cold starting on cold mornings that goes away after 30 seconds or so
- Noise also disappears when clutch pedal is pressed in
- Dry rattle/bearing noise can be heard at idle that goes with clutch pedal pressed in
- whining noise lower down the revs in 1st and 2nd, sounds a bit like reverse or an alternator bearing noise
Could be if I'm lucky clutch related, but it's sounding more like gearbox
These P1 Volvo's crap compared to the older models
