Few questions....
The wing mirrors don’t fold in and you can’t change the angle of the glass from the control on the drivers door.
doesnt sound right, did you select the mirror you wanted to adjust?
Never had a chance to check the blis out, it did light up though/ is there any known problems with that? -
if you have Blis the mirrors should fold (button on the lower switch panel.)
The drivers seat plastic that’s around the controls to move it is all burst, are they easy and cheap enough to buy from Volvo? -
approx £20'ish from Volvo and 10 mins to change
Had a look at the rear shocks, engine pads, CD player and reverse sensors and they all work and from what I’ve read they are common on going faulty.
Failing Nivomats is not that common I believe, engine mounts is wear and tear, and the reverse sensors have various service advisories, so check they have been done. Also knowing what year, and model + engine would be helpful when asking questions.
