    Having followed the recent correspondence on sourcing rear tyres, I am currently sourcing replacement Front Tyres and am looking for advice. I've already had a conversation as to whether I'd favour performance (Grip) over Fuel Economy (at which I laughed) - so Grip it is. I currently run on...

    Hi all, I could do with some help regarding the amp and speaker wires. My 91 850 is a project so I have bits missing. I have an amp which came out of my 95 840 but looking at the number of wires on the 840s loom harness this must be different as there are less wires on the 850s loom. Can anyone...

The car is manually locked with a key (no fob or anything fancy) and usually after about 15 minutes the doors simply unlock themselves. Is this electrical related?
