Yes, the Bose units do have a tendancy to skip, if you do a search you will find lots of info about it.
New pads, rotors and brake fluid should make a difference. No harm in giving the car a service, at least you know where you're at then.
Sounds like a plan.
I am pretty handy and so think I will do the work myself. I have found the guides pretty helpfull on here and can't see a problem doing the diff, gearbox and coolant flush. Especially as a friend has a pit I can use.
Done the oil, filter, disks and pads loads of times on other cars.
It's funny because the more I use the car the better it drives. Done about 500miles in it in the last 10 days and its really freeing off.
The girlfriend has to go to London so might give it to her to get another 400m in.
