Got my R back today, the long-winded way - having 2 cars and only 1 legal driver (so far, the wife's driving test is later this month) in the household is a bit of a bugger.
First day in the new job at Prudhoe (11 miles west of Newcastle), drove the A1 there. Got a slightly early finish, drove the A1 to Newcastle centre for some free evening multistory parking then jumped on the Metro to Sunderland, getting off at the stop a 10 min walk away from Pulman Durham. Pick the R up, drive it 10 miles due North through the Tyne Tunnel (ACC "no view" warning is up again - must be a system limitation), get home, walk to the Metro near home and get it back into the Toon to pick up the A1 and drive it home. Not the easiest way to do it, but the quickest way to get to Sunderland from Prudhoe before the dealership closed.
The R's drive home.....The new turbo sounds very nice, much raspier than before.
No, they haven't messed with the Soundaktor and turned it back up, that raspy noise heard is the raw noise with the windows open. My wastegate rattle sounds a little louder than before though.
I asked them to look at that. Characteristic noise or not, metal on metal means only 1 thing - wear.
