Today I got my R back, after dropping it off at Pulman Durham on Monday evening and picking up a Polo 1.2TSI. The car isn't fixed yet, but they have persuaded VW to sanction a replacement ACC sensor. They also spotted my rubber trunking between the back of the car and the boot needed replacing without me mentioning it (I snapped a clip fitting a dashcam that has since been removed). The parts are on backorder, so the car will be back to them for fitment in 7 to 10 days.
My R got the special treatment while with them. They've given it the "new car collection" going over - hand washed, waxed, blacked the tyre walls, dedusted and polished the dash and hoovered the footwells. I think my salesman must've had a word with them after seeing my car back with them yet again.
Then I drove it home the scenic route....like I stole it. It's amazing how heavy the steering felt after driving the Polo for 3 days, 5 mins into the drive and the steering feels normal again.
