Evening all... I've had a bad weekend. Thursday night, managed to leave all four windows open during a rain storm, The rear passenger footwell is now sodden wet (I have no idea why the other footwells are dry). Of course, I'm assuming it's because the windows were open... I suppose I just need to let it dry out over time? Saturday morning, went to buy a new tyre at a tyre centre in Horden, Peterlee (NE England). Upon arrival, and forgetting that my new A6 is 20mm lower than my old A4, I pranged the front valence on a kerb while parking up. Net result, the lower bumper is scratched to buggery, and the undertray has been dislodged. So, once I'd gotten over that, the new NSR tyre was fitted (and the unused spare was fitted to the OSR) meaning I had two new tyres on the back of the car. Smashing. Saturday night, on the way back from the cinema, I became aware of a worrying vibration over 60mph. I'm thinking perhaps either the new tyre or original spare has some kind of defect. Either way, it's a bit worrying. Any ideas? Could my wheel alignment be out? Problem is, I've had to drive back up to fife so it isn't easy to go back to the tyre place to check it out. Not a good weekend! A.
