HI Have an A4 Avant 20.TDI. The rear windscreen wiper works, but when operated the final resting position is vertical not horizontal. Any help would be appreciated.

Hi I have a A4 Avant 2.0 TDI which has done 102 K. It's my first Audi and I've just noticed that at certain times I can smell exhaust fumes and the engine seems to use more fuel. I've had the exhaust checked and no issues were found. At the same time the engine feels like it miss fires, When driving I sometimes feel the engine losses power for a split second then bounces back. Any help would be appreciated.
