Hi all, I've got an A4 estate, having problems with water coming in, I have cleaned out the thing under the battery but still getting serious amounts of water especially in the rear nearside foot well. the wipers have now seized up along with the central locking!! If possible id like to sort it out myself but don't know where to start as I'm not mechanically minded at all. I'm presuming the problems with wipers and locking is possibly due to the water damage? I cant afford to take the car to a garage and the bill would probably be more than the cars worth. Any advice would be gratefully received
