Frequently asked questions
Q. My BMW 3 Series Compact E46 rear wiper seems to have a life of its own. Sometimes it works and sometimes it doesn’t. Sometimes it keeps going longer than it should and then stops slightly short of the normal position! The rear wiper is used so very rarely I would be surprised if any part of the motor has worn out. Could it perhaps be some control unit somewhere? I can live without it but I worry that it could cause me a problem when the ITV is due.
A. It’s a very common problem water leaks into the mechanism because the washer pipe runs through the inside. The best remedy is to replace it with a new one; you can remove the old one and try and repair it or remove it and fit a rubber bung.
