Had an issue with the rear wiper on my 2007 A3, wiper blade went past the window and rested on the paint work. On inspection the inner gear section had worn allowing excessive movement. So got myself a replacement of e-bay and cured the excessive movement :yes: However the bloody thing leaks! Sent a message to the seller, still awaiting a response. Is the gasket available for these?? Wondering if I could salvage the unit???? I have seen the repair kits but just need the gasket - or has anyone had any success with liquid gasket??
