Hi there, I have 2003 A3 2.0 TDI that I've had since the sumner! It has an issue with the wipers...
Every now and then they would do 2or 3 slow sweeps followed by a manic 3 sweeps, going so fast they went off the edge of the screen! This happened now and then getting more regular over, say a month, until they did it and wouldn't stop- even if I turned the engine off they kept going!
I discovered I could stop them by popping the bonnet, as it jammed them- I was going to disconnect battery otherwise! I know it's not good jamming them but couldn't find fuse at the time!
Once started the next day they were fine, but yesterday, after a month or so, it started again and wouldn't stop!
Please help- I really can't affords the audi dealer and hoping it may be simple... Though in honesty sounds expensive!!
