Rear wiper

[Byork]

Hi all firstly I'm new on here, I've recently got a A4 Avant 2007, ok the first issue is the rear wiper works on its own with out touching the wiper stalk ,would I just need to replace the wiper stalk ? Thanks in advance

Check mmi settings. Some cars have an option either to auto on when reverse or auto on when front wipers are on etc...

Hi I've checked and I can't see any auto wiper setting ,I'm just hoping it's a fault with the stalk
