My A4 Avant 2.5 Tdi has just come up with a new trick - she now runs the rear wiper when the front washers are requested (ie pull stalk towards steering wheel)
The washers don't start at all.
The rear wiper still works correctly when the stalk is in the normal position for this (ie pushed furthest away from steering wheel)
This had never occurred before and started immediately from start of trip after standing for a few days.
Anybody had this before? I've searched through hundreds of threads, but can't seem to find any similar.
I would welcome any opinions - is it likely to be sticking relay (if so which one and where would be an added bonus) or is this function related to software and might possibly reset with a battery disconnect?
Any help from the astonishing expertise on this forum would be very much appreciated, and thanks for previous topics. Chris
