I got audi a4, it has got this problem for two weeks when i turn the key on wipers starts sweeping them self 10 times before they stop any where on the screen, and same thing happen again on turning the engine on, it happens when wipers are on off position. its really annoying, cause when i put it on on sweep it still does 10 sweeps before stopping in middle of screen
Hi - had the same problem with mine last year - turned out to be a sticky relay. You can probably hear it clicking with each wipe. These are well over £20 from the dealer, around £5-10 from a breaker, or if you like a challenge (like me) you can unclip the plastic cover off the relay and lightly dress the contacts with a nail board! Good luck.

Does the wiper sweep past the park correct park position before parking or does it just never go low enough. If it doesn't go low enough, simply loosen the wiper arm from the transmission and lower the wiper arm to the correct park position. If it sweeps past the park position you need to disconnect the motor from the transmission when the motor is in the park position. The move the transmission to the park position and reattach it to the motor.
remove both wiper arms, turn off the ignition. Set one arm on the spindle at the desired postion. Test the sweep of the wiper with the ignition on. Check for looseness of the spindles ( wheel boxes ), refit the second wiper arm in the correct position, checking for looseness , if all seems ok retest with the ignition on.
Check the crank arm on the wiper motor. There is a bracket under the crank arm that has a small upward part on it that the bottom of the crank arm is supposed to stop on when its shut off.
Put the wiper in the pulse position and turn the key on. let the wipers sweep one time then turn off the key.
Look under the crank arm to see where it stopped. It should be no farther than 5 mm from the bracket stop. The stop is often times bent or worn out. You will need to replace the crank arm and the bracket in most cases.
You need to adjust the wiper arm location. Loosen the 12 mm or 10 mm nut that holds the rear wiper arm. Wiggle the arm until it comes off. Then turn on the rear wiper for a second and turn it off, leaving the key on. This way the rear wiper motor will do it's sweep, and them park where it's suppose to. Then reattach the rear wiper arm and secure the nut and recheck.
We have a 2002 Audi A6 and I've just been doing a bit of self help to try and fix the inoperative wiper - the problem is one of the spindles on which ht ewiper arm sits is stuck - I managed to bang it out, grease it and put it back - but I just can't get the wipers positioned properly so that they sweep and park correctly - anyhow, back to your problem which presumably you have sorted by now? There are 3 clips fixing the cowl to the vehicle - one on the left, the centre and on the right hand side - the clips simply pull away but it is easier to do if you have a long nose pliers.
The most likely cause of your symptoms is the wiper motor parking relay has become faulty, however there is a slim possibility the connections within your wiper switch could be an issue, but the relay would be my first and cheepest line of enquiry. Contact your local VAG dealer and expect to pay somewhere in the region of £15. Good luck
