Could you please tell me how to re-time the wiper linkage and what position the linkage should be in before connecting to the motor? I had to remove the old linkage as the driver side was seized and on trying to free it off with gentle persuassion the threads on the spindle sheared off. I am currently waiting for a new linkage, from Audi.

normally if the wiper arms park in the wrong place , it is the fitting of the wiper arms on the pivot that is wrong
try pulling the wipers back off the windscreen , run them through a cycle and then switch off normally
that will be the park position in the motor gear box
then remove each arm from the pivot and re- position it about 1" from the bottom of the screen
that will be the parked position for the wiper blades
having done that then again pull the arms back of the screen and cycle as if wiping the screen
switch of and see where the arms now park on the screen
if it is close to where you set them then that is the park position
next run the wipers a cycle and see if at full movement one arm puts the blade over the edge of the screen or hits the edge
switch off and re-position that arm closer to the bottom of the windscreen
it is time consuming but the only way to park wipers properly as there is no master spline to set in the correct position
If they park any where after this exercise ,replace the wiper unit as there is a problem in the contacts in the motor box.
the wiper arm may have come loose from the motor linkage , where the arm joins the linkage outside of bonnet/hood there is a flip up cap , under there is a nut that holds the wiper arm in position , this may be loose so remove completely then remove the arm as the splines may not be in the correct position, replace the arm so that when it is laid back down on windscreen it is level with the bottom and tighten the nut , you must tighten the nut with the wiper arm raised so as to get a good fit , this may require a couple of attempts to get in the exact position when wiper arm is laid back down, hope that makes sense
Remove the wiper arms completely. Turn on the wiper motor and then turn it off again, allowing it to park automatically.
Now put the wiper arms back so that the blades just touch the bottom edge of the windscreen, or wherever the correct position is. Tighten the nuts
Sorry but your description doesn't really make sense - the wipers work, you say, but when switched on they remain in the correct parked position...
Presumably when switched off they park vertically.
It is worth noting the single sweep timer and the screenwash (5 wiper sweeps) influences the self parking. The circuit is quite complicated and it is best not to be involved unless necessary and then a circuit diagram would be invaluable.
It is also important the wiper linkage crank is correctly "timed" to the wiper motor for correct parking.
The wiper motor and integrated gearbox is fairly simple to examine and test but the gearbox also contains the self parking switch which can be examined for wear and cleanliness though testing isn't very practical.
I suggest you begin by removing the wiper motor and examining the condition of the self parking switch inside the gearbox. If it is worn or corroded replace the motor. When refitting connect the wiring and switch on the ignition and then briefly switch on the wiper motor and switch off. The motor should continue for a second or two and then stop.
Switch off the ignition.
Position the wiper blades in the proper parked position and then refit the wiper linkage crank to the motor...
Hey there. I had a similar problem on my 2001 galaxy diesel. On research it's a very common problem. If you are mechanically minded it can be an easy fix with a bit of time. You need to remove the whole wiper linkage and motor and free out the bushes that hold the wipers in position applying pbc grease before refitting. Continued use will only result in your motor burning out which is 350+euro from ford and if the linkage seizes completely then another 400+euro so catch it before it's too late.
The wiper motor is situated under the plastic air intake cover at the bottom of the wind screen.Remove the wiper arms and the clips holding the cover on , replace the wiper motor and operate before putting the wiper arms back to return the motor to it's park position.
