Hi guys

Wonder if anyone can point me in the right direction??

The wife's 3 door 2.0Tdi A3 has recently started having problems with the rear wiper and the alarm going off. The computer inside says the tailgate is open when it is shut so the alarm keeps going off. It seems intermittent though, sometimes the boot does think it's shut and the wiper sometimes works but not the washer.
This all seems to have started when the rear wiper and washer stopped working! I did have a search back at some older posts that did touch on similar problems but none exactly to what I'm experiencing.

Any ideas?

Cheers

Ayron
