We have a 1997 TDi sport.
It has a problem with the remote central locking. basically it doesnt work all of the time.
Some time it will work on the first click of the remote, other times you have to click it many times before it responds. We have given up using it and just use the key instead.

When it does respond its fine, all doors unlock or lock. I've put a new battery in the key, but thats had no affect at all.

Footwell is dry in case you were going to suggest water ingress.

Any ideas??

Thanks
Alan
