Just joined this site as I have been looking for an answer to this problem for over a month now. Car constantly relocks itself. Has been to the local mech x2 but he has not been able to find any answer. It is booked into the skoda dealership this coming monday and I have not been looking forward to the bill! Just popped out to have a look and sure enough ++ washer fluid in and around the base of the cd player. I can't see the break in the hose but will have a better look tomorrow. I suspect that the washer mix that that was in there when it all started on news year day - happy new year :-) - was an autumn mix of less than 50/50 and froze. I'll let you know if a clean up solves the problem!
Cheers Guys
Think I will cancel monday with the dealership.
