Just found out the problem i have had with my alarm flashing and the car thinking the boot was open. Apparently the mk4 rear washer motor comes disconected from the pipe that supplies it thus flooding the boot catch making it think its open. if any of u have this problem then jst remove the boot panel (which takes alot of force to get off, so much i have cracked it slightly) by removing the screws in the grips inside the boot. and leave to dry. This is a very common fault! hope that helps for all u mk 4 owners Pat
