Hello all. Ive just bought my first camper which has an annoying fault. When stationary or when driving the tailgate solenoid can be heard activating causing it too open. Ive tried disconnecting the interior elec release switch and also the exterior handle release switch but the fault still occurs. If i drive with the central locking locked it prevents the fault from occurring. I also noticed the red led on the drivers door flashes then stays on for 30 secs which according to the manual indicates a central locking fault. Any advice greatly appreciated and thank you in advance.
