Hello together, if I open and close it by ZV (whether with remote control or directly at the lock), then open and close everything, except the tailgate. When I connect to the tailgate at the lock, everything goes. I have measured on the plug from the wire harness, which leads to the tailgate lock and then with the radio remote control open and connect. There then arrives at the pins 8-6 or 8-7 according to voltage. The contacts of plug and socket look ok. Contact spray ha I tried, but didn’t help. It’s funny that when I hit the plug, when it’s plugged into the engine from the rear flap lock, the ZV spins around. Speak up and close again, several times. Cable breaks or the like could not be recognized anywhere, everything looked fine. Before I buy the rear flap lock again on suspicion, can I test it somehow, or is it sure that it is? I had tried a motorcycle battery short power to the appropriate P to the (8 mass and 6 and 7 plus respectively), but the engine didn’t get excited either. Could be of course that this is not the right way to drive the engine? Would be very grateful about help! Greetings Johannes
