My tailgate will only open on my 54 reg E61 if I use the button on the key. However I had a look at the wiring in the rear of the car, where the first aid kit lives. There is a single wire which seems to not connect to anything and it seems it has come loose from a circuit box. Could a single wire lead to the problems I have described?
Can any leccy be kind enough to supply an email address so I can forward a photo of the wire in question for their advise please?
Have a nice weekend people.
