Hi have a 2005 astra.
One day the tailgate would not close and kept slamming it down a few times and eventually it worked.
The next morning when you get in the car as soon as you open the door you get the beep beep chime sound until the door is closed. same when you get out etc.
The central locking no longer works.. have to lock the drivers door but all the rest do not lock, even with the key in the driver door or by the keyfob.. i have checked the fuse for this and its ok..
now to complicate things, last night it started working! and now again its stopped working... any ideas?!
