Ok. I have a problem with my central locking on my 1992 e36 318. What happens is when I lock the car from the drivers door the car will lock but immedietly unlock itself unlocking all doors. So I then have to lock it again to lock the car. It then remains locked. I had a look at the drivers solenoid and it was abit worn so replaced the lock and solenoid but the problem persists. When I changed the lock I changed the slam panel that the lock locks to that holds the microswitch as I thought it may have been that but I still have the problem. Has anyone had this problem before? Im keen to fix it asap.
