I have a problem with the central locking on my 2000 318i se. The doors will lock using the remote key but will not unlock. If I put the key in the keyhole the same thing happens... it will lock but wont unlock except the drivers door.
When I press unlock on the key fob the interior lights come on but the doors don't open. Also, the button on the centre console does the same thing, it will lock but not unlock. The remote opens the boot ok.
I have been told that it is probably the ECU located behind the glovebox. Does anyone else have the same problem? How much would a second hand ECU cost? & would I be right in saying that the ECU has to be programmed to the car by a BMW specialist?
Any help would be appriciated... it can be very emabarrasing when the wife and kids have to jump over the seats to get out of the drivers door because the other 3 doors wont open!!!!
