156 central locking problem
Like all alfa drives (or so it seems) I too have my electrical disturbance. It is as follows:
Sometimes, when trying to lock the car with my (factory fitted) remote, the central locking doesn't work. Not by using the remote on the key, but also not when turning the key in the acutal lock. The door locks, but only that door, and not all four, like it should work. So definitely not key related.
Solution: get back into the car, put the key in the ignition, turn it to acc-position and back, and take the key back out. Now everything works fine again. Happens about once a month. Anyone else with the same problem?
