my central locking has gone recently on my 91 gti, i have to use the key in the drivers lock to open the door instead of using my remote on my alarm,the thing is when turning the key in the drivers lock the passengers side lock wont open and to close it you have to close it from the outside with the key in the lock or from inside by pushing the pin down, but the most annoying thing is when you first get you you can hear the rear hatch pump making a noise and the boot wont open from the outside either then after about 2 mins it will stop making the noise- and still not open, help!!! all this CL lark is driving me mad what do i do?
