Hi all, new to this but thought you guys might be able to help, I have a 2000 X Reg Multipla that has a fault. When you press the alarm button the alarm activates just fine, but the central locking has stopped locking the doors. It doesn't lock any of them....any ideas?? Also the little lcd screen where the mileage and tempreture is displays comes on and gos off randomly, light stays on but the info disappears....
