2.0 L Petrol 2004.
After trying to start the car with a flat battery, I remove the battery to charge up then replaced it back in the car. Now with ignition turned on the BSM Delphi fuse box under the bonnet makes a horrible buzzing sound and the display in the car shows "Imobilizer Fault". Turning the key to start the starter motor does nothing.
Prior to this the car was fine, even if i removed the battery.
Whats happened ? and How do i fix this problem, BSM fuse box faulty ??? cheers.
