I have a 2004 golf5 fsi 2.0 model. The car suddenly cannot switch on,if i try to lock the doors manually, only the drivers door locks. Central lock not working apparently. It started well this morning and i drove to work about 6km from my home and after i parked and tried to lock using immobilizer nothing happened. Key turns well in ignition but the car won't switch on nor start plus there areno lights on the dashboard, battery is ok. Please help..
The symptoms you describe would be exactly what I'd expect to see from a dead battery. I'd check the fuse cover ontop of the battery first plus the security of the battery terminal clamps.
