This all happened at once, car was perfect then windows, sunroof and remote locking stopped working. I've been googling and searching but have yet to find something displaying these exact symptoms;
- Central locking no longer works, indicators don't flash, it's like I havent even pressed the button on the key fob.
- Electric windows and sunroof don't work - again just dead.
- If I lock with the key, the alarm does arm - ie. flashing red LED on the door
- If I press the lock button on the driver door nothing happens, no motor noise from the central locking pump.
VCDS shows a central locking pump leak and nothing else, I've cleared this and it comes back straight away.
Is this simply a case of replace the central locking pump (as it contains the convenience ECU which controls windows/sunroof as well)? OR is this a wiring issue somewhere as it almost seems like the central locking pump is getting no power or is dead? (I've checked fuses).
Also, I checked the pump and theres no water or obvious damage around it. Hoses and wiring appear fine.
Apologies for the long post, really hope someone can point me in the right direction - is it worth replacing the central locking pump first?
