Total electrical power loss when key turned to start position
Hi all, had a bit of a problem today going to go out for a drive unlocked the door with the remote got in the car and put the key in the ignition, turned to posn 1 all lights came on etc turned key to start engine, the engine turned and just started then stopped and all power went off radio, lights, central locking nothing working at all except the fuel guage and rev counter remained in running positions.
Turned key back and removed it, refitted and turned, nothing.
Tried spare key, nothing, rev counter still at 1500 engine not running.
Opened bonnet and checked all fuses, all ok, checked the black and yellow relays at the back of the fusebox these ok also.
Checked the battery terminal, ok with no corrosion nothing loose.
checked battery voltage showing 12.1v so put trickle charger on.
Opened up the relay compartment and checked for water loose wires etc could not find a thing. Took the plastic plug out if the door keyway and manually locked the door.
Left it for a couple of hours went back, door unlocked with the remote again, inserted key in the ignition and turned to posn 1 all lights etc came on, turned key engine started all lights except BAS/ESP went out.
Had a read of handbook that said turn wheels full lock to full lock then back and lights should go out.
Started the engine turned wheels full lock to full lock, was a ping sound and lights went out.
All things working again what could have caused the problem ?, the only thing I have done different is separate the keys and use what looks like the better of the two keys.
Back to two keys fastened togeter on one key ring untill i know a bit more about the car.
