Right, yesterday I was driving my car, all was fine no problems at all. Stopped at my mates to pick him up and tried to start my car again and all I got was clicking from the starter, bumped the car last night and managed to get it home however the needles were going mad, had loadsa fault lights pop up and the EML came on too, left the battery off last night and just been out to try and start it and I got nothing. Relay clicks to fire the starter but doesn't engage, but now I have keycode light on and it doesn't go off, tbh I'm stumped!

Are you saying the starter doesn't turn over, or do you just get a clicking noise from the starter?
 
The keycode error light coming on could have something to do with the starter refusing to work as well.

Needles going crazy, warning lights popping up everywhere and an engine management light would indicate to me either a new starter battery, or the engine control unit has died. Just my 2 cents anyway.

Andy any ideas in how to soft reset the ecu? I remember they did it when I had it remapped, resetting all the nodes of the can bus systems
 
Fitted another battery that I know is good, still keycode light on
 
That does nothing lol, starting to annoy me now stupid POS car
 
dash aint been out dave, if the ecu is removed/unplugged does it not need a reset to switch the keycode light off?

when it was mapped it involved random clutch pumping lol
