Radio Code Guru
I did something very similar Paul. Did some work on the front brakes on my daughter's Primera P12, did one side, got back in the car to turn the steering straight again, put the key in the ignition and it wouldn't turn/unlock the steering. Tried it about three times before I realised I was using the Micra key on my bunch of keys and not the Primera key, on her bunch, which was in the same pocketgetting ready for MOT tday, I connected the battery, IGN on and the engine light was flashing?
eh what's going on kasandra? crank, and doesn't fire up. oh wtf not now
checked for fault codes in datascan and shows "error code E1 & E6 after 2 starts"
sensors say the injectors simply not firing, Oh come on! there's no faults with any connectors, injectors, ecu etc etc
was almost about to abort the MOT when I then realised I've inserted the spare key when I was fixing the suspension
the master key was still in my pocket, used the proper key and wahey it fired up! Doh
