  1. I broke down today and had to be recovered.
    i lost all electrics and rolled to a stop.
    management light is on and showing 10.2, 11.2, 12.2 and 37.4.
    has anyone had this before so I know before it goes into the garage?

    cheers
     
  2. yes it does thanks. look like it all to do with the earth to coil
     
  3. Electricity. You can’t see it, you can’t smell it but it can bite you is about as far as my knowledge goes. Andy

  4. I had an ongoing issue with vertical coil shorting to earth. Swapped coil, no joy. Was concerned about the ECU. In the meantime I serviced it and the issue hasn't come back since.
    Someone more knowledgeable will advise if a dodgy spark plug could actually cause this but new plugs seem to have sorted mine.
     
  5. The coils and injectors are all fed off the same relay. It’s a 2 quid part that should be part of everyone’s service regime.
