Right, last night i disconnected the battery. Today, i connected the battery and nothing changed. Then i disconnect both plugs on the gearbox ecu, they looked fine so i reconnected them. Then i turned the ignition on and it started! Went for a 10 mile drive and drove perfectly!! Got back, switched it off and tried it 4 hours later, and it was fine. Went to drive it home 20 mins later and it noting. The dash says no gear or N isnt selected. And wont start... Rescanned it and the clutch position fault is still there
