    My first guess would be that it thinks it's in gear.

    Any particular reason why it might think that? or what could i do to check it.

    When i bought the car the fella said he had starting issues sometimes and apparently one of the fuses that are underneath the drivers carpet needed to be replaced. Wonder is there any truth to that? Haven't had any starting issues what so ever in my ownership so haven't even looked into it. Sickened now cause it happened at the worst possible time :@

    When the car starts I would imagine it requests a boolean status from the transmission control system, it looks like it's requesting something that's failing to respond, it's assuming a fault and without communication from the gearbox, is assuming it's in gear.

    Just a thought, could be wrong

    Went to the car this morning and it starts now every time no problem. Want to figure out what caused it now before it happens again.

    Hmmm, something is still up with it. Went to a petrol station to get diesel, wouldn't start again twice, and on 3rd time started no problem. Been grand again since then. No codes coming up on the diagnostics now after clearing them last night.
