    Not selecting - Auto or Reverse. PLEASE HELP

    Hi,

    Iím having an issue with the gearbox, when the ignition is on - the car does not go into auto or reverse.
    On the dash, it just displays neutral.

    I disconnected the battery for half an hour and reconnected it. Before I turn the engine on, the car will go into Auto and Reverse. I hear the clutch actuator move and the dashboard displays A, N and R accordingly.

    However as soon as I start the car, the problem occurs and it stays in Neutral.

    Any suggestions on what could be causing this?

    Ha, no itís not that.

    Iíve read somewhere it could need a gearbox firmware update, has anyone had any experience of this?

    Iíve also been told the clutch could have gone, but if that were the case, why does it seems to work when the engine isnít running?

    You could try forcing a gearbox reteach.

    Foot on footbrake and hold it there, turn the ignition on. After 30 seconds or so you shoudl hear the gearbox clunking and whirring along with three horizontal lines on the dash. It will not fix the need for a gearbox firmware update but it is possible it just forgot where it was.

    The gear change N, A, N, R sequence will still work when the clutch is knackered and the engine is not running.

    Thanks for the replies.

    Yes itís a 451 CDI.

    Iíll try the gearbox reteach, but if that doesnít solve it and it is the clutch/broken centralising finger spring, how difficult would this be as a DIY job?

    Iíve done a fair bit on cars before but havenít removed a gearbox and replaced a clutch before. But it is something I would enjoy learning to do.

    I don't think I have heard of a CDI breaking the pressure plate. Remember it is a completely different beast to the 451 petrol, more like the 450 petrol than the 451.

    Thanks,

    I'm hoping I don't have to replace the clutch just yet.

    Is it possible that I just need to adjust the clutch actuator?

    Can anyone please tell me how that is done? It would be much appreciated.

    You need a diagnostic device that will do it.

    Hi,

    I thought the diagnostic device (eg Star) would adjust the clutch, not the actuator.

    I thought the actuator is adjusted manually?
