    Check the transmission oil level first when COLD, as per the handbook/RAVE.

    Could also be battery related check the battery is fully charged

    Next step if both the above are ok is a diagnostic check with Faultmate/Autologic/Test Book.

    I have had "Gearbox Fault" up in the past and the car lacked "Pull", switched off the ignition and restarted without any fault message and ran fine for a week or more then went again......battery died shortly after, replaced battery and nothing since,

    Think I am just suffering from this, had gear box fault yesterday, lacked power as I returned home, struggled up my drive, turned over first thing this morning, gearbox fault warning, no lights on the displays, rev counter registered zero even when pushing accelerator, engine cut out every warning mesage the ecu know about flashed up and now the p38 wont start. Guessing the battery is dead awaiting Britannia recovery to come and sort it....

    Looks like a under bonnet fuse box issue.

    As Rick the Pick says, or bad earths. Pull the lid off the fuse box and have a sniff for burnt plastic.

    azzd - it was indeed the battery, completely dry, dead as a dead thing. held enough charge to start and that was it. Also turned out to be completely under spec'd. I have seen bigger batteries on a head torch :p
    Battery replaced and all working fine. Now just need to reset all the windows, sunroof, and work out which cable it is under the drivers seat which keeps setting off the airbag warning light as it is getting annoying now that everytime someone moves the seat the airbag srs light comes on.
