2003 L322 auto diesel Vogue Stuck in Sports mode and will not start

I am hoping that someone out there could point me in the right direction and will be eternally grateful. Started with an airbag light on the dashboard and the front interior light not working. I put a diagnostic device on which said that the airbag had a fuse fault. Both issues started at the same time I think so guessed they might be the same fuse. So, I checked fuses that looked likely and they seemed Ok. Getting frustrated with that I then checked every fuse in the internal fuse box under the glove box and all appeared ok. Next day I went to start the car and I get a message on the dashboard saying sports mode and although everything that was working was still working, ignition lights come up etc, nothing happens when the key is turned to start. The diagnostics unit says that the engine is immobilised. I have tried a hard reset, charged the battery as it was also showing a low voltage and no improvement. The Gear selector can move up and down and shows PRND lights next to it. Has anybody any ideas or seen this issue before ?

Hello,
Sorry this is an old thread but my L322 has just done same as yours. Mine started with water in the AV kit, did same checking fuses, now I am stuck in sports mode, the gear selector moves and the LED changes but LCD just shows S, if I put it in S I can shift down and he LCD goes to 1 but won't go up or down from there. Car was in P when last turned off.

Just wonder what you did, I assume you got it sorted by now.
Thanks

OP's last post was Nov 2019 where they were saying they'd just bought a later L322.
Nothing to show what the result of the original question was & they don't appear to have had any answers/suggestions about it.
Hope you have better luck - and if you do find the solution please let us know!

I realised it was old just too much of a coincidence with the trouble I have. As it is an old post would it be appropriate for me to start a new thread?

Thanks

You'll probably get told off if you don't
