Renault premiums.(Help appreciated)

Hi All.Im looking for some advice.I have got 2 Renault premiums in the workshop at the moment and could do with some technical help.
The first one has warning keeps coming up on dash Clutch piloting error.I replaced valve on side of gearbox and it cured it for a few hours then warning came back.

The second one has warning on dash saying Auto workshop stop and it sometimes won’t select any gears.
Thanks in advance.

I can’t help you as not a lorry mechanic but found this re “auto workshop stop”. Maybe helps? I don’t know. Worth a try

4th post down seems closest to your message you had. Something about a heavy load on the air bags tripping it, with a reset suggested. Again, I’m no lorry mechanic, worth a punt.
