I don't know if this helps? A MES scan from my gearbox on a 2017 twin egr 130bhp comfortmatic Ducato.
Edit: V32 software.

Thanks for that, currently laid up with Covid but as soon as I feel better I will compare those with my van, the results MSjoberg posted and those I got from my mates van to see if anything appears out of order.

Please how did you solve the problem? I have the same one.

End result was a leaking master cylinder which as it requires a gearbox/clutch drop I had both the clutch and master cylinder replaced at a cost of 1800 euros.

Thank you very much for your quick reply. Yes, it already makes sense. I replaced the clutch and seal on the slave piston in the clutch cylinder, there was sludge and vaseline that didn't belong there and that got into the dot4 fluid, someone had fixed it before. It's a Burstner Ducato Comfortmatic 2018, I haven't had it since the beginning. I am attaching a photo of the working cylinder of the clutch, in the second photo it has already been cleaned, on the left is the slave part, on the right is the metal master with the sensor. During the clutch electrovalve test, the error message is P2930-84-Automatically configured clutch engaged position - signal below the permitted range. So it looks like it will be a stuck or faulty master piston or EVO clutch solenoid. A sensor that is placed with the master piston and monitors its movement is probably not faulty. This claim of mine is supported by the finding that no dot 4 came out of the bleeder screw when venting with the Multiecuscan. Anyone have any other thoughts please?

I am attaching to help others who may need some information in pdf TEACHING GUIDE M40 ROBOTISED GEARBOX.

Please, can someone help me how to disassemble (remove) the master piston? I am attaching a photo.
