Yes! It recognize the VIN number and everything works well except for the Hydraulic presure parameter..kalm007 wrote: 14 Aug 2025, 22:23 There is very interesting because I use same software and I could measure the pressure of system.
When you use the diagbox and you select the car from the list. Is diagbox recognise your car or not?
That is, you do not type your vin number into diagbox, it recognise your vin number.

Re: Citroen Grand C4 Picasso 2012 MCP6 error
Yes! diagbox recognize the VIN number automatically, not sure why It doesn’t allow me to see hydraulic pressure parameter live. At this point I am very convinced that this is a issue with a sensor or something related, because I can understand that the maybe the pressure is low in the system, but why it is not requesting to reduce the torque when it’s changing gears. Also I’ve noticed that the steering wheel module has logged the C1210 error, which according to my investigation can be related to a torque measure issue. But I can’t find how can I solve this issue..kalm007 wrote: 14 Aug 2025, 22:23 There is very interesting because I use same software and I could measure the pressure of system.

I think you have to use fewer torque. Because full torque is not so good for the transmission. And if you use fewer torque. Is there causes slipping in this case or only with full torque.
And can you take a picture what is the problem when you would like to mease the pressureof system. There is very imortant that the car can keep the 50 bar pressure.

The issue with the slow clutch is there no matter how much torque I apply, I can do go very slow and accelerete very slowly, and the clutch takes a lot of time anyways..I would take a picture, the issue is that I am not with the car right now..anyways I don’t think that would help tonsolve the issue, the ecu does not allow to seee that parameter, I so have to figure out how to solve the issue without it..

This is the message I get when I try to measure the pressure live..kalm007 wrote: 17 Aug 2025, 00:03 I think you have to use fewer torque. Because full torque is not so good for the transmission. And if you use fewer torque. Is there causes slipping in this case or only with full torque.

You may like to edit your post and mask the VIN which is displayed on the screen. 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Re: Citroen Grand C4 Picasso 2012 MCP6 error
Hi, I have exactly the same problem. The launches are fine, but between gear shifts the control unit doesn’t reduce the throttle, it revs up to high RPMs and I have to wait a long time before it shifts into gear. It’s only really drivable in manual mode. The worst part is that the clutch kit is brand new, the transmission software is updated to the latest version, and it still does it.
Could you please advise me on how you solved your problem? I’d appreciate any advice. Thanks for your reply.

Hi! Have you checked the accelerometer values in diaxbox?In my case it has fixed values: 2,7 m/s of transversal acceleration, 27 degrees of angular speed while the car is not moving, and also the steering weel angle sensor is reporting 60 degrees with straight wheels. please check those numbers and let me know if you have the same issue, thanks!Mazus0909200_ wrote: 23 May 2026, 07:56 Hi, I have exactly the same problem.
