Wrong steering wheel & Yaw/acceleration sensor values

Hi, I’m struggle with an issue with my cmp / mp6 gearbox on my Citroen C4 1.6 hdi 2008. Basically it operates the clutch as it is always in 1st gear (slow clutch release with no toque reduce request). I’ve tried everything on related to the robot, new clutch, replaced hydraulic group, checked cables, everything! But the issue seems to be somewhere else, because I noticed with Diagbox that it’s the TCU the one that it’s operating the clutch that way (you can see that when you compare the clutch position and the clutch position refence). i’ve tried with another TCU as well, nothing changed. So I started to dig in another systems, I suspect this is related to a sensor, so that’s when I discover that the steering wheel angle sensor, the Yaw and acceleration measures are wrong.
When I am parked, Yaw angle shows 27 degrees/s, transversal acceleration is 2,5 m/s2 and also longitudinal acceleration never goes higher than 0,2 m/s2 (even when I fully press the accelerator). I’ve disconected this sensor, and here it comes the craziest thing: diagbox still shows some longitudinal acceleration when the car moves!! I also measured pin 2= 2,31v and pin 3= 2,59v.
Related to the steering wheel sensor, it shows 60 degrees when the steering wheel is straight, I’ve tried to calibrate ir several times, but always with the same result..
I don’t know if this can be the problem with the gearbox, but it’s definetelty not right!
Anyone has experience with this kind of issue?

Thanks for your response, I’ve checked the post and it seems like this is not my case as I don’t have any melted fuse or even any DTC reported..
