Hello,
Since a december I have trouble with  Panda sterring.  It happened 6 times !
They are well calibrated on the bench, they work. 
But while pluging on the car they don't work. and after returns the memory is crashed, I get wrong salues.
The battery is good. If I replace the steering without MES, it works.
So many questions  : 
- Does anybody have the same problem ? 
- Do you have an explanation ? 
- Is there a way to reset the steering software/memory?
Thank you for your help
