Problem:
Citroen DS5 2.0 hdi DCM3.5 at 100% of writing i got this message with foxflash programmer, ecu dead, no communication on diagnosis. Any help??
Solution:
Sure is bad file . Recovery in boot.
Write in boot mode it will fix it.
Be careful with dcm 3.5 obd with all tools clone and genuine, sometimes write failed.
Better way on bdm.
