Hi again, sorry for losing your time. I had the information from my client that they could not program the DME anymore, the limit of 12 was reached.
But it not the case; the DME can still be programmed 30 times but is in programming status 12. Every time they try to program it with ISTA/P, they
get the message 'Global Vehicle communication CoAPI.2084'. Something happened to this car, they had to replace the instrument cluster because it was
dead.
There is not much I can do with the tools (AH and Hextag)... Maybe I will try to see if it communicate in Boot mode...
