Did anyone ever get an answer for this "communication problem"? I've got a 406 2.2 HDi with the exact same communication problem, while clearing engine faults. I've searched everywhere for an answer, but I've only found a couple of forum-posts to the problem, but no answers.
I hope for a little help with my old HDi engine control unit
Best regards

Lexia gives Comms Error when clearing ECU faults

Re: Lexia gives Comms Error when clearing ECU faults
Does it still behave the same way if you select global test/all ECU's?
When I did mine I ran tests with the engine running then switched off for fault clearing, it won't allow fault clearing of the engine ECU while it's 'active'.
