Initial problem maybe is in to ESL (write with Ak400 k line and e.t.c) and formed secondary wrong ECU initialisation or faulty personalisation. Use DAS diagnosis, check drive authorization system and all actual parameters. All parameters in ECU drive authorisation need in "YES" status.

i will make virgin the esl and the ecu open dash

[Bembis]

But anyway - use DAS diagnosis :) and post here diagnostic logs (screen).

the ezs looks ok the esl works but i do not have ignition so am sure that the ecu has lost sychro .
Maybe the data of the key are wrong but i have check and it broacost ok

Replace EPROM and flash in ECU.

Yes, working. But with incorrect status. Check ECU personalisation after renew. If personalisation or other status is NO, the problem with lost synchronisation will repeat again.

bembis have right.you start from status check,after your check if all yes renew ecu and coded.you must change eny way K40 fusebox.it hapent one time same problem to me.cause K40 protect from not stable electric power.
