w203 EZS infrared

[labusas]

Good day,
Please advise if you know how to repair EZS on w203 2005. It passes diagnosys via OBD but no power via infrared with infrared reader key or with EZS tool (LED is not ON). Key is checked good.
Is it infamous micro switch problem or coil inside?
Thanks mates.

I once had similar problem with w211 or w209 ezs , wrote new flash(not even from the same ezs part number) and started working.
