Check, whether the ezs detect´s key insert. This you can do by diagnostic. Sometimes there is problem with microswitch. Maybe ezs was opened and the little copper lever falled out. And I had a vito ezs, there was no infrared activity at all, because hardware damage. I replaced the whole ezs and cloned data from old one.

I can confirm, had also one w639 key ok, dumps ok, microswitch ok, steering lock ok so i replaced ezs and all ok, car started.

Seems like this ezs suffers from hardware damage, didnt have time yet to take a closer look at the hardware to find out where the fault in ezs hardware is.

Yes you are right.
These are sometimes faulty.
Heating the microprocessors, is a part of the testing sequence.

Swap is the best solution.

Problem solved.

Switch modul defect.
I have swap from another eis (from w203) and all work well now.


Thanks for help
