Hi guys ,i was asked to see a Merc 2010 GLK with posibile ESL failure .
The customer has 2 keys both work on remote but they do not unlock the eis.
Scanned both keys all ok ,but i noticed something interesting,ususal when i do a ESL emulator job ,if i put the key in ignition the little screen power on ,this time did not .
Tried calculating data for eis ,but at the last step CGDI says that the key is not insterted in EIS, tested the EIS coil with a tester and surprise ,is not being energised when the key is pushed in.
Measured the coil ,it has 3 windings , 2 of them are ~2 ohms and 1 in ~3 ohms so the coil is good.
From my point of view i think there is might be a switch failure ,the switch that pushes when the key is in ignition ,but i never repaired a w204/207 eis and i do not want to make some stupid thing before asking someone else opinion.
Has anyone of you a picture with that switch ? Where is it putted?Or did anyone of you faced this problem before? Thanks
