hello
I have a w220 : central locking is ok key goes inside the EZS and turn but no light in the dashbord and no ignition starting
It seems there is no ELV in the car ( original)
I tryed to chek the EZS 2155450508 with a profesionnal : he said it's working fine but still no light in the dash bord when turning the key

Can Anyone help me
Thank you very much for advance
