Hi All, not sure if anyone has had the same problem? after some diagnostics I purchased an EIS from mercedes thinking my Mercedes ML 320 CDi had an ignition starting problem I was getting no lights on the dashboard when turning the key! the new EIS was fitted and an attempt to code it along with the activation key was planned by a technician with the right Mercedes scanning and re-coding equipment. the technician has an issue as there is no communication with the EIS to be able to activate it when he connects his system to the car. its showing as having no communication to be able to read the new EIS has anyone else had this issue before? and if so what can it be
 
I know you have already bought the new EIS. But have you tried copying the old EIS to a used EIS unit?

I sent my EIS to a specialist who did this for me as I thought I had a EIS issue, it turned out to be something else.
 
Well that's interesting. The EIS is a Theft Relevant Part and at least last year Mercedes would not sell it to you - only allowed to be installed by their workshops.
It could be many things - including a blown fuse, broken wiring, broken EIS, wrong diagnostic tools etc etc - I don't know the age of your ML though.
