KEYLESS GO NOT FUNCTION
Hi, I have a Mercedes Benz W166 ML350 BLUETEC 2012 year, the keyless go suddenly are not function at all, cant push button start, cant lock / unlock door by handle. I had scan with Xentry DIAGNOSTIC,but it cannot be read the data out from the keyless go control unit N69/5, it just show me the red word ' The control unit does not respond to the query from Xentry Diagnostics.' and below the red word ' Possible cause and remedies -The power supply of the control unit is not ok -The control unit is not standard equipment and for this reason it may not be installed. '
I also had check the fuse infront beside the engine and rear under the seat, that all are no problem.
Can you please help me how to fix it?
Sound like u have an aftermarket key fob I would love to see a pic of it if u have an aftermarket key fob the control unit and fuse are usually under steering wheel or the knee kick panel I only say aftermarket because to my knowledge that year mb didn't have remote start ....
How about the battery in the remote?
I have exactly the same problem. I want to replace the control module but do not know where it is located?? Under the rear seat or in the trunk under the spare??
