GL350CDI
Question GL350CDI

Good day

I have a GL350CDI (2013 model) with an intermittent ECO Start/Stop fault.
System works fine, but then at a stop street or robot, the engine stops(As normal), however when i do leave the brake and accelerate, the vehicle does not start up again( engine does not crank).I have to turn the ignition off and then start the vehicle manually. I did send it to the dealer numerous times for this issue, and they cannot replicate this fault. Fault code that keeps coming up is 16F400-The ECO start/stop function has detected excessively low engine speed. The dealer has replaced the Main battery twice, had the starter motor replaced and the software for the engine ECU is up to date. This problem is intermittent and is really frustrating for me. Please help
