No Start, all looks OK but wont crank
 

I have a W222 2015

Today I went to start it and it does not crank, does not click, dash lights do not dim.

Key moves all the way as it should

I checked in Xentry, all relevant units have DAS Start authorization

All circuits are on except circuit 50 (ignition). When I turn the key to crank, circuit 50 jumps to ON

Xentry is zhowing zero errors. Would appreciate any advice to help pinpoint,

I switched out the starter relay, made no difference. I have the wiring diagrams, all fuses seem OK.

Based on what you said if its possible I think I would be inclined to try to run jumper wires to the starter and see if it works......

SOLVED
 

Have solved it.

Found another fuse. Initially I checked Fuse 111 which runs to the starter solenoid.

Then I checked the circuit diagram and found another fuse (129) which is just before the starter relay, turns out that was the culprit

Fuse diagram attached, hope this helps someone in future

Good to hear you got it fixed , I thought it was a battery related issue
