question w211 problem

What do you mean crank for 0.5 sec? if you hold the key to crank , does it start and die?

when i push start button ( is keyless go ) starter do just tick and stop, same and when i try to start with key not with start button, if i  start direct by relay the engine start. is not issue fuses

Look at ME varient coding and make sure tip start is “ein”

If you put all the original parts on the car...... all you need to do is virginize a used Engine module and performe initial start up.  Is that simple!  If you have done this, what issues are you facing???

yes mate i also did many times virginized ecu and programming on the car by initial start up. i know is simple,   i did that and 2 days ago, ecu personalized and active, get ori vin number ecc. . the problem is that the car doesn't crank ( STARTER RELAY JUST DO A TICK ONN FOR 0.5 SEC AND TURNED OFF) , i can start the car with a bridge to starter relay but i have transmission on limp mode that not change gears. so looks like immo block start and transmission

Mate, one by one. The fact that the engine does not start is by key is a priority, the fact that no command is getting to the coil side of the starter relay must be resolved. the coil of the starter relay gets power from circuit 87 relay and ME grounds the other side when start is commanded, have you looked at actual values in the ME under drive authorization? is start enabled?

no relay issue mate, because i have replaced relay, also with another kit ecu ezs ey, the car start but not drive because transmision is not programed to that ezs also new kit is not keyless go, other vin number

I am confused, you just said the vehicle won't start unless you jump the starter relay. So... did you solve that issue? does the vehicle start normally by the key now? as far as the other concern, best approach in my opinion is to renew the vgs and scn code online.
