I have a problem with Mercedes, I put the ignition on, the fans start working
Car not start fault code in instrument B1102 CAN with engine system Engine system without fault code.

What caused the car to stop starting? Could it be a slow battery drain? Maybe there was an unsuccessful attempt to reprogram the ECU? Gearbox manual or automatic? What scanner do you use to diagnose?

[mercis]

if fan run,ecu death or no power

[marjan76]

The car has a manual transmission
when I turn on the ignition 3-5 times, I can start the car
the computer has not been reprogrammed

[mercis]

for test make ecu hot and test,after same cold

[marjan76]

hot ECU not start
Cold ecu start soon

[meser75]

Does the starter always turn? Is the booster pump installed in the fuel tank on this model? What is the pressure in the fuel rail when the engine is cranking? What is the pressure regulator current?

[mercis]

test with donor ecu,this type must often reballing

[marjan76]

I also think the ECU is bad
