MY ML270 SUDDENLY STOPPED RUNING WHEN ON ROAD AND THE EPC LIGHT CAME OVER. AFTER STOPPING IT, I REMOVED THE KEY FROM THE IGNITION AND STARTED IT AGAIN AND WAS RUNING GOOD TILL NOW. WHAT WOULD BE THE PROBLEM? IS THERE ANY IDEIA ABOUT POSSIBLE SOLUTION? PLEASE HELP!
Hello The
engine and the automatic transmission in this vehicle are computer
controlled and in most cases when a fault occurs a fault code is
stored in the memory of the computer control module. There are
exception to this, such as the Mass Airflow Meter and fuel pressure
problems. What must be done is to have all the basic testing done
such as a scan of the system for fault codes as well as a check with
a live data scanner tool for engine functions that are not within
range of normal, a trained technician is required to know what is
correct and what isn't, then based on careful diagnostics done from
a factory repair manual the correct part is replaced or the wiring
repaired or the computer replaced (known as the PCM), which is very
rarely the problem. Other basic checks must be done as well such as
mechanical problems with the engine as well as engine state of tune
and mileage on the engine. The transmission can have mechanical
issues as well such as no gear engagement at all or a failed pump or
other pressure related problems.

Hi ,
You need to get the codes read as there are so many possibilities,best to use dealer level diagnostic equipment.
Testimonial: "thanks mate very helpful, can you tell me if a second hand ecu can be reprogrammedand. the mercedes fault codes are:- P1190 - 128 : Y74 N3/9 "
SOURCE: Same thing happened to me!
your crankshaft positon sensor is defective. Replace it and the epc will never come back and no more dying out. this happened to me several times and it would just come and go. i replaced it and now the car starts right away and the epc light hasnt returned since

Tell him to clean the electrical connector at the throttle body with 90% rubbing alcohol. He may want to use a nylon brush on the contact pins while cleaning. I'm pretty sure the car needs a throttle adaptation performed also. Find a shop with a Vag Com scanner, they can do it for you.
