ML 270CDI engine problems

[pedro pires]

I have a ML270cdi for a year. It was pretty new but since 2 month ago I started to have engine problems.
When I was driving for a long period in a highway with high speed and I stop my ride for 5 minutes to rest, if I restart the engine and enter the highway again  in the 3th and 4th gear acellarating near 3000 rpm the engine fails power for 3 or 4 times then recovers
The car was already in Mercedes for 5 time they already change everything in the fuel injection system and the car remains the same.
Sometimes worse, entering in engine safe mode sometimes not, others the fail is kept in the computers sometimes not ,I don´t know what to do with the car anymore.
This car must have this kind of problems????????

Best Regards!

Hi Pedro,

Before any body can comment on your vehicle, the fault codes which should be stored in the ECU, need to be read and evaluated. Othere wise its guess work. Although I would of thought the dealers would of gone through all the usual test procedures.

Sorry I can't be of more help.
