e350 cgi 2010 check engine

[Dany Al Khoury]

hello. I have a problem noone is able to fix. while driving my car starts lacking acceleration .it starts to break down and then the check engine pops up. i put it on the scanner it showed fault as .(the rail pressure is too high) No-1141. If i leave the car for a couple of hours and then drive it the check engine is still on but the car doesnt break down . sometimes if i leave it till next day or if i am standing in a down position and leave it for a couple of minutes . the check engine turns of. I have a e350 2010 mercedes aventgrade german car. someone told me the High pressure pump is not good. But if the high pressure isnt good it should not start the car at all . Please help me if possible. Thank you

Looks like a generic phone based app - try reading with a Mercedes specific code reader as the definition may vary from the generic.

When it's in a failed state check the live values of the crank sensor and fuel rail pressure.
