Default W211 - check component R39/1 and Rail pressure to high
hello
i have an engine check light and after diagnose i found
W211 - check component R39/1 and Rail pressure to high
hte 39/1 seemed ok after measurement
but the second problem is not clear
I changed the Y94 quantity control valve but today just appeared again the check light
tomorrow I will replace it back to mine and change the Y74 pressure regulator valve, let's see ?!?!
the fuel tank was at 1/4 now i refilled it to 3/4
the oil and filters had almost time to be replaced, maybe they are influencing it?
still I am doubtful for the injectors because another mechanic was saying the injectors can also cause high pressure on the rail
I think the injectors can cause low pressure and not high ??? right ???
thanks
