I need the part number of fuel rail pressure control valve
cause I have codes PO 087 & PO 088
and the work shop technician says that the valve which been installed is the wrong one as in the attached photo
Dear Sir
Thanks alot for your kind help , when I google this part no. it the part no. of the connector with 2 pins , the part no. of pressure control valve should be either
A 642 078 02 49
or
A 642 078 01 49
or another no. but same first 7 numbers
😶
waiting your kind urge
accept my greetings
thanks
M/B does not show that part # and you said earlier that you were told it was the wrong part.
the engine turned off after 80 km/h several times
the technician said because of the fuel rail pressure control valve
mine was with part no. A 642 078 02 49
I didn't find the same no.
I found A 642 078 01 49
when install it the engine turned off at 40 km/h
so they clean the old valve with some sepry cleaned and the engine work fine
I went to Bosch dealer in Irbil - Iraq he said that the installed part is not the original part no. for this engine but he couldn't give me the right P. No.
This problem is all caused by M/B. Instead of showing the part# at the end of the left fuel rail, they included it at the high pressure pump.
According to your vin# this is the part you need.
Dear Sir
A very good day to you
I google this p.no. found it's called fuel pressure regulator as pi pointed in yellow in the attached photo , so I understood that I have to change this part A 6420740284 not the pressure control valve A 6420780249
is this right ??

Today I removed this regulator found one of its side hole Clogged with something like mud
cleaned with sepry cleaner
hope this will fix the issue
Don't you see that the part # I pointed to is called a VALVE?
Yes Sir
it is
you see I became confused
here in Iraq there are no qualified workshop to deal with modern diagonal techniques
so I'm all ways get the right advise from you
