W211 fault code 2075-9

[whitefang]

Hi all, good morning.

I plug a w211 into a gernic scan tool. ( Not star)
It came with a code 2075-9 ..

Check system high pressure control.
Max pressure exceeded via quantity control valve.

Am I correct to say this is the fault on the rail at the beginning / part on the rail closest to the headlights, & not the bulk head.

Thanks all.

Hi all.
I just read my own thread, & cross checked a rail.
I found not sure if was a mb rail or a xx rail,but I seen ...
1 end by the bulk head is a ,rail pressure valve.
The other end at the head light side you have a, fuel pressure sensor.
&
From or on the hp pump is another a, quantity control valve.

I'm correct,? Please confirm / put us right.

If as I opened the thread 1st post, via quantity control valve, would this be my problem part.?

I presume the pump as this quantity control valve on...

The sensor is unlikely, s no code come back, & the rail pressure valve is unlikely aswell,.?

Ideas please...

Thanks a lot.
