Hello
Owner of merc w211 e220 Cdi 2007
226k
I am having low fuel pressure issues.
Star diagnostic code 22e7
Check high pressure control ‘rail pressure too low’
When i open up the throttle (hard acceleration) going up a hill or on motorway, the engine light comes on and car goes into limp mode.
I used Star to check high pressure control, Quantity control valve, pressure regulator all sensors seem To be in working order.
I tested the low pressure circuit, fuel pump seems to be in working order.
Please i need some help.
