Hi, i have e250 cdi OM651 engine 2009
I had rough idle on cold with rpm jumping every few seconds by 50/100 rpm no errors or check engine light.Now i replaced the qcv on hp pump today with new one but after starting it it ran fine but after reving to 2k rpm eml came on, after reading codes i got P0088 pressure too high,P0252 quantity control valve electric fault
The car now runs good, accelerates a bit slower but no rpm jumping.
Dont know what else to do, after error delete it comes back after reving but drives normally, did the air got in system cause the valve was out of the high pressure pump whole night
before.
Can the new quantity c. valve be faulty cause i never had eml or high pressure error before?
Please if someone had some type of issue like this pls help.
Sry for english.
