M157 fuel pump quanity control valve 0 under 1500 rpm
Hi there,
I have had a 63 for about 6 months and its driving me crazy, its coming up with a p0088 high pressure if fuel system.
Only fault i can find on xentry is the left quanity control valve is showing 0 under 1500rpm which it should be above 20 on idle. As you rev it up it will go to the required amount of 20.
I have had the the both fuel pumps left and right changed but that hasnt worked.
any ideas would be much appreciated to help get this sorted
