w203 c220 cdi auto problem any thoughts
hi all my car cut out about 1 mile from putting fuel in.
engine light was on.
drove home in limp mode with it cutting out several times enroute.
runs ok when cold for 15-20 mins.
obd2 codes where-
P0087 low fuel rail pressure
P1470 EGR no flow detected
P0652 Sensor Reference Voltage "B" Circuit Low
P0192 Fuel Rail Pressure Sensor Circuit Low
P0193 Fuel Rail Pressure Sensor Circuit High
actions taken so far-
1-replaced fuel filter - (bosch)no change
2-replaced hp fuel pump(new) - was ok for 30 mins /no change
3-drained fuel from tank via filter to pump connection(flow good)then filled up with fresh-no change
problem still present when warmed up,cuts out just above tickover but you can catch the cut out with accelerator sometimes and rev past it.
needs star diag.suspect crankshaft/camshaft position sensor?
