Volvo 2.4 D5 random stalling/cutting out (euro 3)
My V70 D5 Euro 3 has been randomly cutting out. Fuel filter replaced, no change.
Symptoms - Occuring once engine is at operating temperature. - Engine randomly dies at low speeds or just after pressing the clutch. - Engine randomly dies when touching accelerator after short spell of sitting at idle speed. - Engine WILL NOT restart unless you turn the key to position zero first. Cause/Fix Bad connection on the plug for the Fuel Rail Pressure Sensor (left side of fuel rail), which i suspect was causing excessive fuel pressure readings at idle, causing the ECU to shutdown the fuel supply. For perspective, once up to temperature, the car was cutting out 2-3 times per journey on every single journey without fail unless I actively held the revs at a higher rpm than idle, so seems to me the idle fuel pressure reading was the cause (though I never checked this with VIDA, but is what I suspect). I will also say that my vehicle is very high mileage and has had MANY issues caused by bad connections e.g headlight stopped working. Some lights on center console stopped working, Starter Motor stopped working. All issues fixed by cleaning the electric terminals/ensuring good connection. I would say that if you intend to run these cars into high mileage then check your electrical connections before rushing out to replace expensive components.
