Fuel Injection System

Fuel Injection System

Scenario

I was driving the other week on dual carriageway and on overtaking a car dash flashed up “Fuel Injection System” then completely shut down…..anyway managed to pull over and car restarted after ignition off to re-set, since then have driven very steadily and all ok…..

Anyway, I have INPA so hooked it up and got codes in three sections at same mileage, 4560 (3002) plausibility rail-pressure volume regulated, 4570 plausibility rail-pressure volume regulated, 4610 plausibility rail-pressure volume regulated.

Error Code

4560 Pressure Sensor – Plausibility – Pressure too Low
4570 Pressure not Plausible
4610 Rail pressure control valve adaptation
4c4f ?

Fix

Well since diesel fuel filter change, X5 is running well and has not had a repeat of the original fault of cutting out on acceleration due to low fuel rail pressure.

I did only just get around to cutting the old filter open and was in a poor way, the element was covered in a slimy or sticky oil type substance which I am certain would have restricted the diesel flow quite severely. On research it seems it could well have been asphaltenes, don’t know if this sounds familiar to anyone (would be interested to hear), but anyway I was sort of pleased as has given me somewhat confidence that this was the issue…..
