Year of Manufacture *: 2008
Engine Size and Code *: 1600
( Optional ) Scanner Used: Snap-on
( Optional) Fault Codes: P242F
On investigation, we found a faulty non genuine EGR valve fitted which we have replaced. The PAT fluid tank was found to be empty, so this has been refitted and adaptions reset.
The only code we are left with is P242F DPF ash accumulation. We have attempted to carry out a static DPF regen but it kicks us out before it even starts the regen. I've noted that the back pressure in the exhaust is high - 10 Kpa at idle and 73 Kpa when rev'd to 3000 rpm (maximum it'll rev to). This code will not clear and even returns before the engine is started. Oddly, live data reports 62139 miles until ash full??
My question is, if the exhaust pressure is reading that high, would that stop it from regenerating?
