D5 diesel fuel consumption

[galloot633]

Could someone point me in the right direct with an issue I’m having with my 06 xc90 . About a month ago I started getting the “ soot filter full “ message . Here’s what I’ve found , with the MPG display in instantaneous, when I accelerate the MPG drops to around 8 MPG and stays there even when I stop accelerating or to the filter blocked message comes on , however if I lift my foot off for a second then put it back the MPG starts climbing to its usual MPG , I have not idea when it comes to diesels, so any ideas would be appreciated

when you get the SOOT FILTER FULL message it is not necessarily a fault, It is advising you to go out on the road at 50 - 60 mph for about 10 miles to enable the soot to burn out.. I would guess you have been pottering around town for a few weeks. so this "regeneration" can't occur...

Thanks clan , I’ve took the car on the motorway to clear the message , but it soon comes back because of this “ overfueling “ problem I have when I accelerate, if I’m extremely gentle on the throttle , no problem but normal accelerating sees the MPG stay at 5 untill I take my foot off

I dont know if you have read this post

usually a injector plug repair kit cures this... with the movement of the injector wires going into the plug due to vibrations it wears the terminal.

Thanks Clan , I’ll look into that , would that fault explain the reluctant starting and the DPF self cleaning then blocking a gain in about 10 miles ?

Maybe but there should be a specific code about the DPF if that process is faulty. Best get your 1st fault cured first 👍
