DPF Warning Message
 

New here, thanks for having me. I'm a novice Volvo owner, having bought my first, a 2008 XC70 D5 less than 3 years ago. This morning, on my drive to work, the dreaded Soot Filter Full see manual warning came up. I kept driving, and the message stayed there for about 10 minutes. Just before my journey ended (my commute is about 20 minutes) the warning disappeared, and it hasn't come back. My question is, should I go for good highway run at 100kph for half an hour to give the DPF a cleanout? My normal work commute involves a short run home along a highway at 100kph (in case you guys in the UK don't know, we in Australia have been fully metric for nearly 50 years, unlike your half hearted effort lol) but only for about 5-10 minutes. The car wasn't used for 3 days over Easter (we can't go anywhere or visit anyone during this pandemic) but yesterday I went for a long drive around our beautiful Swan River, but never going over 70kph. My car has done 128,000 kilometers.

The yellow soot filter full comes up when the DPF gets to a certain limit (full). What you should do is continue to drive until it clears (as you did). It should have regen'd itself and may be perfectly fine.

Short journeys are always the problem.

It may also be the beginning of bigger issues, but maybe not.

If you get the message again, keep driving, the worst thing you can do is stop and turn it off. The message is basically the car telling you the DPF has too much in it and it must be burnt off now, so drive me till I burn it off.

If you don't, i'll get more full and will eventually go into limp mode.

If you have a nice friend with VIDA/DICE they can read the car and tell you how much soot is in the filter. Very handy!!

You can also use a smartphone and Car Scanner Elm Obd2 app.
It will tell you the DPF soot level, and quite a few other useful parameters.
