DPF - happy ending


After a couple of years of mostly town driving ( my 2006 159 on 136,000) we went to the "get engine checked" dashboard warning message and thereafter into limp home mode.

Fault code P2002 - blocked DPF. You know the story....

Unplugging the MAF overrided (if thats a proper word) the rev limiter to get home and after 2 days of clearing the code every hour or so with a 35 quid draper code reader to temp disable the limp mode, I tonight report the following fix..................

Wynnns DPF cleaner added (7.50 with me trade card at Hafords) to a half a tank of asdas finest diesel - but problem was that it wouldn't run on m/way for long enough to regen with the MAF sensor connected before dropping back into limp.

After x3 resets (code clearances) I then disconnected the MAF and sat at 4000 rpm 70/80 mph on M23 in 3rd gear for 20 mins and went from Brighton M23 to M25. MPG reading went up n down so i successfully provoked a regen,

Reconnected the MAF sensor plug at M25 and drove back home - and all is now well.
Obs DPF is on the way out but so far so good and I guess I will be in the market for a 2' masonry drill in not too distant future ?

Hope this post makes sense and helps someone in similar situation.

Do ask me any questions if you have them....

Personally, I'd use Archoil AR6500 DPF/Cat cleaner rather than Wynns, but glad ya got it regen'd ok.

I will look that up,

Intend to use the wynns (or similar) on a regular basis as its likey the DPF is on its last legs.

If it does give up I will try the drilling to out "fix".
