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....
