unofix Posted August 15 Share Posted August 15 I don't like ......... Static Regen Failed (twice) My daughters 2010 Kuga with just under 60,000 miles has once again been kicking off about the DPF. I thought it was a sensor fault but after 3 replacements in under two years, it looks like the actual DPF soot levels are just too high. I used FORScan today to do a static regen (takes 50 minutes and drinks diesel like it's going out of fashion). It failed at 61% of the cycle, but offered me the opportunity to repeat it. Sadly the second attempt was no better. Any suggestions for cleaning the DPF ? 馃 1 1 Quote Link to comment Share on other sites More sharing options...

If it is just Ash and it is easy to remove then you could try cleaning it with running water, but it may not work. 1 Quote Link to comment Share on other sites More sharing options...

If it uses a vapouriser, I'd check that if the blockage is caused by soot. However...the DPF on the 2.0 TDCI is straight through.聽 You could try back-flushing it with a hose after removal.聽 Just be aware that if you leave any wet ash inside, it will set rock solid like concrete when it dries. 1 1 Quote Link to comment Share on other sites More sharing options...

It depends what task they're claiming to complete.聽 If you pour it into the tank, then no, it doesn't do anything.聽 If the DPF is blocked with ash then again, it won't do anything. But if it's blocked with impacted soot (unable to catch light without oxygen getting in between), and you can spray it directly onto the soot, then yes, it will break that down, like burnt carbon deposits on an oven or grill.聽 Once it's been broken down, it can then be burnt through regen as normal. 1 1 Quote Link to comment Share on other sites More sharing options...

Any suggestions for cleaning the DPF ? 馃 Plan a route where you can cruise at 60+MPH, constantly for at least 10 minutes, probably at night Get the vehicle warm for at least 20 minutes, good battery, plenty of fuel Hold the revs at 3,800 RPM constantly for 10 minutes (normally about 3rd gear 60+MPH) Every couple of minutes or so, dump the clutch and full throttle up to the rev limiter and hold it there for about 10 seconds, lift clutch and carry on at 3,800 RPM That will clear it out 1 Quote Link to comment Share on other sites More sharing options...

Just do a kickdown every so often so that it revs fully, try and hold the gears if you can 1 Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted August 16 Share Posted August 16 Probably best to put in sports mode to hold the gears longer. Or you could always try shifting into R for race mode. 聽 2 Quote Link to comment Share on other sites More sharing options...

Tizer Posted August 16 Share Posted August 16 I agree with what Tom and Dave have said, and it is strange that the Static Regen is being aborted part way through though. Unfortunately FORScan will not tell you why, whether the DPF is not getting hot enough, if there is a fault with the Vaporiser, if it is too clogged up or some other parameter is not right. If you do another Regeneration it would be a good Idea to connect FORScan up immediately after the Regen has been aborted and check the DPF Temperature, I would expect it to be over 500 C during a Regeneration and falling sharply with a running engine afterwards. If the DPF was too clogged up then I would expect that the Static Regen would not be allowed to even start for safety reasons. FORScan should be able to tell you if the Electrical side of the Vaporiser is ok and I believe that if you disconnect the Fuel Supply you can blow down it to check if that side of things is blocked. If you do a Dynamic Regen then it would be a good Idea to Live Monitor the DPF Temperature and Differential Pressure to see if a Regeneration has been triggered and what sort of Differential Pressure is being shown when driving and at Idle and before and after the Regeneration. Assuming that the Vaporiser is working ok then my gut feeling is that the DPF is either full of Ash, which can't be burned off or has partially melted. 1 Quote Link to comment Share on other sites More sharing options...
DaveT70 Posted August 16 Share Posted August 16 Regen may not be set up properly for auto, maybe? You could try contacting Forscan, with logs, they may be able to see why it isn't completing and sort it for you 1 Quote Link to comment Share on other sites More sharing options...
