Twistedsanity Posted November 11, 2015 Report Share Posted November 11, 2015 Well after suffering with the usual DPF issues on my 2007 shogun and wasting my money on all kinds of fuel additives like wynns I have found a solution for all. It's a trade only product that of course is available on flea bay made by Wurth, it's an aerosol can of cleaner that is sprayed directly into the DPF through the temp/pressure sensor port before a spirited drive and enough smoke coming from the exhaust to put the red arrows to shame for around ten mins. Cost me £27 and as I was unable to get the rusted sensor out without causing damage I drilled a 5mm hole in the filter then sealed it up with a pop rivet and some gun gum exhaust paste, job done, problem solved.

Twistedsanity Posted November 13, 2015 Author Report Share Posted November 13, 2015 Not sure if it's relevant to all motors or just mitsi's but I found out as soon as the DPF light comes on the engine starts dumping in extra fuel through the exhaust valves when they open to get a hotter burn, we didn't bother going for an immediate drive to extinguish the light and though we would wait till the weekends now a good few occasions, I did an oil change last week (the first for 2 years as I've been busy and lazy) , clearly the fuel had made it into the oil as it smelled of diesel and instead of the usual 10l that it's supposed to have there was an extra 3 litres in there, the fact that it's still ok is testament to how strong jap engines are running with 30% more oil than its stated capacity, still no DPF light though :-) Quote Link to comment Share on other sites More sharing options...

Twistedsanity Posted November 13, 2015 Author Report Share Posted November 13, 2015 My friend is a service manager at a Honda dealership who reccomended the product, they have been using it for a few years now. I did also find out the the old "it'll cost a fortune to get replaced " isn't true anymore as there are plenty of aftermarket pattern parts out there now, the first place I looked at does a replacement dpf and fitting kit for £199 delivered Quote Link to comment Share on other sites More sharing options...

Do be aware that if the level gets high enough then the engine can suffer from a 'runaway', where it basically is burning the oil/diesel mix, and will rev to the limiter. As it does this, turning the key off will have no effect, as it will now be syphoning the oil/diesel mix up from the sump b y osmosis along the cylinder liners. It will continue to rev to the limit until the engine self-destructs - due to the lack of the oil which is has been burning for the last few minutes.

rodp Posted November 13, 2015 Report Share Posted November 13, 2015 If that ever happens rip the air intake pipe off and shove a board over the engine air intake, that'll stop it. Some will remember the Detroit 2 stroke diesel in bedford TM's, the emergency shut off was a steel plate over the air intake and a release cable in the cab. Boy, could those trucks fly, I've had both mirrors blow flat against the cab with the wind speed. ..................

Twistedsanity Posted November 13, 2015 Author Report Share Posted November 13, 2015 I Used to be a plant fitter and have seen an engine "diesel" on more than one occasion, it is pretty scary and a tennis ball in a tool kit to block the air Intake was standard for all the fitters Quote Link to comment Share on other sites More sharing options...
SpringDon Posted November 13, 2015 Report Share Posted November 13, 2015 My nephew in law (nieces husband) had his turbo go on the m42. The highway officer said he must move it off the motorway and the engine ran away on the hard shoulder . They all ran away and within seconds it grenaded itself spectacularly. It's quite scary if it goes. Quote Link to comment Share on other sites More sharing options...
al4x Posted November 13, 2015 Report Share Posted November 13, 2015 You can stall them if you have your wits about you stationary handbrake on and high gear and drop the clutch.... Done it twice over the years after watching a Megane go bang at maximum revs Quote Link to comment Share on other sites More sharing options...

Done it twice over the years after watching a Megane go bang at maximum revs Only problem there is you're faced with a choice : 1. Leave it be. engine goes bang 2. Try that. Clutch possibly goes bang. DMF possibly goes bang. Gearbox possibly goes bang. Engine possibly does NOT go bang. Devil's alternative, isn't it ...

steyrman Posted November 14, 2015 Report Share Posted November 14, 2015 Put too much oil in the engine once of my 1989 Nissan sunny (it was years ago) did the same thing high revs and would not turn off i stalled it by keeping my foot on the brake as i lifted the clutch drained some of the oil out the sump and drove it the smoke eventually cleared after a few miles Quote Link to comment Share on other sites More sharing options...

I know someone who had this happen in an auto,couldn`t get it out of drive,obviously wouldn`t switch off,he had to stand on the brake pedal both feet to slow it until it blew up ! Luckily ,he was on a straight ,quiet road otherwise it could easily have been a tradgedy. Quote Link to comment Share on other sites More sharing options...

Gordon R Posted December 8, 2015 Report Share Posted December 8, 2015 Yes. There are instructions - run it at say 1000 revs for 30 seconds - spray - 2000 revs for 30 seconds etc. Then drive it. The instructions are on the can. My son used a free sample from a rep on a low mileage diesel which clogged up with short journeys. Very impressive stuff.

Twistedsanity Posted December 9, 2015 Author Report Share Posted December 9, 2015 Spray it in from the "entrance" end of the dpf then Go for a drive afterwards, it will smoke like mad for ten mins once it gets warmed up where it clears all the muck out, still working well, no dpf light on since Quote Link to comment Share on other sites More sharing options...

Could be a different product your son used, you are suppose to remove the temp/pressure sensor to gain access to the dpf to spray it in which I imagine would be difficult with the engine running and the dpf hot ( and probably dangerous) due to the location of most dpf filters?
