Lemon Posted September 25, 2016 Share Posted September 25, 2016 Hello wonder if anyone can help. I recently bought a 2010 Outback Diesel. now the DPF light has come on a few times and I have cleared it following the procedure in the hand book, but today whilst driving back from Perth to my place in Braemar, the light is now flashing. I was driving fairly quickly on this road, so engine was up to temp. Does this sound like the DPF needs clearing? any ideas how to rectify this? Is it a dealer only DPF regeneration? Nearest dealer think is 1 hour 15 away :-( can a local garage handle these regenerations? any help here would be great thanks Lee Quote Link to comment Share on other sites More sharing options...
stuartie Posted September 26, 2016 Share Posted September 26, 2016 Hiya lee unfortunetly i dont have any experience with the outback diesel but do work on diesel engines and by the sound of it it looks as if the dpf could be starting to get blocked which your local garage should be able to re-gen if the have decent software to read the ecu, also they will have to change the engine oil and filter afterwards as when the re-gen is being carried out the ecu chucks tons of fuel in to clean out the dpf which gets into the oil and thins it out and basically fills the sump so its really important to get that changed straight after the dpf has been cleared, hope this helps buddy ☺ Quote Link to comment Share on other sites More sharing options...

W444AJD Posted September 27, 2016 Share Posted September 27, 2016 I would put a bottle of DPF cleaner in the fuel tank ASAP and give it a decent run, something like Forte. That helped with my last car which had a DPF. Quote Link to comment Share on other sites More sharing options...
donnylad Posted September 27, 2016 Share Posted September 27, 2016 DPF's are a total pain in the !Removed!, get it gutted IMO, I did this on my bmw and never had 1 problem! Quote Link to comment Share on other sites More sharing options...
DPFCleaned Posted September 28, 2016 Share Posted September 28, 2016 Hi , There is a lot of talk on the forums about getting the car to Regen in order to get rid of the DPF lights / message showing on the dashboard. In order to fix this problem effectively and as economically as possible , it is important to understand exactly what has happened with your DPF . The DPF will regenerate when the right conditions are met based on a number of factors and this happens a lot more often than you might think , The DPF lights or message will start to appear when the vehicle is struggling to perform a effective regeneration , Taking it to a garage and asking them to get the car to do a forced regeneration is pointless and a waste of money as the car is already trying to do the same thing and failing (hence the error message / lights). The only time you can overcome this problem is when the DPF is not being asked to perform a regeneration due to a faulty sensor (exhaust temperature sensor , differential pressure sensor , Vaporiser ) or some other component directly related to the DPF .Then you can replace the faulty component and ask the car to do a forced regeneration. However you need to bear in mind that most of the time a Differential pressure sensor fault is caused by the blocked DPF as the sensor pipes are also clogged. During the the normal operation of a DPF it will trap soot which it will vaporise during regeneration , as a byproduct of the soot being vaporised a small amount of residue is created which is ash , this ash has nowhere to go and starts to collect in the DPF , as time goes on the amount of ash in the DPF increases and the space available for the soot to collect before being vaporised decreases , this results in the car trying to perform regenerations with increasing frequency and results in the oil level going up due to the excess fuel making its way back into the sump. The only real solution is to get the DPF cleaned out or gutted , Given that gutting the DPF is illegal / harmful to the environment and wont help you get an MOT then it really is an inappropriate choice unless you dont really care about anyone except yourself. There are a lot of choices available when it come to cleaning the DPF and range from cheap chinese ultrasonic machines to Professional level Italian Flash machines. The Flash machine is the best way forward as it is a straight forward solution which makes sense and with flushing at 3-10 Bar it is guaranteed to unblock even the most stubborn blockage , you can watch the flash machine in a Video on youtube , or you can go to our website for more information. Good luck and let us know how you get on. 1 Quote Link to comment Share on other sites More sharing options...
Sam B Posted October 11 Share Posted October 11 Orange DPF light flashing on dash = Oil dilution >10% = change engine oil with fresh oil (too much Diesel in the Engine oil increases Engine wear Solid Orange DPF light on dash = Blocked DPF and car will go into limp mode = forced regen or DPF wash / clean out = best to get a mechanic to do this unless you know what you are doing. Tip - change engine oil every 5000Km and RESET the Oil Dilution monitor to zero (search online how to reset) Learn how to do this yourself. Its easy. Tip 2 - Every 10,000, remove pressure hose on DPF and inject DPF cleaner directly into DPF and then go for a highway drive for 30 mins - buy injectible DPF cleaner eg Pentrite P26 cleaner from Auto shop - follow instructions exactly on the can. Tip 3 - Add DPF Cleaner eg Penrite Enviro DPF Cleaner to a full tank of fuel every 5000Km Tip 4 - Buy a cheap OBD2 reader and down load a car scanner app eg Car Scanner Pro onto your phone to monitor DPF soot build up and Oil Dilution % - search Youtube to learn how this works Tip 5 - If you are not doing regular HWY driving - sell and buy a petrol / hybrid or EV car. I have a 2016 with 200,000 Km and gives me no trouble, I usually cycle through 2 sets of DPF flashing lights to get to 5000 km before I chance the oil - and I reset the trip computer ever time I change oil so I know when Trip A gets to 5000.
