dev9bov9 Posted March 29, 2015 Posted March 29, 2015 need cost effective solution for dpf problem cars going into limp mode tried running up motorway in 4th at 4000 revs to clear helped a little . can u recommend a good company I can send to be cleaned must have quick turnaround ? or can I take itr off and jet wash it ? any sound advise would be helpful thanks simon Quote
Johndouglas Posted March 29, 2015 Posted March 29, 2015 Yes - several guys on the forum have taken them off and cleaned them with a jet wash. I believe it also helps to give them a soak with an alkaline solution first. Quote
dev9bov9 Posted March 29, 2015 Author Posted March 29, 2015 thanks that sounds like good advice I ran it up motorway on 4000rpm which gfot it out of limp mode thanks for reply Quote
paul.h Posted March 29, 2015 Posted March 29, 2015 The adverts I have seen for companies that will clean them are not much different to the cost of a new one. Some appear to do a chemical clean and others use a high temperature oven to burn off the ash. So the jet wash appears to be a good first option. Quote
dev9bov9 Posted March 30, 2015 Author Posted March 30, 2015 I have had quotes for £420 which is a total rip off . I run the car up the motorway in 4th gear at 3500revs for 20 mins which must of burnt off some of the soot ,the car is no longer in limp mode ,the warn ing still sounds which I guess needs plugging into a computer" another rip off"" to be reset . I herd oven cleaner is good soaked over night then jet washed , is it illegal to tamper with dpf ? would I be breaking the law by cleaning it ? Quote
Johndouglas Posted March 30, 2015 Posted March 30, 2015 I'm pretty sure there's no law against cleaning your particle filter - other than not allowing the foul water to contaminate the drains. Yes, I've also heard of oven cleaner being used. Quote
paul.h Posted March 30, 2015 Posted March 30, 2015 In the Haynes manual for the Peugeot 406 covering the 2.2 hdi I seem to remember it saying to clean the dpf. If it is the engine management light that is coming on or just a warning message, then these should probably clear once the fault has gone but you may need to switch the ignition on/off/run the car a few times. If it is a warning the eolys fluid level is low then clearing that is not so easy once the fluid has been topped up. A Lexia diagnostic will be needed to tell the car the level has been topped up but on early cars it may need the eolys ecu replacing - however, people on the forum have said that provided there is eolys fluid in its tank then it will continue to be added despite getting the messages. This is since the eolys level is not measured but is calculated on the number of fuel tank fills triggered by the magnets in the filler cap actioning a switch when it is removed/refitted. On the drains - you should not put anything down ones that go to rivers or other water courses apart from water - this will include road drains. Drains from your house that go to the sewage works for treatment are ok for normal household water soluble things but not things like oils which should go to your council recycling centre. Any solids should be ok to go in your waste bin for landfill unless classed as special waste. Quote
dev9bov9 Posted March 31, 2015 Author Posted March 31, 2015 thanks guys! took all your comments on board ,saved potentially hundreds of pounds .all my warnings have gone ,cost me £15 to plug in to computer and as you quite rightly pointed out SWITCHED THEM OFF! they where zeroed as the chap putt it ,I am responsible , and always dispose of my rubbish responsibly regards devinebovine Quote
