Diesel Particulate Filters and Bio

Re: Diesel Particulate Filters and Bio

Ray is onto the right web site. the VW Watercooled website is a great place to research VW's.

I came across some really good research regarding the DPF's. Partically with Re-Gen and clean outs.
One of the Brisbane VW Members goes through the removal and refit after cleaning out the DPF.

From the readings in the forum I got the impression that a DPF has a life expectancy of about 140,000 KM's. Pretty dissapointing really if you pay 40 K for a car.
I'd expect the car to have a major cost in 3 years to replace the DPF. $4k to $6k.

I have had 2 Grand Vitaras both Diesel with DPF's. Not the fault of the first car but the second 2010 model was the real reason I got rid of it. My DPF failed in less than 3 months with 9k Km's and Suzuki wanted to deny warranty. Not enough highway miles ....... haha try and picture that conversation.
I must say that the 2008 model was a great car on B50 and ran really nicely. But that and a B Double didn't mix. The one real problem I have is the unknown, how long do you really have with these things ?

There will be a solution.

Re: Diesel Particulate Filters and Bio

the(albeit dodgy) solution is to remove it and weld some pipe straight through it then re-install the same way people have by-passed the excessive costs of catylitic converter replacements. Anybody know if this would work or would the dreaded computers go mental? Wouldnt work in the Uk though as they test emmissions every year for their rego checks.

Software fixes are becoming available for some vehicles to overcome the ECU problems following removal.
Re the pollution inspections - would the reduced emissions produced by Bio perhaps allow a pass? Would they visually check for the presence of a DPF. They are often very difficult to locate on small front drive vehicles.

Re: Diesel Particulate Filters and Bio

There is a fellow on another forum living in Canada who has bought a secondhand Jap import Landcruiser diesel. He ran it through a voluntary pollution check running B50 and it had a very high particulate readings compared to nearly all of the petrol powered cars and the newer diesel trucks that had DPF installed.
That makes me think that it is very unlikely that a car running biodiesel in any percentage with the DPF removed would be able to pass a serious pollution test.

- would the reduced emissions produced by Bio perhaps allow a pass?

Re: Diesel Particulate Filters and Bio

Being second hand what contribution would older injectors make to the particulates? I think clean injectors might go a long way to stopping this. Better combustion?

Re: Diesel Particulate Filters and Bio

That certainly could be the case.
On the other hand it might be like when petrol engines went to catalytic converters. Catalytic converters were so good that the manufacturers could loosen up on the other things they were doing to reduce pollution.
It is possible that removing the DPF from a car specifically designed for the use of it will result in more pollution than cars made a bit earlier that were not designed with a DPF in their pollution system.

It would be very interesting if someone had web site that discusses this.

I have a friend who I taught to make bio, He now has the latest model. He removed ofending item ,washed it with high pressure hose and put back in place with no trouble. It is a common fail motor and all good. Cheers Grey Hair. PS think it's a V W never paid much notice as all the shiny small cars leave me disinterested. 2006 105 Cruiser with pusher pump and twin throw away filters.

I bought a 307 HDI and a DPF With a few issues, got it running and roadworthy, rego etc. I filled it up with bio and it was running great until my wife drove it and it stopped dead. The scanner says crank angle sensor, so I've ordered a new one. My plan is to delete the DPF and EGR systems, HDI tunning in the UK will remap the ECU. I really didn't need car issues over the holiday period. Ill report back when I get it running again.

I got it running again some weeks ago, it threw up a DPF not detected error code which lit up the engine check light, After a bit of fluffing around, HDI tuning sent me the wrong ECU map, but they were very good about supplying the right map for deleting the EGR and DPF. I pulled off the DPF and found that someone had been there before and drill a hole through the middle of it. I remove the rest of it, the temp sensor and pressure sensor were disconnected and the EGR was blocked off. I remapped the ECU and the car now runs just great on bio.
So not that hard to delete the DPF and remap the ECU so it doesn't throw up an error and the engine runs great and a bit quieter on Bio. Also, i can now run normal engine oil, DPF engines require special oil that is more expensive

I have a 2006 Peugeot 307 with the 2.0 litre HDI engine and the owners manual says it is able to tolerate B30. I carry a 10 litre container of B100 and add it to a one third tank of fuel and it has not caused grief yet - over a year. These engines have a chemical that is dosed into the fuel tank every time the fuel cap is removed and replaced and this assists the DPF to burn off correctly.

We have a 2009 308 with the same engine. We ran with B20 for a while too until getting BioD became too difficult. Note the owners manual requires the fuel filter to be changed twice as often when using up to B30. We also found the fuel filter blocked up a couple of times too which reinforces the requirement to change the fuel filter more often

My 307 is still running great, gave it an oil change and put in the non DPF oil which made the engine noticeably quieter, It was always a bit rattly compared to the 406.

When using Biodiesel or Used cooking oil for the first time in a diesel engine, you will find that the fuel filter will block after a short time (within the first 2-3 tanks of fuel) as it kills off the diesel bug that lives in the diesel fuel tanks. You may need 2 or 3 filter changes to get rid of the dead diesel bug from the fuel system. You fuel filter changes may not need doing again for years, once the dead "bug" has been removed by the fuel filter in the first few tanks of Biodiesel / Biodiesel blend / WVO / WVO blend.
This has been my experience over the last 24 years of making & using Biodiesel / using WVO. or and blends.

This is a good update. Can you give a link to the crowd who modded the ECU and how that worked for you. Ie, you had to remove the ECU and post it to them?

I’m remaining running my Peugeot 307 with the 2.0 Hdi on a bio blend of less than the B30 blend Peugeot says it will tolerate. I might push it to B50 and see how it goes retaining the DPF. The EGR is blocked with an 8mm hole in the centre and this has slowed the soot buildup in the intake.

I used HDI tunning in the UK you will need a KESS programer, which plugs into OBD port, to read and write the ECU, very easy to use, just read the ECU send them the file and they will send you back the New file with the DPF and EGR and a remap. I have not had any problem with engine check lights, and I run 100%bio.
