DIY DPF access/removal/replacement questions
So, as I was putting my car back to stock for its yearly service, I found myself looking at that big DPF canister on the exhaust. Started thinking about what it would take to get in there and remove it, hypothetically of course, for if/when it gets replaced/removed...
Has anyone personally removed the DPF? Curious as to what process/technique/tools were required to get it out. It doesn't look like too a bad of a job from the few minutes I spent looking around down there. The closest thing I could find on a quick web search this morning was from here: http://www.bmwland.co.uk/forums/view...p?f=4&t=148328 I took the car, like I did with the E61, to a friends garage and used his 2 post ramp. Easiest way we found was to support the engine and remove the engine mount. With that out of the way, and now with some up / down movement of the engine, with the right tools we could remove the engine mount bracket. With that out of the way, the DPF just falls out no problems. Although, we have our steering wheel/shaft on the other side, so I'm wondering if it might be an easier job? |

This is a good question to post. From reading that thread the guy supported the engine, then took out the bottom engine mount and unhooked the dpf canister from the exhaust and it dropped out. This is probably going to be a job I'll do at some point if i decide to keep the car and bypass the dpf.

Wonder if it would be possible to take the DPF up and out since we don't have the steering wheel/shaft in the way? Removing the air filter assembly, the front plastic firewall/tray stuff, the strut bar ... just a thought I didn't get a chance to pursue.

If you have more info on this please let us know. Perhaps Mach V is developing their own tune? |

Seems like a lot of the youtube videos show europeans removing the dpf's, cutting them open and removing the DPF section (but leaving the Diesel Oxidative Catalyst in place if its a dual DOC/DPF like we have) and then welding it back up. This way it can still pass the visual inspections. Also, the DOC still helps a bunch with emissions reduction, particulate reduction, and with a lot of the smell. From the little I've been able to gather, removing the DOC doesn't seem to buy much advantage in terms of performance/longevity. But I'm not claiming to be an expert on this ... |

I contacted a few weeks ago Jr electronics aka Jarek and the secretary told me that they werent doing DPF pipes. I might go the route of gutting the DPF or even installing the tube inside the DPF whatever can be down to IMPROVE my car

Been doing a little reading on particulate emissions. Kind of eye opening to me to see the extremely small impact strapping DPF's to highly efficient light duty diesel engines have on the total particulate emission problems. Things like tire dust, brake dust, road wear dust, etc are HUGE contributors.
For example: http://www.unece.org/fileadmin/DAM/t...RPE-65-20e.pdf After thorough research of the air at highway with moderate traffic, the researchers found between 3,800 and 6,900 tyre particles per cubic meter of air while more the 58% of them are under 10 microns in size and therefore are able to penetrate into human lungs causing bronchial asthma, allergic reactions, as a result of skin and mucosa contact–rhinitis,conjunctivitis and urticaria. According to the research carried out in Moscow [2] the core pollutant of the city air (up to 60% of hazardous matter) is the rubber of automobile tyre used up in a small dust. As shown in the above analysis, tyre dust emissions due to tyre protector wear (in g/km) significantly (by 6 - 7 times) exceeds emissions of particulate matters with exhaust gases of passenger car engines. And then another interesting read: http://ec.europa.eu/transport/roadsa...culates_d8.pdf |

I saw Jarek in person this summer. Let's just say he has "guys" who can do it. I get the impression Jarek is trying to cover his ass just in case.

I would cover mine, too, with the fines for Edge and others allowing removal of DPFs and other equipment.

I have decided I will GUT OUT the DPF as another blogger has done and have my friend from Poland do the DPF and other issues remove from my ECU, I plan to move to Costa Rica eventually lets say next 8 yrs and I dont plan to move to the states (already lived there fore 25 yrs)
