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.

I always thought looking at it that it would be easier to take out from the bottom.

Once we have software to delete it, mine is definitely coming out.

Was just out there looking at it again. I think you're right. Looks like I might need to break my engine hoist out of the back shed ...

Isn't Megaspeed the place that has a Toronto location? And then Ecotune has a representative in the states. Might be some others as well?

The guy who did SCR/EGR, DPF and DEF removal along with the software to go with it is named Jarek and he uses the 'Mega Speed' tune.

This is his business:

Link

This is an email reply that Jarek sent me earlier this year in February:

Quote:
1. Our software – chiptuning modification is prepared by Mega Speed in Germany – one of the best tuners for BMW and MB
Ø 50-55HP and 70-75TQ increase after modification , also better fuel economy
Ø Price $749 – ECU is tuning protected – we have to remove it and do bench programming

2.
Ø If You don’t need the DPF anymore and want to have the exhaust to be like original we are cutting out DPF, remove internal material and install stainless steel pipe inside – exhaust looks the same
Ø We don’t provide any of replacement straight pipe at the moment for E90 35D
Ø With DPF removed power increase comparing to normal tune 10% more
Ø The total price DPF software and hardware + tuning software is $1499 including EGR off if requested

Let me know if You have any questions,

Best Regards

Jarek

I don't speak German, but from time 2:30 to 3:00 they pull the DPF off this bmw. Doesn't look like they had to fuss with the engine mounts ...

That's interesting. I contacted Evolve again (been running their remap for a couple years now) to see if they had a way to remove the EGR, and possibly SCR/DEF and DPF. They responded that they hadn't done anything else with their North American remap. This response was last week.

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

I thought it looked just like ours in size/shape, but the connections/probe locations were different.

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

I emailed Mach V directly a few months ago. Their response was that they had not done a DPF delete yet with the tune but that they believed they could if someone requested that.

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:

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)
