Reliability is good but driveability is down. Stock tune is vastly more driveable. Lost all low end and midrange torque substantially down. Do not do ABC deletes unless you have no other choices. If the DPF's were $500 like they are in Europe, I would have just kept everything intact. Sadly, a DPF in North America is $2,600 just for the part and about $1200 to install.

Something is wrong with your car.

People are practically giving DPFs away on the FB group. Search for North American BMW Owners Group. Torq3e is the moderator there. I agree with the poster after you. You need to get it sorted out by a pro. My driving experience is super easy if you keep your foot out of it. And if you don't, it is a blast.

I'd love to, but all the BMW diesel pros are east of the Mississippi river, way over there. I've replaced all vacuum stuff except the actuators, which don't leak and operate fine. I think the tune is just disappointing. Not willing to spend another $1000 on a tune in the hope that it is better. Tired of guess & check crap. No one knows how to properly diagnose performance issues on these cars unless codes are thrown. I have none; just a slow car.

I guess it's just a diesel. I'm not entirely unhappy with it. I tow loads with it, and it does that well. Economy is 29-31 mpg, about normal. I can make it scoot a little if I really get on it (It's a quick-ish car, not a fast car). But it won't win any races.

Used, sooted up DPF's don't do any good though. I did it as a short term fix, and it *kinda* worked not well. It's an option, just not a very good one for the high labor costs.

Can't we just admit BMW made some serious design flaws with these cars?

If 30 or 40 thousand mile units aren’t worth your time, okay.

I can’t say I have any issues with low end response on my 335d. I still have my dpf intact and I have ridden in cars with dpf/scr delete. The deleted cars seem just as responsive if not more than my D.

The dpfs should last 150k-170k. I’ve test driven used x5s with the m57 in that milage range with original functional dpf.

These cars emissions problems were not generally the dpf, they were too much egr causing early carbon build up, scr tank failures, and scr catalysts getting too much crystal build up. The dpfs were deleted mostly for performance along with everything else.

[Blown284]

Wish I did the deletes a lot longer ago. Gas mileage went up, power went up, the smell leaves a bit to be desired if sitting at a redlight and the wind is blowing in your direction but that's something I can live with.

I think a lot of people also deleted dpf because they got a dpf light and needed to pull it to get cleaned. More cost effective to delete it than clean it to only have it clog later down the road.

But I guess a lot of dpf clogging had to do with other factors that wouldn't allow the dpf to regen properly

[Spyro235]

I'm deleted for 3.5 months, and 12k miles. Yes.... I drive a lot. I'd had 0 codes thrown except fir the glow plug module needing replacing, but that's a known thing. I drive the thing pretty hard, it gets a lot of highway miles but it's done around 1500 miles of towing 5500+ lbs in that time. Lifetime average over 6 months/ 19k miles is 26.6mpg, but that includes all the towing which really brings it down. Real average would be around 28, as I get 27.5 even when some of my trips are into nyc in city traffic. after deletes, I've literally only put diesel in it, changed the oil, and swapped to my summer set of wheels. Heck, 2 days ago I did some light off roading with it, on a muddy woods trail up to my buddy's old farmland.

Dude there is an awesome shop there in Phoenix that did my 335d. They are great. Its called parts score. 7707 E Acoma Dr #113, Scottsdale, AZ 85260. I was having all kinds of issues with my 35d and they fixed all of them. DPF, SCR, EGR, swirl flap delete. Malone stage 2 tune. and more. I took my car to the drag strip before I did my transmission tune with XHP. I smoked a 2016 dodge charger even though I messed up my launch(First time at the track and still didnt know how to brake boost)

Yeah this isn't correct. This may be true with a N/A car in some cases but these cars are turbo charged. Without the corks the turbos can spool faster thus creating power quicker. I hope you got a quality tune.

I just purchased a 2010 335D from my pops back in Detroit MI. This is what he had done at 75k miles...

-ABC Delete
-SCR Delete
-EGR Delete
-Swirl Flaps Delete
-Harmonic Balancer replacement at 120kmiles
-Race downpipe w/race Cat
-Stage 2.5 JR Tune
-Trans tune for sport and regular modes

He passed the car on to me with 164k miles on her while the car showed a code 4350 that had been causing him heartache for months. I was able to fix the 4350 by tracing it back to a melted vacuum line between the vac res. and the main plenum. $.25 cent splice and I am back up full power.

Intakes were walnut blasted at 75k and show almost ZERO CBU after the last 80k+ miles.. Since the ABC delete the only issue was replacing the harmonic balancer (which literally fell off the car when he parked at his work one day....), and this more recent vacuum line issue that was causing the 4350.

Car does smell like diesel when the engine is cold, not an issue once it is up to temp. I drive with the front windows down and the sunroof open all the time. I guess it just depends on how much you care about the smell...

No emissions testing on my side of the mountains, and I am going to see just how long I can make this car last!!

Do you mean 4530 or is 4350 correct? 4530 Just popped up for me and we're thinking vacuum lines are a good place to start...

It was 4530, thank you for the correction. If you have a small handheld vacuum pump and some line caps you can test most of the vac system with just the engine cover removed. Hopefully you find your culprit as easy as I did.

Hey All,

New to the forum and this is a not so new thread, but I am curious if anyone knows of any proper performance and Tuning shops in or near Portland OR that can help me with my 2010 335d emission delete and Tune. Thanks much!!

[COLD_WRENCH]

How’s the 335d now? I am trying to figure out what Tune and downpipe to get

I'd go with the VRSF down pipe, at 270 it's a great deal and lots of positive feedback, wish I went that route instead. I heard great things about BRR but he seems elusive. Got a hold of him through text, all was good till I told him what state I lived in then...crickets, lol. Went with AAR instead with the 2.5, great experience/customer service with Andrew. Not super impressed performance wise for 1k, but at least it'll save me emissions headaches and money in excess of 1k down the road...

I have literally seen smoke after my deletes maybe twice and they were small puffs. And as far as smell I only notice the smell if I'm standing behind the exhaust while the engine is running.

[lnxguy]

All deleted cars will puff a bit of smoke on startup or when WOT. Even more when it's cold. Comes with the territory.

Follow-up on anybody in the Portland area able to do an emissions delete?

[lnxguy]

You're asking this on a public forum? LOL Not today EPA.
