DPF Cleaning
2011 GL350 BT with 135k miles. Clogged DPF likely due to other issues. Quote from both Indy and Dealer is $4k +.
Has anyone had experience at removing the DPF and having it "baked" and cleaned?
If yes, any recommendations and vendors? We're in Southern California, but have read on this and other boards that folks have shipped their DPFs for service in other states.
Thanks.

GL350 Bluetec and GLS580
Try Sprinter forums or just google your local area for those services.

I have DPF regeneration shop in Vegas area - actually in Boulder City but they could not restore my DPF.
They used ultrasonic cleaning and it did remove black residue from the ends I can see, but even I put it on, the car will not rev past 1800 rpm.
Now for my 250 Bluetec I order new DPF in June. Last feedback from the dealer is that rebuild DPF will leave Germany on August 8.
My car is a brick in garage for 2 months and counting.
Good luck.

Had DPF replaced once along with two NOx sensors under warranty, on my OM642 Sprinter before engine failed around 140k miles (stupid but expensive mistake). Had I another OM642 powered vehicle it would get the same treatment as my now 214k mile OM648 and EVERYTHING emissions related would be deleted. Perhaps it’s easier for me to rationalize living in a non emissions controlled area but, which is really more eco friendly, the 38mpg I got on the drive home or the 27mpg (both real, calculated values) the car got stock. In California I get it, you’re pretty much screwed if it won’t pass CARB testing, perhaps list it for sale in another area, across state lines? A $600 reflash can undo that whole situation with the help of a friendly exhaust shop.

Does the emissions delete really make a difference in fuel consumption? if so, then I can also expect more oomph when accelerating, right?

I just had mine done last night. I'm in central Florida. I used a place called Williams diesel, was an ad on internet. I called and talked to them first, said I should drive over, 1.5hr drive, and let them diagnose then if determined if overnight baking would be needed. The cost of the baking was $450. So I thought the diagnosis would be I applied to the cost if they did the cleaning, if needed. So, I drove over, they immediately took my r350 in and checked it while I went to a restaurant for brunch and killed about 2-3 hrs. They finished, and said if I left it with them, and they removed it, cleaned it, and reinstalled it would be $1100+ dollars. I told them I would get back to them and then it was mentioned about how they offered the drop-off service for $450, so I told them I would bring the DPF back the next day (yesterday). I picked it up at lunchtime today and drove back to my Indy who still had my car on lift and we installed it together. It took about 30 min to reinstall. It's pretty easy if you have a lift, but I wouldn't do it without one. So I would recommend to negotiate with a local independent shop to remove it, and send it yourself, then have shop reinstall. It will of course need to stay there for a couple days. My Indy wasn't even going to charge me, but I forced a hour of labor on him. It's the right thing to do. Now the diesel shop didn't apply my diagnostic fee of $130 to the $450, which did pissed me off. If that had been clear in the initial phone call, I would have just pulled it and dropped it off. It seems to be a little zippier, but we didn't readapt the ecu to the cleaned dpf, because it was at the end of the day, and I thought we could do it Monday. On the way home the same DTC for regen frequency came on, and I quickly cleared it, and it hasn't come on since, but it has only 10 miles. I know that's no help, but we'll see over the weekend and readapt Monday. Now I'm not absolutely certain a readaptation is required, but regardless. It couldn't hurt, and my Indy with the star won't charge me, since it only takes a couple minutes to do. Since, I know it's a cleaned DPF, I don't care about the DTC code over the weekend and if it shows up we'll address it Monday. Btw, I had already tried new differential sensors, since they were cheap and easy to get to, mine were behind the passenger air filter box. And since I pulled the dpf out with the steel tubes to the diff sensor still attached I blew them out to ensure the weren't broken, crimped, or clogged. I'm sure there's a local DPF cleaner within a few hours of you. Hope that helps.

I can't wait to yank that SOB outta there and be done with it. Malone Tuning has gotten back to me with great news; There's a local shop literally 20 minutes away who can do the DPF/DEF/EGR delete for me.

Shifting timing of injection events to compensate for no EGR and such by as little as 1-2 degrees to get peak BMEP in cylinders at 12-15 degrees ATDC allows even higher efficiency and even less heat lost to motor increasing the BSFC or thermal efficiency of the motor and fuel.
Overly technical probably but yes, ridding our motors of this BS is good for power and economy and longer engine life.

I removed my complete exhaust with the DPF in my garage (pipes were fused and couldn't separate the DPF) with the car (all 4 wheels) on ramps. I took the whole exhaust assembly to a shop here in the Toronto area and the guy was able to cut out the DPF from the rest of the exhaust assembly, bake it to turn any residual soot into ash, remove all the ash and weld it back up. I reinstalled it on the car, changed the differential pressure sensor (DPS) and it's working fine. The ash code I was getting is gone. I also had the catalytic converter and NOx filter cleaned out. As long as there is no damage to the internals in the filters ie melted elements (honeycomb, catalyst,etc) it should be serviceable. The tech should be able to check that to make sure before cleaning otherwise a new component (or a delete) would be required. In most cases the individual components can be serviced and re-used.
