I kind of have to agree with @Hoooper for most of this though. (Btw hooper, by DMV he means Delaware MAryland Virginia or DC MD VA). Our DMVs in MD are called MVAs because they want to be special...like snowflakes. JH, Have you tried reaching out to Clem as of yet?

Well if it gets hot enough (2k rpms) who knows. Beats dithering on the Internet while ones car is inoperable.

Although, that doesnt even address the question of whether or not our engines would even run with the everything disconnected after the EGR |

IMO..I have yet to see any photos of carbon buildup which would fall outside preventative. Hell, I'm at 49k moles so I may buy a bottle and try it out when I DIY my next oil change, DEF et al. |

I'd be quite cautious. Our US exhaust / emissions system is a work of art with complexity.
There are approximately 8 sensors devices in the exhaust tract of our 335d. Pre and post DPF temp sensors, O2 sensor, Pre and Post NOx sensors, SCR metering valve, SCR temp sensor, etc. Whatever soot / deposits you suddenly jar loose from the engine will now end up gumming up your expensive sensors. Coming from gasser cars, anytime a silicone product hits an O2 sensor it is shot. I remember way back guys were running different additives or flushes to their engine only to then accidentally kill all 4 O2 sensors. If it were as simple as running some cleaning agent through the engine, wouldn't BMW do that instead of pulling the head / intake? My cautious gut instinct is that they know an engine flush could prematurely foul the DPF and other emission components. (However I hope I am wrong as it would be an easier cheaper solution to avoid soot buildup) Just a heads up. |

Lubro Moly states this product is dpf safe. All good questions. Added: per MSDS it's 50-80% acetone and 20-30% 1-ethylpyrrolidin-2-one. Last edited by F32Fleet; 07-03-2013 at 08:52 AM.. |

Ok, I'll bite. I'll use the 109 and 244 on my next oil change and report back. I'm familiar with 109 from my diesel days and it was a great alternative to Sea Foam (which was eventually rebranded by Mazda and sold as "zoom power engine cleaner") when it came to maintaining compression and defeating carbon buildup in the rear rotor chamber. I'm willing to play guinea pig on that one.

Just noticing this comment... DMV is District of Columbia (DC) Maryland and Virginia, not Delaware.

Somebody told me a while back that Circle BMW in NJ would do this service, but I have never explored it further. They are located a bit south of Manhattan/Long Island.

Here is a rundown of the repairs for my D.
Replacing the Valve cover, intake manifold, and the turbo because of all the carbon built up in these components. Sending head to a machine shop to have them clean out all of the carbon. This whole process will take almost a month. |

Circle has done this for gasoline engines, not diesel. It just seems as the convoluted secondary intake path is hard to get at without removing the head. At least this is my assessment based on not a single example of walnut blasting a diesel with the head on the engine....
