Frustrated, I did a few more runs last night at the expense of my new tires and sleep but at least now I have "stock" results, my best time I had to let up before 1/4 but shows in the 1/8

My options are using a hacked solution with low flow rate just to keep the CBU at bay and slowly clean it. Next year or the year after I can look into a proper solution. |

That is precisely what I am doing now,(mostly for cleaning at this point) my system is a cooling mist pump with a deviles own 1 stage controller. I plan to upgrade to a stage 3 controller at some point. I have now put in about 2xxx mi since installing it, and plan to eliminate egr altogether soon, at which point I will take more pics so everyone can see the difference. BLOCK EGR FIRST, this is where all the junk is coming from. It's cheap and easy, then meth, tune, and then.... A beast of a car with great gas milage, and durability

Gonna start this thread back up....Drained my urea tanks tonight and meth kit is on the way. I really want to use one for meth and run the pump in the trunk. The stock lines from the urea tank to behind the driver's rear wheel are about 1/8" ID. You guys think that's large enough? Not sure what size the kit includes as mine isn't here yet.
Also, Tdi if you are here, I l know you posted a pic of your pump in the trunk but I can't find it.... |

Using the urea tank for meth along with full tune and emissions items removed is sort of my dream. Sort of. |

I'll be interested to see your progress on this. I was going to go that route as well, but have been really pleased with this setup and like having the warning LED for when the tank gets to the ~1/3 full point.

Now about the tanks. Does the following sound right? "The top tank is the passive tank and holds 4.5 gallons and the lower one is called the active tank and holds 1.6 gallons" Found this posted by Greekboy on a youtube video. I would rather use the larger top tank but my concern is if the factory line running to the pickup (1/8" ID, MAYBE 3/16") is too small I may not have access to where it hooks to the tank. My other concern is if the line is that small, chances are the elbow at the pickup is the same ID or even smaller. Any input here? Guess I might have to do flow tests with a complete kit to see if it will inhibit flow.... |

Combox or TCU/MULF would be in that spot. Also if you are using the urea tanks, there *might* be a lift issue with the pump mounted above the tank. I know the install guides say to mount it below, but have not tried mounting it above myself.
If using the urea tank, I would just tap a new location for the 1/4" fitting at the lowest point. You can even put a level sensor in like I did so you know when it's low.

I found the other fitting on the large tank, had to take the big heatshield off and its right there. I also noticed that the fittings on both urea tanks are quite a bit larger than the hose used so they may be big enough. Regarding level sensors, I know the car keeps track of the urea levels to some extent so I wonder if we can find something that will read that signal at the computer. Maybe I can whine to the BMWhat guys to add it to their app. That'd be a sweet setup. |

I mounted my pump behind the wheel arch where the DEF fill area is located, tank is right above it inside the trunk. My line is ran outside the car and pretty much follows the brake lines within the belly pan. I have pictures if you are interested in going that route.

Tdi question can you use the OEM line and place a new line to route it to where its supposed to be connected can it be possible? this thread is very interesting and i was thinking of doing it that way now that you put the schematic about it

If ever necessary, it's a lot easier to plug a hole in the tank than replace the factory lines. Probably much cheaper too.

A couple pictures from my install. I didn't take any of where it's routed under the car, but at some point when i'm back under there I will.
Line to the pump & wires entering the trunk. You can see the 3 washers for where the pump is mounted underneath. Pump mounted. I trimmed the plastic bracket where the purge/fill lines are mounted with some dikes. It doesn't disrupt the function at all and allowed me to get the pump further away from the heat shield. Red line shown is the one which feeds from the tank. View looking toward the rear of the car. I followed wires/hoses until the line was over the rear suspension. At that point I followed the brake lines all the way to the engine bay. Many 8mm and T15 screws to get the belly pans off. Where it finally comes into the bay I only have 4 wires running inside the car from the dash area to the rear.
Picture of the level sensor mounted in the tank. If I could do it again i would probably mount the sensor a bit lower. For a 2.5G tank it closes the circuit at 1G remaining. The sensor was about $6 on amazon.

Stevers I like that set-up. Guaranteed to cause puddles on your passenger seat and get you laid.
