Cool! Thanks for sharing about this.
Curious as to how involved removing the heat shield turned out to be?

You must get the exhaust out of the way. Not necessarily out, but out of the way. So if you unhooked all of the rubber hangers on the mid/rear of the car and dropped the exhaust you MAY be able to sneak it out. Other than that, just a few nuts/bolts and its off....

I will say this about AIS, specifically the kit I bought through an eBay seller- The quality of each piece is the best I've seen, but I've only seen Snow Performance' TDI kit and the AEM kit. The container is fantastic, but if bought alone I believe it is either $200 or $250, and that's just for a fancy 3 gallon sump container with some quality/peace of mind. The nozzles and so on- all nickel-plated brass- are top quality, but again, you pay for it if you piece it together. The kit was $499 shipped but would be $700+ pieced together. And my kit only uses boost, and even then it is on or off, not progressive. |

They are in pretty solid. The thinness of the tube had me worried but there doesn't seem to be any leaks - even when you consider i had to manhandle the thing back into place.

If you tap it a little bit undersize you shouldnt have any issue. Dont run the NPT tap all the way in, run it only 1/2 way or so and when you tighten the nozzle in it will seat really nicely in the threads. With the thinness of the tube, if you thread a tap all the way in you might end up making it too big since with NPT the further you tap the bigger the opening gets.

So have you unplugged the pump or other connectors for the tank? Curious as to whether you will let the OEM pump pressurize the fluid in the tank or eliminate the pump?

Pipe is tapped and both nozzles feel solid. Thanks for the tips everyone.
I have not touched anything else on the urea tanks/system. I would imagine unplugging anything I don't have to will set codes. However, what is this pressurizing of the tank you speak of? Please enlighten me a little more on how the system works, sounds like I wouldn't want anything pressurized..... |

Everytime I've removed the active tank fill plug after shutting off the car I get a "hissing" release of pressure. Not sure if you've noticed that or not? I'm not sure how much pressure is involved, and it may not be that big of a deal, but just wasn't sure if that would be a problem or not...

Now the active tank may be another story. Seeing that injector pump contraption attached to the top makes me glad I chose the passive tank. |

The hissing could indeed be vacuum instead of pressure. I didn't check that. Should be real simple to do, just have the cap off and turn the ignition on and feel for pressure/vacuum. Thinking about the venting description on the tanks ... what are your thoughts on the methanol fumes coming out of those vents?

Interesting info. Hmmm, methanol fumes...good question... Well, it seems those "filtered" vents would have some resistance to letting gasses out as compared to just having an open vent. Whatever hissing you are hearing is probably evidence of that. Plus I plan to run no more than 50/50 of meth to water and that is not flammable. That being said....I will let you all know if my car blows up! |

Here's some more pics of my methanol install. I needed to keep the pump fairly low for it to be below the pickup level on the urea tank so I placed it behind the rear tire near the OEM transfer pump. I pretty much kept everything connected on the pump contraption but just moved it out of the way. Made a bracket to mount the pump as you can see and was even able to jam an optional inlet filter in the stock bracket too. I think it might actually work.....

Really nice.
Looking forward to hearing more about how this works out for you.

Are there any reasonable kits that can be bought for the 335d with an easy install? I'm a novice at modding cars but really want to do this!

I have an update on my setup. I have my SCR tank plumbed and was finally able to test output. I am running the Devilsown pump and nozzles. I have a #7 and a #3 currently and with the 2 together I spray a volume of 26oz in a minute (over 3 cups). I am hoping you guys can let me know what volume these should be spraying according to those sizes but it certainly does not seem that the fitting on the SCR tank will inhibit flow at all.

I would also like to know how much time and how much work would be involved in installing/removing the kit every other year for smog inpsection.

This totally depends on how you set it up and how much thought goes into being ready to reverse. Mine I can reverse in no more than a half hour, I just unbolt the pump from the strut tower, remove the hose, put a connector into the washer line in order to remove the y connection to the pump, and then put a plug in the intake pipe. Very simple process. I can see it being much more complicated depending on how one chooses to install it though. |
