No joke.... exhaust fluid.

We got a box of special tools delivered today, I was seeing what kind of crap they sent us now and came across something that looked like a big version of the DSG transmission fluid filler tool, but it had a weird a label on the side on the container portion of the tool.......








I thought it was hilarious so I started looking into. And came across some interesting stuff. It's for the V6 turbo diesel Toureg that's coming out later this year.

The last diesel Toureg was pretty impressive for a luxury SUV, the V10 Twin Turbo engine was a monster (If you haven't seen this it's pretty impressive IMO http://www.youtube.com/watch?v=05zRyoBbcfI ) but the roughly 80K price tag was a big turn off . Well after new regulations the diesel VW's were gone for a few years and the new TDI has been pretty highly anticipated. So finally for 09 diesel Toureg is coming back....

Here's some of the interesting info I found out about it, the exhaust fluid is injected into one of the catalytic converters, its injected constantly when its running, it reduces NOX emissions by 90% and turns it into water and nitrogen. There is a tank mounted under the spare tire that's holds about 4 gallons, the fluid will last for 10,850 miles and has to be filled by VW service department. No part number for the fluid yet so I don't know the cost of it. It's 222 hp and 405 ft.lbs at 1750 rpm. It's rated for 17/25 mpg. It's a clean diesel, supposedly you can hold a white rag over the exhaust while its running and it will remain white, no crap coming out the exhaust.

It's the cleanest and most fuel efficient Toureg yet, 400+ tq, should be about the 40K mark.... doesn't seem to bad other then having to come in every 10K to pay us to fill your exhaust fluid LOL, but it gets worse....

They decided they were gonna limit the production for 7XX of them, enough so every dealer gets 1 to sell, and on top of that you don't get any options, it comes in 1 color with 2 different interior options available, you can't pick and choose different options they are all the same. I don't know if they have sunroofs, heated seats, heated steering wheel, power seats, 4 zone climate control etc.. but if they don't your SOL, you get what you get. @!#$ idiots. VW = fail. Huge fail.... like Z Yaaaaaa trying to figure out the difference in coating and absorbing type fail. They had a decent thing going but they dropped the ball again.

sounds like a great starting idea and yeah.....nice job vw....again

Nice. I really enjoyed the 10,850 on the dot. We just can't do 10,000 miles? Haha I see more of what you deal with day-to-day .

LOL @ second to last sentence!

Hurray for urea (sp) injection. They couldnt use a DPF?

The fluid is urea isn't it? Same is Mercedes, and probably anyone else who is going to sell diesel engine in a passanger vehicle in North America will have to use.

Looks like it is about $7.50 a gallon for the Mercedes fluid.

The 50 state-legal 2009 Jetta TDI and Honda's new diesel does not use urea injection. VW Jetta is one of first "clean diesel" in the US. But in order to achieve the low emission, they need to run on ultra-low-sulfur diesel.
Mercedes' E-class Bluetec doesn't need it either, but the same engine in the SUV (ML-GL) line does use urea.

it has urea in it, I'm not sure if that's all it is.

Every "passenger" diesel engine produced after Jan 1 2007 is required to run on the Ultra low sulfur diesel.

^Fact.

I would check again Darkstars on the 2009 Jetta TDI, as I'm 99.99% sure that they don't use Adblue or urea. What the Jetta uses instead is a NOx-storage catalyst, which is basically a reservoir that temporarily holds the noxious emissions, like a particulate filter, until they can be burned off during one of the engine cycles. Jetta TDI meets the most stringent Tier 2 – Bin 5 emissions standard. The 2.0 liter can operate on B5 biodiesel without complaint

On the Mercedes if you run low or don't have urea in in the tank, you will only have 20 more starts until you go and replenish it.

I never said it was on the Jetta, the Jetta is just a common rail clean diesel.... this whole thread (and exhaust fluid) is about the Touareg

absolutely hilarious. i lol'd and i never actually do that.

as for the original subject, it sounds interesting. im curious what 4 gallons plus service at a stealership is going to run though

If people in the US will be willing to use a system like this maybe we will see a few more diesel cars on the road. DPF systems take up a lot of space and from what I have been able to find, urea is just as efficient.

What displacement is the engine?

urea reduces NOx. DPFs capture particulates (the black smog that comes out of tailpipes). completely different.check out the new silverados with dpfs and scrs (the thing that takes the urea). btw, they get urea from pig urine.

Urea can also be used to control soot. Ulness of course GM was lying to me when I went through their training before the LMM Duramax came out. Really no need to check out the newer Silverados with the DPF as I saw them before they came out.

The exhaust setups are getting pretty ridiculous. The common rail Jettas for example, exhaust comes out the head, into the turbo then into an oxidation cat, then into a diesel particulate filter (DPF for those who aren't catching the acronyms) then into a low pressure EGR filter, then a NOx storage cat, then through the exhaust throttle body, then to the H2S cat, then to the muffler and out the tailpipe and the whole system has about 9 sensors in it, exhaust temp sensors, exhaust pressure sensors, flow sensors..... that's one hell of an exhaust LOL.

Which engine?

The Jetta has a 2.0 turbo
Touareg has a 3.0 V6 twin turbo, another kinda cool addition for that thing, both of it's turbos have their own intercooler, the intercoolers are completely bypassed when its cold to help the engine warm up faster.

I though the GM trucks were bad with an oxidation cat and a DPF. Does VW even need to run a muffler on those cars?

What size is the engine in the new Toureg?

I'd probably not necessary to have a muffler (there's even what appears to be a resonator in there somewhere). But it works that's for sure, If you know it's a diesel you could pick up subtle hints that it is but if you just walked up to it running you wouldn't know it was a TDI, its doesn't smell or smoke and its QUIET. They did a pretty good job insulating engine noise on it.

There is one VW I would honestly consider buying and its the Jetta Sportwagen TDI (but seeing as I drive 4 miles each way to work there's no reason for me to go diesel, let alone any new car right now)

urea doesn't control soot. it's only for nox. i should know, i work in teh emissions labs

The page was loading slow because your post about the displacement did not show up before I started typing my post. Not bad for a 3 litre.

rofl?
