Diesel Exhaust Fluid FYI
I saw an ad in American Hunter magazine and was curious...
Diesel exhaust fluid - Wikipedia, the free encyclopedia At first, I thought it was like muffler grease or a right handed hammer.

look for adblue, bluetec, etc.
pretty much every diesel powered vehicle in the current year lineup requires it.

Diesel makers seem to have settled on the SCR as the best means of cleaning exhaust emissions. Anyone who's dealt with diesel EGR systems recognizes the maintenance involved long term in keeping these systems effective. Additionally, meeting current diesel emissions standards with an EGR strategy is becoming more and more difficult.
However, there are already stories of high costs and unexpected maintenance needed for the converters and associated particulate filters. My opinion is that this technology as it applies to vehicles is still in development and many people will learn the hard way what is and is not acceptable in maintenance and operation. Now, as someone that appreciates a good bit of irony, I wish to point out that DEF is urea, a component of urine. However, the urea we buy in a bottle of DEF is synthetic because the process of removing urea from urine is much slower than manufacturing it. So, not only have engine manufacturers begun selling us urine for our cars, but they're arguing that our own urine is not good enough to use and they must make it for us. |

The question is would the system know or care if you just filled it with regular urine. We could be onto something here.

The system is able to test to be sure the correct fluid is in the tank. It needs to be a specific concentration.
Our Passat uses DEF / Adblue. One 5 gallon tank will go about 15,000 miles. Refilling it at the 10k oil changes makes it a non-issue. It works out much better than the non SCR / Adblue system the Jetta & Golf use, and is cheaper to run too! -J

Whats wrong with the system the Jetta uses? I'd been considering buying a Jetta...

It uses more fuel and runs the exhaust a bit hotter.
On an unrelated note the Jettas have also had problems with the high pressure fuel pumps and with condensing the post-cat EGR into water which pools in the bottom of the intercooler. Passats have an air to water intercooler, and don't have fuel pump problems They get better MPGs too, even thought they're a bigger car (as big inside as a LWB W126!!!) -J

Too bad VW doesn't see fit to sell us the Passat wagon anymore.

Hmmm, I'd thought the Passat wasn't available with a manual trans but on second look it would appear it is.
I'm surprised the Passat and Jetta don't use the same HPFP... I test drove a Jetta last spring and liked it, maybe I'll have to try a Passat now.

The Passat's engine is somewhat different. Different HPFP, intercooler, and injectors. Of course the exhaust / emissions system is quite different too.

I'm pretty sure the Jetta uses a particulate filter/regen system, not adblue.

The Jetta and Passat both have a DPF. The Passat uses SCR. The Jetta has a DeNOx cat and a H2S filter. That extra filter needing to be regenerated is why they use more fuel.
Here's the fuelly of our Passat: Passat TDI (VW Passat) | Fuelly Real world, we easily beat the EPA numbers. -J |
