TDI on Motor Age magazine

[oilhammer]

Our diesels made the cover story of the new Motor Age magazine! nice little VAG diesel article inside.

In Vol 130, No 9.

Very cool. Thanks oilhammer!

CoolAirVW beat you to the punch. His post also includes a link to a decent webinar.

wow. pretty good article. I was waiting for the bashing the whole time, but apparently he took a neutral approach like he should have. Making us diesel mechanics proud!

Nice read. Thanks

Excellent reading with plenty of 'new information' for those of us who don't yet own a CR TDI. As an example:

"A huge step forward was achieved [on the CR TDI] with the use of pressure-sensing glow plugs (PSGs) for closed-loop combustion control. Using a piezo-resistive element and an application-specific integrated circuit (ASIC) built into the glow plug body, combustion pressures in the cylinder can be measured in real time. This information then can be used to adjust injection timing, thus enabling compensation for varying cetane ratings in diesel fuel. Because combustion pressure is directly related to temperatures in the cylinder, the PSG feedback loop can be used to adjust fuel delivery to limit peak combustion pressures and thus, NOx formation. Misfire detection also is much more accurate using a PSG."
​

Article also includes a high-level overview of DPF, high pressure EGR and NOx catalyst.

Yes, I was actually impressed, as usually those articles have a lot of mistakes, misinformation, or silly one-sided commentary. Nice to see one that was factual and straightforward, as well as informative.

Nice for me to learn about the differences in all these engine names and numbers that get thrown around. Lots of information for the non-machanic.

- "The number of shops that perform TDI service are relatively few and far between, and the good ones are rarer still."

So true! And you, OH, are by all accounts responsible for the existence of one of those rarer still shops. Tucson is a bit of a dead zone. Good article. A lot has changed since my ALH.

Pressure-sensing glow plugs (PSGs).... that sounds like a 500$ glow plug problem...Are they bosch because i'm not buying it lol

 

[glitdi]

Nice find nice read... thanks!

They are Bosch, and they are $167 apiece. Technology does not come cheap.

 

[MyAvocation]

Ouch! That was my first thought after reading of PSGs. Gone are the days of $5 Buru GPs for the ALH.

Pressure-sensing glow plugs (PSGs)....

Internal name: CSGs (cash-sensing glowplugs).

^^ x2. Thanks, OH. I found this article to be well researched, organized and presented. It serves as an excellent chronology of the VW TDI engines. Nice to see someone with mechanical aptitude who can write well. Errr, I mean.... nice to see someone who can write well, and also has mechanical aptitude

 

[kjclow]

How about... It's great to see someone with mechanical knowledge that can express it in such a way that we can all understand it.

Holy ****. My $16,000 2.5 Jetta is looking like an economy car.
