Lol. It's interesting, the guy who sold us the car said it was a timing chain. I didn't believe him because my tuner said they were belt as well.

Don't get me wrong, I love my ALH a lot. This new passat is definitely neat. But it'll be my wife's primary car. I want to make sure it's reliable and well taken care of.

The Passat didnt have nearly as many failures of the HPFP as the Golf/Jetta did. And all of the ones that I know of (only 3 that I personally know of) they were all confirmed failures due to gasoline contamination.

So I do not believe the HPFP is an issue on the Passat.

The Turbo failures were more prevalent on the 2012 and very early 2013's. The later 2013 - 2015's werent nearly as problematic.

The 2012 - 2014 has an adblue heater that is separately replaceable and is kind of a known failure point. We hope that is solved with the newest revision of the pump, but time will tell.

the 2015 Passat adblue heater is built into the tank and is not separately replaceable. They havent been as failure prone, but again, time will tell.

Either way, the adblue system is covered under the Dieselgate emissions warranty.

And since you brought up the Dieselgate emissions warranty just now, the 2015 has a better warranty. 11 years or 162k miles for everything fuel, adblue, engine, or turbo related. The 2012 - 2014 is covered for 10 years or 120k miles.

Lastly, the 2015 Passat gets the 150hp CVCA engine while the 2012 - 2014 Passat gets the 136hp CKRA engine.

But all this is moot since you brought the 2014 home. LOL.

Its still a good car, but it will get sh*t mileage with those 5 mile drives every day. When I was making that commute, I was getting about 28mpg average on the tank.

See that there, that's the info I was looking for, I really appreciate your input. Only reason we went with the '14 is because the price was just right. Now I can rest easier knowing I don't have to worry about the turbo and pump as much.

Now to teach my wife not to idle the car a bunch... And make sure our lovely Oregon gas attendents use the green nozzle.

Actually, if I am not mistaken, you can pump your own diesel.

It doesn’t have the same law attached to it thanks to truck drivers.

Of course, you may get some push back, but just tell them “Piss off, it’s a diesel. I can pump my own.”

Yeah we can definitely pump our own. But I don't think the missus will. So I moved the green round tag they put over your fill ports that says DIESEL ONLY from my car to hers.

How difficult of a job would you say it is? Hardest part for an ALH is getting the engine mount out, otherwise easily a day project. Similar difficulty/time?

If you have diesel geek timing belt tools kit, it will put your mind to ease. I have that set for my old 2011 JSW, my friend who did the CP3 and TB at same time, he said the tools I gave to him as shown on the link below made his job effortlessly easy.

Doing my TB on my old 13 took me 6 hours. I imagine the next time (if I hadn't sold it back to VW) would've taken half of that. I used the Metalnerd tools.

Here's a tip I wish I had before doing my TB: make sure the car is in neutral before starting any work. I forgot, had the fuel lines disconnected, turned the ignition on to shift, and diesel squirted everywhere. I ended up pulling the shifter boot and using the manual release to put the car in neutral.

Timing belt definitely doesn't sound too hard, I'll have to invest in the metalnerd tools when it gets closer to that mileage.

What about fuel addative? I run either power service or liqui moly diesel purge in my ALH, can the same be said for the common rail engines?

Yes, power service is a good choice. And a good idea with the common rail fuel injection system (in my non-professional untrained opinion)

The water pump was leaking at 53,000 miles, coating the timing and serpentine belts in coolant, vw covered everything under the power train warranty.

Coolant clogging has been an issue on 12-14 NMS, I'm skeptical about the same issues on '15.

On a recent 1600 mile highway run the wife allowed me to geek out and I used Torque to view the PIDs of our '15 SEL. Charged intake temps were constantly 200F and peaked around 280F climbing long hills in western VA. That's gotta be murder on the coolant for the W2A IC, yet there is no designated change interval.
