A well-broken-in TDI engine can achieve much better than your 40.2MPG you are getting on a new engine.
The TDI engine takes up to 30,000 miles to 'break in'. During that time, if properly managed, you can expect the piston-rings to seat and compression readings to go up and level off.
I was meticulous when I broke-in my TDI. I took measures to ensure the cylinder-walls did not "glaze" before the rings seated. (Once glazed, the rings cannot wear-in to the cylinder-walls and your MPG will not go up any more)

Would you buy this car again? How are the engine noise and road noise?
Does the exhaust smell bad? I had a Ford pickup. Whew!
We'll be using it for city driving mostly.

Would you buy this car again? Absolutely! Infact, it is my wifes car and she would have nothing else to the point where she decided to invest in it (repair it) because there is nothing comparable on the market.
How are the engine noise and road noise? We have used TDI to make many roadtrips (over 12 hours) Once rolling over 10 MPH along, it is impossible to tell it is a diesel.
Does the exhaust smell bad? I just asked my wife that question... her answer "I dont know, I never really thought about it"
For me personally, I notice the difference in exhaust odor based on what fuel is being run in it. For example, Biodiesel (Corn oil, Peanut oil...etc) smells kinda like popcorn.
I do have to tell you that the engine is SOOOO efficient that it does not produce much heat. In the winter, when ambient temps. are below 10F, Do not expect much heat out of the vents for the first 10 miles of driving. HEATED SEATS ARE A MUST WITH TDI.

How do you breach in the TDI, glazing???, just purchased one and love it so far but want to do right by it. Thank you

You are correct to be concerned about "glazing" of the cylinders. If this happens before the cylinder-rings are seated, your engine may never achieve full MPG and power.
It is important to understand that a TDI engine continues to seal the rings for many thousands of miles. (as evidenced by compression-measurements)
The general concept of ANY engine break-in is to put the piston-rings under pressure so they are forced against the cylinder-walls.... followed by a cool-down period. This translates into short bursts of FULL THROTTLE ACCELERATION followed by DECELERATION. The decel. portion of this is imperative to allow the rings to 'rattle' a bit in the ring-lands.
I hesitate to attempt to describe the complete break-in procedure here because I am not the one who did all the work of compression-testing and evaluation. Please visit Freds TDIclub to get the facts from the source. The "TDIFAQ" section answers nearly every question ever asked about TDIs.

If you recently traded in a gas guzzler for a more fuel-efficient new vehicle, a reporter wants to talk with you. Please email PRedmunds.com no later than Friday, April 13, 2012 with your daytime contact info and the makes and models of the vehicles.

I drive an '07 Jetta 2.5, my fourth VW, and it's been as good a car as I could have hoped for. Still, I'd like a TDI, mostly because I find the diesel technology fascinating (I owned an old non-turbo diesel in the 80's, but that's another story.) My commute is only 15 miles each way, and I total only 16K miles per year. As such, I don't want to incur some of the big repairs (hi-pressure pump, etc.) because my fuel savings won't offset them. SO, how common are those expensive repairs? If I maintain the engine from new, can I expect 100-150mi. without the big ticket repairs?

I think your goals might be WAY too low. So it is really the perfect reason to stay with your 2.5 L or use the reasoning to get into a TDI. So the real question given the issue of fuel savings is how many gals and or both dollars can you save in 120,000 miles. Figure 40-42 mpg on the current Mk 5 TDI. Fueleconomy.gov lists 26 mpg for the Jetta 2.5. (2927- 4615=1688 gal saved 4.15= $7,006) 120,000 miles is the first "major tune". That consists of a timing belt and water pump replacement. Now this is fairly technically exacting from a DIY perspective, so make sure you use a local guru, GTG guru or independent shop that specializes in TDI's. In your case, you can expect to come up on it app 7.5 years. I have 175,000 miles on a 9 year old MY Jetta TDI. I have had little to NO unscheduled repairs. Yes, it has had scheduled maintenance (20,000 to 30,000 oil change intervals, air filters, etc). It has even had a few TSB's. One UN scheduled repair was a drivers side headlamp going out. $8.0 to R/R. I just recently had two brake lamps go out. Dealer R/R no charge, lams are what 2 per? I had to replace a windshield, rock out of nowhere. Tires were changed 112,300 miles. I swag 250,000 miles from the rotors and brake pads. Resale historically has been higher for the TDI over the gasser, but specific dollar amounts are not guaranteed or guaranteed to continue.

B, Your ?'s about the latest diesel's seem to be quite dated. I have been driving the VWdiesels since the 70's. The new cars do not smell. They don't smoke and they are quiet. When gas goes to 8.49 a gallon in a couple of years. These cars will be sought after. GM and Ford already have cars and trucks like these but just don't sell the in the US, Yet. The Chevy Cruse diesel will be sold here starting in 2013. 50 mpg. It's being sold in Asia and Australia, India etc etc. So, Yes I would buy it. Heck we just bought a new 2012 VW Passat. I filled my 1st tank of fuel 6 weeks after we bought it. Neat

R, You da' man. 175,000 and still going. An inspiration.
