#2532 of 2551 TDI break-in [crazycat2]

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

CW, I love the smell of Diesel in the morning. Just sayin' All kidding aside. The other posts here are right. Modern TDI powered cars don't smell much. Sure, There is some order filling up at the pump but you get that with gasser vechicles.

There won't be any more diesels sold in N.America than the car/oil companies can keep out.
They will kick and scream and use their P.R. hacks and lobby money to stall and add more rules to keep Diesel Cars from getting a bigger market share.
Remember the good idea T Boon Picken's had a few years ago about using more natural gas engines to get off the gasoline habit? He might as well have been talking to rows of fence posts...
Why so much resistance? I think it's because they can't market ETHANOL to diesel or natural gas vehicles owners.
This Govt. mandated poison in your tank gives you less power, worse mpg's causing you to buy more fuel. The Huge Multie National companies that are now in the game, and the Govt, hungry for the extra fuel tax million$, love that.
My old 06 TDI (using NO Ethonal) costs me half of what my gas cars used to for the same trips..
Last week there was a proposal to drop the mandate for ethanol in gas for this season due to the drought and poor corn crops over many states.
That good idea got killed before before it took it's first breath.
Call me paranoid, but I will believe a 50 mpg Chevy Cruz with a diesel engine when I see it, if I live that long.

I would imagine a big part of the higher priced gas is higher priced ethanol without as many subsidies. Although I think they have cut back to the 2.9% mandate with the subsidies gone. I get better mileage this year than last. I cannot think of any other reason. Only about 1.5 MPG better with my 08 Nissan Frontier. Would be nice to have the same truck with a diesel engine getting 30 MPG.
