I am encouraged (but a tad disappointed) the percentage of fuel stations is 42%. In 03 when I bought the TDI, it was pegged 25% aka 1 in 4 fuel stations. At the time I had absolutely NO issues getting fuel. Being as how the passenger diesel fleet has contracted 33% from less than 3% to 2%, my swag is new TDI owners will have even less issues.

"What was the first year of the high MPG TDI? " At least as far back as 1981... they were built in Pennsylvania (New Stanton) I have some relatives who used to work there.
 
"How reliable are they" Using the design life-expectancy of the engine (given in hours) and some math (assuming 50MPH average speed)....the TDI engine is rated for at least 300,000 miles. Keep in mind this same basic engine is used in marine applications to move boats over the ocean.
 
"How hard are they to start in cold weather?" Not hard at all... STARTING is not an issue at all. (My TDI starts just fine at -15F)
 
"how long does the engine have to run before they start producing heat from the heater?" Depends on many variables. On a cold morning, (-15F) it may take 10-20 miles of driving. HOWEVER, if you turn the heat all the way up... the engine will NEVER EVER come up to temp. because the heater-core can pull more heat out of the engine than it can create.
 
Never owning a diesel, or a VW before, is there anything else I need to consider? Consider adding diesel-fuel additive at EVERY fillup. There are many benefets including 2-4 more MPG, longer fuelpump life and quieter running.
 
Also, do not assume the dealership knows how to effectively maintain diesel engines beyond basic stuff. You MUST use special oil which is not readilly available in North America. (I order all my supplies from tdiparts.com)
 
Unlike Asian automobiles which can be pretty much ignored... VWs are better off when meticulusly maintained per the reccomended schedule.
 
Best of all.... it is WONDERFUL to be able to travel 700+ miles per tank of fuel!!!!

I think you replied to the wrong post -- mine was just a link to an article published in the Detroit News giving the Jetta TDI a very good review. I already have my TDI and have no trouble finding diesel anywhere in my area.

Is this pretty much the case with even the newer models? I live in Chicago area and normally get nice hot air from my cars(gassers) in about 1 to 3 miles depending on outside temp. How about weather that is between 0-20F, would it take anywheres near that long? I know there are a lot of positives to owning one but waiting 10-20 miles(15-30 minutes???) for the interior to warm up would be kind of a bummer.

I can't say on the newer ones, but my '00 model took awhile to heat up when it was really cold. Either way, there are electric heaters that can be installed and you'll have instant heat. Just have to plug it in. I had mine on a timer and it would run a couple hours before I left. Car started like it was a summer day. Not a necessity, but a nice option if you really despise the cold like I do.

I have a 04 Jetta diesel and have had several warrenty issues with the fuel system. It took the dealer over a year to finally find the problem. There is a electric fuel pump at or in the tank that was bad. After replacing, solved the not wanting to start problem. Although, the problem has returned. But only happens every once in a while. The only way to start the car is to hold the throttle all the way to the floor. After 20 to 30 turns of the engine it will finally start. Any suggestions?

I have an attached garage so the problem with heat isn't much of a problem leaving from home. My concern would be coming back to a car at the airport parking lot or something and it's mid January, midnight and -10F. Twenty to thirty minutes of barely there heat output would get old in a hurry.

Go to Fred's TDI page and see if there is anything about the fuel pump. I seem to remember that there is an orifice as part of the in tank fuel pump assembly which a lot of people enlarge by simply removing a small part. In the OE configuration this orifice tends to clog.

Well I used the electric heater as a luxury. Certainly isn't 20-30 minutes without heat, particularly if you're driving it. I would say more like 7-10 minutes if it's very cold. Before I put the electric heater in, it took me about 5 miles to start really feeling the heat. And mine was an '00 so I'm sure the newer ones heat up better.
