This is all relative. In cold weather (-5 to 15 F), my '03 Golf TDI would take 10-15 minutes before the heater would blow anything other than ice cold air. The warmer the ambient temperature, the less time it took to warm the interior. My '89 NON-turbo diesel Jetta would never heat up in cold weather like that.
Regarding future availability of TDI Passats, we can look to the past. VW imported their B4 Passat TDI for the last two years the car was sold in the USA, 1996 and 1997. And nothing until '04. I would assume there will be no problems with getting an '05 Passat TDI, but I'm not expecting the next-gen Passat to be sold in the US with a diesel. There were many people who waited for the B5 (1998+) Passat diesel, but they waited 6 model years.

Yes, on the subject of #2 diesel availability, it was a passing concern of mine before getting a 2003 Jetta TDI. Any where that I have gone, (31,000 miles) I have NEVER once had an instance where I did not or could not get fuel. Some numbers indicate that diesel is sold at 1 out of 4 stations.

Yep, and regarding your first paragraph the same is true of a gasoline engine.

I don't have any experience with TDI but on our Ford 350s with the Power Stroke Diesel we have an attached unit that kicks the engine idle up to 1200 rpm. The manufacturer claims that they should idle at that rpm range to keep warm enough in extreme cold temperatures. At 40 below they don't heat up as fast as the one gas PU we have. They last a lot longer before overhaul. Our service vehicles idle 12 hours a day in the winter. They may get 10-20 miles of driving in that period. Gas engines do not hold up under those conditions. I was against diesel until I experienced the difference in longevity.

Are you saying that a diesel takes no longer to warm up than a gasoline engine?
If so, this has not been my experience. Me and a friend tested this one day last winter. It was a very cold morning (5 F) and my Golf TDI and my friends Jetta gasser had be sitting all night. We wanted to see what the difference was in time to heat the passenger compartment. After going 6 city blocks to reach the freeway entrance, my friends gas powered Jetta was already throwing warm air. After 1 mile on the highway it was blowing hot air. It took another 7 miles before the TDI blew anything but freezing air.
To say that a diesel and gas car will take the same amount of time to heat when very cold is misleading to the folks reading this forum.

If the expectation is for the diesel equipt engine for the heaters to heat as fast or faster than the gasser, you will be disappointed.

My Jetta takes four miles before hot air begins blowing. Most of my gassers take about two. This is starting up, about 1/2 mile of slow speed driving and then 55-65mph country road driving. If I plug in my TDI heater, then the temp guage goes straight to 190F and heat blows immediately. If I drove short distances or just around town, I likely would not drive a diesel. The gassers will heat-up just sitting and idling where a diesel will not.

So in essence it's taking about 9 miles before your buddys TDI even blows warm air? He better have it checked out because mine takes about four miles. If I'm working in my home town office, my entire drive is only ten miles. My TDI is completely heated and I've turned the heat down to low at about the six mile mark. This was before I installed a TDI heater which gives me instant heat. Are you guys testing this using the method explained in the owners manual for maximum heating?
Another thing I've found is that I don't turn the blower on until the temperature gauge starts to move upward. If you're running the blower hard right off from the start, you'll actually delay heating a diesel because you're moving cold air acrossed the coolant. You can also insulate the coolant pipes in the front radiator to help keep the cold air from further chilling the coolant.

If you live in a cold climate I cannot imagine you would park outside and not plug your vehicle in. Especially overnight. It is much easier on the battery, starter & engine. Then as has been said you get warm air immediately.
#389 of 1046 Will There be 2005 Passat Diesel Wagons or not?

Does anyone know the real story about the 2005's? Will there be TDI's for the 2005 Passat wagons?
