#220 of 246 TDI Sportwagon 2012 Answers about Temperature Control [tnt2k03]

Congratulations on your new TDI , I bet it is a blast to drive. That's the way to warm it up too , to drive it... But of course, driving with a frosted window (or a pile of snow on the roof) is ill-advised and illegal.
VW has included an electric heater for defrosting the windshield - it will turn on when outside temp is >80 - also it may be mandatory and/or wise to use 100% defrost position if any frost on windows. It does not get super warm but it does defrost enough of the window within a couple minutes.
The temperature control (digital controls as well as manual, if available) *should* remember the heat setting, the number dialed into the electronic control. If it does not remember, then it is broken and dealership will fix it, end of story, no wiggle-room. However the other aspects you describe are not really fixable, they are design aspects as you astutely suspected; they are the same reason the vehicle gets fantastic mpg.
My experience is with 4 TDIs from 2003 -> 2006. I understand the new ones are similar in with regard to HEAT IN THE CABIN or LACK THEREOF at crucial times such as mornings when my driveway was actually colder than the day's high-temperature on Mars.
In super-cold climates, my jetta/NB/jetta-wagon would NOT warm up without driving it a *bunch* and HAMMERING IT on the highway. That happens to exactly fit my driving style, but my TDIs remained amazingly slooooow to warm up.
Advice: Do not over-rev but keep the engine in a lower gear if you must to keep it warming better. Turn on every heating element. Crank rap music with the bass turned all the way up. Do whatever it takes to draw current and make the engine/alternator work. But don't max the fan too soon! The defroster-electric-heater has massive current draw too - it will run automatically with controls as above, until coolant reaches certain temp.
My 2005 Passat TDI was heavier/bigger-engine and warmed up a bit quicker. 10 minutes instead of 15. Either not quick enough for my preference. It will cool down in cold weather idling in traffic. This is a fact of the diesel engine's efficiency, less "waste heat". Also you have observed correctly that in frigid weather the only way to get the engine to warm up a *little* at idle is to turn on every electrical accessory, especially every heating element, and to ensure the built-in electric heater is operating (put temp knob >80 , defrost-only position if any frost on windshield).
Especially without a garage, a diesel engine in cold climate can be troublesome and cost you time every morning morning. And the bunwarmer "option" in the seat is not truly optional in cold climates. It's good to have, but in the end it can results in part of body being way too hot and other parts being way too cold.
There are electric oilpan & other heaters that can pre-warm the oil/coolant/block. One type is a "dipstick heater". I think can be added without much trouble but not sure of dealer warranty. And not sure if running a 3prong heavy duty extension cord is your idea of fun. Costs more time and PITA. But if you google to fred's tdi club you can read about the heater options.
After 400k on diesels, none with add-on heaters, I do appreciate the heat now by driving gasser Cruze 6-spd in winter... So one of the best things about it has just the right amount of 'inefficiency' which gives it a "lousy" 34 mpg instead of 44 mpg (or more) for a TDI. Yet still strong enough (barely) for real highway acceleration & speeds. It is warm in less than 2 miles of rural road on my commute - miles before I reach highway. With the TDIs, they would not get *hot* until >10 minutes of highway driving the highway. On the coldest days it would take TDI 15 minutes or more of highway driving to get to full/optimal engine temp. Noticeably worse mpg at the cooler engine temps too... But always way better mpg than the similar gasoline vehicle.
Best wishes & Stay Warm!

Thank you for your advice and very detail explaination. I think my heating control is broken. It does not remember the setting when the fan turn off for awhile. I will need to bring it to the dealer. Other than that, the car runs fantastic. This is my first diesel car, and I can hardly tell it is diesel. It runs very much like the gas engine with 50 mpg on the high way. Thanks again for your help. Have a very Merry Christmas.

Thanks Tung and you are very welcome - Merry Christmas!
I hope the warranty service is top-notch like the local VW dealership to me. Let us know your results and enjoy that 50 mpg.
To find some warmth, you can drive from Boston to Jacksonville with just ONE refueling like I did *many* times in a VW TDI.
#223 of 246 Extended Warranty
Jan 21, 2012 (7:04 am)
I just purchased a 2012 TDI Jetta Sportwagen and so far I'm in love with it. First time I've had heated seats in a car. Such a relaxing feature after a day at work.
I switched from Liberty Mutual auto insurance after they quoted me $117 per month, an increase of $35 a month on the 2005 Sienna/2000 Impreza combo we were insuring. There was no other explanation than minivans are cheaper to insure than cars. That's after I got a booklet from Liberty saying that the Jetta has an overall better safety rating than my Sienna did. HMMM. Anyway I hooked up with Geico, monthly payments will be less than half of Liberty's. They had a really cheap add on for Mechanical Breakdown Insurance (MBI). Now I'm wondering if I should cancel the extended warranty to 7 years 100,000, I bought for just over $2,000. Anybody have thoughts on this? The MBI coverage is only about $34 a year extra with a $250 deductible. Bumper to bumper coverage on anything but routine maintenance.
Now I'm just hoping that taking the rear wheel off our tandem bicycle to fit inside the Jetta won't be too much of a pain. Hoping to avoid that roof rack transport.

If I were you, I would not pay for the extended warranty. The warranty is just a peace of mind. Extended warranty is up the person. Sometimes, you feel safe because you have the warranty. If they sold me the extended warranty on top of the manufacture warranty then I would buy it. You see the first 36 months is already covered by manufacture warranty. If something goes wrong with the car the first year or so you would know it.
About the safety, I can tell with my personal experience. I like mentioned at the top of this thread. I bought the 2012 Jetta Sportwage TDI. Well, about 3 weeks ago, someone rear ended to my new car at the speed, probably 50 mph. Totally damaged the back of the car all the way to back seats. My two sons sat in the back seats. They were ok without getting killed. The car absorbed most of the impact energy. We were very lucky that we didn't get killed by the accident. The vehicle that hit my car was toyota 4 runner. So, my new car is now being repaired. I will be driving a new car with a history of accident. I don't like it when I think about it. Enjoy your new car. It is a very well built car, and good luck.

Don't forget to claim diminished value on the jetta. It is worth several thousand less after an accident. Same thing happened to a relative and they got "
$2000 for diminished value.

It is wonderful. On rainy days it makes the interior of the car light and Cherry.
My wife does not like strong sun so the automatic sun screen is marvelous.
It reminds me of the 21 window VW Bus of the 1969 but the TDI has VAROOM!! I bought standard cross bars online Rack.com 69.00 I carry my Kayak and my Sea Snark on top no problem. It nice to look up and check.

Go to your VW Dealer ,GET the TDI. I am of the opinion b/c gas is hard to come
by the GAS station are blending the gas and getting lower MPG. If you keep the Car invest in a set of Nokian Entyres these are quiet and improved my MPG by 10 MPG no joke. If you drive SNOW get the WR.
