Consider yourself officially informed! The TDI battery is essentuially the most powerful LA battery that can fit in the battery-tray. The "gasser" volkswagens come thru with smaller, less-powerful batteries. (less lead = less weight = lower freight charges to ship the vehicles over the ocean.)
 
NOTE: Most batteries are priced such that the COST is the same for a given "grade" battery. This means, people with "gasser" VWs can ask to have the TDI battery installed and the COST will not be any different than installing the origial-sized battery.
I have done this on virtually every "gasser" VW I have owned since my 1979 VW Scirocco.

I agree with you... the ONLY time I have seen need for a fancy AGM (Odyssey) battery was in a vehicle modified for drag-racing. To reduce weight and gain space for the turbocharger-plumbing.
 
I found it amazing that a battery smaller than my motorcycle-battery could start that engine.... but that is the magic of a $230 battery.
 
Personally, I will stick with $80 LA batteries in my road-going vehicles. They last over 5 years even thru Vermont winters starting the engine at -15F.

For VW/Audi xmissions, many people have "experimented" and found that the original G070 fluid is the VERY BEST in those xmissions.
 
RedLine MT90 comes in a close 2nd.\
 
As for capacity... I do not have the factory service manual in front of me but I seem to recall the capacity is 2L

You could probably power your ignition system with 8/ 1.5V flashlight batteries---but of course not much else and only for a short time.
 
But not glow plugs---they are a heavy draw, which is why they carry a what....80 amp fuse? 50 amps? Something like that. My Benz diesel needed 80 amp fusing.

I have a 2009 Jetta TDI with 6,700 miles. I have now had dashboard warning lights come on twice, the first for emissions and the second, now, for an airbag fault. I live in Colorado, where we just had a freak autumn snowstorm of about 20 inches. The airbag fault light came on around then. I thought the sensor might just have got wet. It was a lot of snow.
 
When I took the vehicle to the dealer for the first emissions light incident, the tech said he couldn't reproduce the fault. He told me that the computer will find what it thinks is a fault, turn on a warning light, and then keeps on testing. If it can't reproduce the circumstance that caused the fault light to go on the first time, it turns itself out. Is this true?
 
If so, I wonder if the airbag fault light is the same sort of thing.
 
Any ideas on how to avoid killing a day with the car at the dealer for every time a fault light comes on and probably doesn't mean anything significant?

Well formulated bpeebles... except:
 
"less lead = less weight = lower freight charges to ship the vehicles over the ocean"
 
I hope that was a joke, right?
 
Ro/Ro vessels that haul cars across the Pond are not paid by weight but per unit/car. Many manufacturers (like VW) have their own sub-contracted vessels and shipping costs are appx $ 150.00 per car, regardless of the weight.

Set of Winter TIres on cheap steel rims by farmertull

I would like to do this through Tirerack.com but they say I have to buy tire pressure monitor sensors. Is there a way to run without them ? I have a 2010 TDI Sportswagon.

Yes it's fine to shun TPMS for the winter- I override it with a small piece of black electrical tape. Tire shops may be prohibited from proceeding like that.
Theoretically you could make a typo and indicate to tirerack that your car was an 06 without TPMS and then they'd ship you TPMS-free tires/wheels for your "06 TDI" that would coincidentally fit your 09 too.

I think it depends on the system being tested, but yes, generally if there is a "one time only" fault, the check engine light will reset. I'm not sure about other types of warning lights however.
 
Quite frankly, if I own another German car, I'd buy a good scanning tool and take care of these warning light resets myself. They seem all too frequent.
