I'm the same, this is my first diesel as well. Was the light flashing when it came on, or was it solid? Mine was flashing when I was driving, so I pulled over and called the 24 hr roadside assistance at the dealership's recommendation.
 
Hopefully all will be well and this will be the only trouble you have for many years to come. As someone said to me (sorry, I can't recall the name) at least it is under warranty and will be fixed.

I am going to be travelling to Montreal to visit McGill with my son. Taking the new Jetta TDI. Can anyone give me the skinny on the availability of ULSD fuel in Canada.
Thanks

You should be good all over Canada. Same rules as here.
 
What is ultra low sulphur diesel fuel?
Ultra low sulphur diesel fuel (ULSD) is fuel that contains less than 15 parts per million sulphur. It is usually used for on-road applications. Since Sept. 1, 2006, all on-road diesel fuel in Canada must be ULSD.

Reminder: what to do when Oil Light illuminates solid by elias

Pal who I sold my 05 Passat TDI just had oil-chain/oil-shaft shred in stop & go highway driving. a SOLID OIL PRESSURE LIGHT (hello) was his first indication, but he didn't believe it, thought it was probably a sensor failure, so he drove it for 2 miles, then restarted it twice. :| If this was a warner-bros cartoon and he and I were both mice, I would slap him silly like those two cartoon mice. But no - the results to his ex-TDI are punishment enough.
So a warning to B5 (04,05) Passat drivers about this double-secret non-maintenance-item - OIL PUMP CHAIN -
The 04,05 Passat TDI requires oil pump chain/shaft inspection and maybe replacement every 75k or it is likely to shred. This is not mentioned in the manual for the car, as far as I know. TDIs are especially great cars in my experience, but here is an example of the special care and feeding a TDI requires, especially the uber-rare 04,05 Passat TDI.

A light suddenly goes on! This is what I like about GAUGES. Before this lite went on,there was probably some fluctuations in oil pressure that would have shown itself on the GAUGE.
 
    I 'lost oil pressure' once. The wire fell off of the sending unit.Reconnected,and good to go!

My MIL came on around 350 miles. Took it to the dealer. After keeping the car for nearly two days, here is what they had written in the sheet:
>>>>>
Scanned system for faults. Found code for Cylinder #4 Glow Plug circuit Q13 electrical fault (P0674). Called the Tech Line. Advised to perform guided fault finding and transmitted it to tech Line. Checked all connections, fuses etc. All OK. Advised to clear code and retest in AM. Retested next morning. Fault came back. Called Tech Line. Advised to swap 3 & 4 glow plugs and clear code and retest. Cycled key approx 10 times. No light at this time. Let car sit to cool off. Retested again. At this time the light is off. No codes have returned. Tech Line advised to release the car at this time. They advised to bring the car back if the light returns.
>>>>>
 
My take: No real diagnosis here. Having enjoyed outstanding reliability from my previous Toyota, Honda, and Acura cars and suffered the pain of unreliability from a Chrysler Town & Country minivan, I have my fingers crossed and am hoping I did not make a wrong buy. The car is truly a blast to drive so perhaps that needs to be seen as the offsetting factor against any reliability issues.

Yes, it's true when you absolutely enjoy a vehicle you can put up with little issues more. What really sucks is when you buy a boring but alleged reliable appliance...and then IT has issues. I gave up buying based on reliability many years ago. But I digress.
 
On my prior TDI, I would get an erratic MIL every once in awhile. It was almost always a glow-plug code, yet even with the light set, the car would start perfectly fine in the dead of winter. I'd reset with my VAG and go about my business. Sometimes, just cleaning the contacts of the glow-plugs would reset the light on it's own. Therefore, I'm of the opinion that the glow-plug sensor's are just ridiculously sensitive. This happened maybe twice a year. The good news is that it's just a glow-plug so in the scheme of things not much to worry about.

A second from this neck of the woods and winter here has been a COLD 68 degrees!? GEEZ makes one crave more global warming! I had a so called slow up to temp issue and the VAG.com codes indicated either glo plugs/thermostat. It turned out a change in thermostat did the trick.

Edmunds purchased a long term tester of the new Jetta TDI. Where is the blog of what they're doing with it?

I agree, it doesn't sound like the problem is truely fixed. Hopefully this will be the last of it for awhile, I feel the same about questioning the purchase after having problems this early on. Right now I have 1300 miles on (will be over 2000 by the weekend) and all has been good since the fuel pump relay issue I had earlier.
