I am not aware of theThe coolant migration problem affecting 2004 models. However, since you asked about it.... Here is some info with photos clearly showing the "coolant migration problem".
On your 2004, I would suspect that you have the ol' internal leak in your EGR-cooler. With this problem, the antifreeze will go down... with no apparent leakage. I beleive VW has been replacing the faulty EGR-coolers at their expense.
To answer your question about what is G12 coolant... the designation "G12" is the VW specification for the antifreeze. Never put in ANYTHING but antifreeze that says "G12" on the bottle.
Here is some info about the various VW antifreeze types.

I have a 01 TDI GLS-it's an great car, but be prepared to spend alot of money on maintenance. I estimate that my maintenance bills run about 1500-2000 a year, twice the amount of some of the bills I've seen for regular gas engines. I've had some pretty serious problems in the past 2 years-glow plug, alternator, sensors, power steering... I wouldn't recommend a TDI if you don't have access to a diesel mechanic outside of the dealership. The dealerships are okay to use to standard maintenance, but the second the warranty goes out-be prepared to have $1000 repair bills. I would do some research and see how many mechanics around you are willing to work on a beetle diesel. Down here it's very hard finding one-even in a city as big as Houston.
I get great mileage, and I expect to drive the car until she hits 250,000+ miles. It's a good car to have when you plan to drive it for 15 years.

I repaired my mass air flow sensor two weeks ago. I also had to replace a glow plug about 2 years ago. Keep an eye on your alternator (and pulley)-I have fixed that as well. If your alternator pulley goes out, it will take your power steering pulley and pump with it.
I'm in the same boat you are. I cannot afford all these repairs-but I am dreading another car note. The only thing that I can think of (for me) is to drive it until I can afford another down payment and get a normal gas engine.
Unfortunately, I will not own another TDI-the maintenance and costly repairs have dimmed my passion for "German Engineering"
Good Luck!

best wishes, alison6. i think you will probably find that non-german and non-diesel cars also require maintenance and repair at similar times/miles as your TDI did, and for similar costs.

I agree with you. The TDI engine actually has lower maintenance costs than the same VW vehicles wih the gasoline engine.
For examples,
*)Engine-oil is changed more frequently in the gasser.
*)The gasser has sparkplugs and wires to contend with.
*)Fuel costs are higher with gasser.
Virtually all engines have a timingbelt to be replaced. The parts/labor cost is identical reguardless of fuel-type.
In fact, I cannot think of any scheduled mantaince on the TDI engine which costs more than the gasser over the lifetime of the vehicle.
...and being able to drive over 800 miles per tank of fuel with my TDI is priceless!

Only comment is virtually no Japanese made new car has a timing belt; just about all have gone back to chains especially any new 4 cylinder.

Actually an interesting conundrum. You might want to check the techincal data for the sunset mileage (point) for the timing chain, the cost and the most likely cost in damages if the timing chain should break. Look for app 175,000 to 225,000 miles. This is good news if you plan to keep the car for less than that mileage. Certainly it gives an upfront advantage in not having to do a timing belt change at app 105,000 miles.
I used to be pretty dead set against timing belts (fiber) in 4 cylinder engines. So much so, for a lot of years refused to get a 4 banger with timing belts. However with the TDI, it presented an advantage of 44-62 mpg, but had the obvious disadvantage of a timing belt change at 100,000 miles. To boot there is a lot of evidence in the field that a lot of dealers really do not do this procedure well and charge a lot of money. However the design longevity of the motor is 25,000 hours at 80% loading. At 40-50 mph average this translates to 1,000,000 miles. So if one wishes to keep the car (engine) longer than 175,000 to 225,000 miles you have a 100,000 mile renewal interval and at a known cost.

I have already posted what sounds like the same problem. I have been to a mechanic who told/showed me the fuel lines vibrating. It begins as the car warms up and yet the fuel pump is working fine. He has seen this in a 98, and after replacing the charcoal filter, fuel pump, and one other part, found it didn't solve the problem. The VW dealership had no other thoughts. Sorry, I, too am looking for a solution, before trading this piece of crap in.

Do you have a link to a website or publication that confirms the fact that the motor is designed for 25000 hours at 80% loading?

No! Indeed this is almost better than a US goverment classified top secret! Have you EVER seen this for any GASSER!? I had to ferret this out by reading posts by some of the VW repair guru's www.TDICLUB.com and by talking with them as I had opportunites to meet them, as this figure and information is truly arcane.
