Definitely shop around. The local dealer in Reno, NV wouldn't deal at all, so I got on the web and found dealers in CO, ID, and Southern NV that would deal. I bought my 05 Passat TDI in Idaho for $300 over invoice and got the 2.9% for 48 months. The Reno dealers excuse was that the cars were being bought by locals for friends/relatives in California, one of several states void of TDIs. Although I haven't had my Passat very long I love it. Only wish I could have got a TDI 4motion. I heard they are available in Canada. Does anyone know if that is true?
#867 of 1046 Insurance on a Passat TDI
Jul 17, 2005 (7:12 am)
I purchases a Passat TDI in May. I now have 4,200 miles on her and I have to say so far so good. Car is quick, comfortable and I am averaging roughly 550 miles a tank full.
One thing though: I just got my insurance bill ( I live in NJ) and they price the car at $1,500 ($500 deductible) for the year. My other car is an X5 4.4i ($1,000 deductible) and I pay $1,175. Think the 325 difference is all in the deductible? I also noticed that the car's symbol is 20 while the X5's symbol is 15.

My 2005 Passat and 2005 GMC hybrid PU truck are both $570 every six months. That is with $240 deductible collision & $120 ded comprehensive. That is for So. CA.

Well you can't compare insurance state/state or owner/owner, but the symbol tells you a lot. My Jetta is also a high symbol (18). I have the same deduct and policy on all my cars, and right now my Jetta is about the same to insure as my 2005 Honda Odyssey and 2003 Chevy Silverado. The wife's GX470 is about $100 more/year.
I think the TDI is more because it has a Turbo. I'm not joking.

If it's like my diesel Rabbit (OK, this was a while ago) it is because it is a VW. Everybody knows that VWs are sporty and are driven by people who tend to speed and take chances, right?

Of course! Actually, while my TDI is a symbol 18, a 2.0slow Jetta was only a symbol 15 which is much closer to any other similar car. The 1.8T was a symbol 19. I believe a Trans-Am (at that time) was also a symbol 19. I'm just listing what I remember from when I bought my TDI. I'm old enough to not care about insurance, but was quite surprised when the bill came so I talked to the agent about it. He reassured me he had it right in the computer and he wasn't sure why a 90hp car would get such a high rating either. If they only knew I've bumped mine to over 115hp.....

I had a VW Sharan (mini-van) during a work assignment in Germany and had the exact same problem. I cannot remember exactly what it was, but it is a common problem. Take a look at the diesel board on vwvortex, or perhaps the tdiclub and post a question.
When I had this problem I posted there and got an answer very quickly and the response agreed with the dealer's inspection. Sorry I cannot remember what it was, but it was some type of sensor that would not allow the boost to work - essentially, you are non-turbocharged when this happens. Stopping/restarting the engine resets the sensor. I think it will get progressively worse (start happening more often).
Here is a list of possible solutions from the diesel board at vwvortex - you might want to post a new query tho, b/c this info is from an older post:
Your car is going into limp mode. This happens when it sees too much boost, so it cuts the boost altogether. Maybe fueling too, but I am not sure about that one. It is reset each time you switch off the ignition. Thats why the problem seems to go away upon restart.
There are several things that can cause this. Most likely, the variable vanes in the turbo are sticking in the full boost position (due to soot buildup in the turbo). So while puttering around under normal acceleration, the ECM doesn't see crazy boost levels, so it thinks all is fine. But when you punch it, the boost spikes too high and the ECM shuts it down so as not to blow up your turbo. The best way to see if your vanes are sticking is to try to move the actuator rod on the turbo. There is a vacuum diaphragm that controls it. Look for the vacuum line that goes down to your turbo to see where it is located. If you cant move it by hand, try unplugging the vacuum line from the N-75 solenoid & apply vacuum. Either with a vacuum pump or just use your mouth. You can provide enough suction to move this rod yourself. Make sure it moves freely. If not, lubricate the area with a good penetrating oil.
A second possibilty is your N75 valve has failed. This is what controls your turbo. It is not a common problem, but as with all electrical parts, it is possible it is no longer functioning. You can try to swap your boost control solenoid with your EGR control solenoid as a temporary test. The parts are very similar, so can be swapped to trouble shoot, but they do have some differences, so it should be used only as a test. AT least it will save you the cost of buying a new N75 valve if it is not the problem.
A third option is that your intake is plugged, restricting the airflow. this restriction does not allow the compressed air to move fast enough into the engine, causing the higher than usual pressures before the restriction. This is a common problem here in north america because we use diesel that is more dirty than yours. 500ppm of sulfur IIRC. But since your diesel over there is supposed to be much cleaner than ours, I do not think option #3 is your culprit.
Try to see if either of the first two help out & well go from there. Oh, one other thing. Before going through all this, contact someone who has a code reader or Vag-com to get the code stored in your ECM. It will probably read something like 'Charge Pressure Deviation' or something similar. If you can't contact someone who can retrieve the code for you, you may have to go to the dealer. Some will do it for no charge (it only takes 3 minutes), some will do it for a nominal fee, and others will charge a full hour labour to do it. It depends on the dealer & how customer friendly they are.
Good luck & let us know how it goes.

Thanks for your response. Thrust sensor did not correct the problem, and 2004 Passat TDI is back at dealer. I printed out you info and will pass it on to the dealer. The problem occurs mostly on hot days, temperature greater than 85 F.
#874 of 1046 Question about increasing low end power
Jul 22, 2005 (12:37 pm)
I am interested in buying the the TDI wagon so I test drove an automatic TDI sedan (wagons only come in automatic). The only thing that concerns me is the <1900 RPM power. Whether you floor it or gently press the accelerator, you accelerate VERY slowly until the turbo kicks in. Is there anything I can do to fix this lack of power? It didn't feel like the engine was struggling or anything but was just some sort of computer setting. Would a chip fix this?

Welcome to turbo lag. You might find some aftermarket bolt-ons or ECU remapping options that will allow the turbo to spool up sooner but you're probably not going to see much. You could try brake standing...
The nice thing about the TDI is the broad torque range. For comparison, my WRX (gas turbo) does nothing until 2800rpm....but it's also a manual so you can rev and launch.
