Do not forget that the 2005 TDI is a COMPLETELY DIFFERENT ENGINE than the 2003. The "pumpe duse" engine has seperate injector pumps for each cylinder which are driven from lobes on the camshaft.
In any case, the problem described is ABSOLUTEY somthing wrong with the engine. The "pumpe duse" engine is supposed to be CLEANER than the previous engine.
try standing on the accel when someone is gatoring you at night, especially after cruising for a while - you WILL see quite the smoke cloud in their headlights as you dust them. unless maybe you are burning california semi-low-sulfur diesel. and the PD/2005 in my passat is definitely cleaner than the 2003 TDIs, noticeably less smoke. but still some.
But I have heard of a few turbos actually failing early in the warranty period. If you're going to have a turbo failure, that's the best time for it to happen.
For a healthy turbo over the long run, here are a few suggestions:
1) Don't lug the engine. Don't try to accelerate quickly from below 2000 rpm if you're in 3rd gear or above.
2) On those long uphill climbs, just because you CAN accelerate past slow-moving gassers in top gear, doesn't mean you should. Sometimes near the crest of a high mountain pass, the grade suddenly gets a lot steeper; that's a very good time to downshift.
3) Exercise your turbo regularly. Freeway on-ramps are a good place to wind it out to 3500-4000 rpm or even higher. Cruising at the legal speed limit is good for fuel economy, but you shouldn't baby your engine all the time. The turbo vanes need to regularly move throughout their entire range, or they can accumulate a coating of crud that will prevent them from moving throughout their entire range. And the VNT actuator, a small and very cheap part that CANNOT be ordered separately, can start to stick if you don't exercise the turbo enough. If the actuator fails, you have to replace then entire turbo.
Treat your turbo properly and it should last 100k-200k miles or more. BUT... knowing what can cause a turbo to fail, I think I could probably cause one to fail intentionally in just a few hundred miles.
This is often the cause when a warm TDI engine won't restart. But I suppose it can happen to a cold engine, too.
Can you provide any additional feedback on your issue?
This part was updated in 2000-2001 and I believe you can tell which is which by the color. The new ones should be gray in color. If yours is black, it's very likely the problem and worth swapping out as they're cheap. Buy one here World Impex or at the dealer.

It's not easy. You need VAGCOM or other VW software to start with. The big question is, why do you want to?
As for rotors, experience says it is not wise to use cheep rotors. The cheep ones can rust, warp and generally need replacing before they actually wear out.
QUESTION: Why are you looking to replace rotors? Are the originals actually worn out?
I have been hearing a lot about the reliability issues of VW’s and poor customer service. On some sites, all German auto engineering is in question.
Does anyone have any hard facts as to the percentage of VW TDI’s sold that have problems? Is it on average with other auto makers? Can anyone tell me of a web site to find reliable information on this question?
This is not a criticism of anyone or any forum, but if you read the forums long enough it is like watching the evening news: You only hear about the wrecks/problems and not about the other 99.999% who made it home safe/have no problems.
PS
look for TDI clubs on line. They are quite active and have very useful information.
The VW dealer here (mid Vancouver Island, BC) has ordered replacement strips under the warranty.
He had no idea when they might start taking orders again, but figured it may be close to the end of the year, maybe, big maybe.
I wonder if any of the other auto makers, Honda, Toyota, etc. are looking at this and thinking that maybe there might be some market for a high MPG diesel? :P I guess time will tell.

I too would like to know if there is a way around this.
I've had a VW TDI Beetle before this and only had to replace tires in the 60000 miles I had that. Traded it because I needed more room.
It is hard to compare to many other cars not equipped with 24/7 DRL's. The other DRL equipped vehicle went out app the same number of miles but at the 5 year or 60 mo mark.
Thanks
By the way, what is the best place to find used Passat TDI Wagon here in US?
Thanks
The real culprit is high sulfur diesel fuel, which in theory should abate the structural problem when they finally enact the 2006 low sulfur fuels standard. Probably sometime in 2008 !!? CA uses a bit lower sulfur fuel so the problem is not as acute in CA diesel run cars as in the other 49 states.
The next thing you can do to slow down the build up process is to get the EGR modification. There are also after market EGR filters but you might want to research this a bit better to see if it meets your comfort level.
While it is the oem recommendation to change out the expensive fuel filter at 20k miles I have been on a 65,000 mile fuel filter interval. I use an additive Primrose 405/c and have not experienced either the carbon build up or fuel problems due to fuel filter issues, such as: hesitation, water build up, dirty injectors, algae, etc.
Lastly there is some anecdotal evidence that running the TDI engine at too low an rpm predisposes an engine to this carbon build up condition. Might that be true in your case?
Good luck! Let us know how you make out!
Me thinks you have crappydealeritus.
Does the car start or do you have it towed in? Can the dealer reproduce the problem? I think this dealer is just throwing parts at it and when it starts he assumes all is good.
The car has to be towed. I'm not sure what the dealership is doing to diagnose the problem. I think you are right with your observation that they are just grasping at straws and really aren't sure what the issue may be. My thinking is that this will be the last time I have these people work on the car. My goal is to find someone who knows diesels better than this dealership. I will try the Primrose 40S/C additive suggested in another email and post another message looking for a mechanic in RI. Thanks.
