After all the hand wringing and second guessing on VW's bizarre oil ratings for the 2006 Jetta TDI, it seems to me that after 1000's of Oil Wars Forum posts on the subject from people, some who have had to rebuild the problem prone cam shaft and all it's little bits and pieces, that it's actually best not to use ANY of the VW recommended oils.
Unfortunate VW owners have spent piles of cash in expensive top end re-builds in cars that used the VW recommended 505.01 oil since new, with no guarantee
that the new cam, bearings and lifters will last any longer that the old ones,
I think VW is just hoping all the old PD 2005.5/2006 BRM engines will all quietly wind up in the crusher soon and everyone will forget about that embarrassing little experiment.

many well-informed TDI owners have come to the opposite conclusion as you, longo2. We say it's best to use only the oil that meets the VW specs. Seems like it's a very small % of those 05.5/06 TDIs that have the "soft camshaft metal" problem.
It was just one bad batch o camshafts, according to all the data I've seen, including that from the local dealership which services thousands of TDIs and has only seen one with the "dissolving-camshaft". but hey, they could be lying to me I suppose :|

i was thinking that the "exhaust flap" would be covered under the 48000 mile drivetrain warranty, not the emissions warranty.
I understand that "exhaust flap" is known also as the "anti-shudder valve" and is important for safety , such as to prevent the engine from running forever after the key is turned off.

Well that's not a drive train part though.
#4083 of 4777 Check Your Emission System Warranty
Apr 01, 2010 (11:28 am)
You should have received a separate emissions warranty booklet listing the covered components (and their parts). Emissions control components often required by state law to be warranted for considerably longer than the typical 50-60K mile drivetrain warranty. In California, its (IIRC) 70K miles/7 years. YMMV for other states.

yeah, i think i was off-base on that exhaust-flap being same as "anti-shudder valve" - currently I understand that exhaust-flap is something very different. it also sounds somewhat "optional". (I understand my "dirty-diesel" 06 doesn't have an "exhaust flap" - it's only the DPF/newer/CR models which have it in USA.)
The folks on Freds are more knowledgeable than me about these things - they are rather adamant that the emissions warranty should cover exhaust-flap if it fails before 80k or 100k. They recommend filing a complaint with EPA/NHTSA if VW doesn't cover it under the emissions warranty.
Additionally I would file a complaint with VW "zone office" if they don't pay for "exhaust flap" under emissions warranty - make sure it gets to someone with a title resembling "zone office representative" for your region.

From what the dealership said, the car will run fine without this part. As many have mentioned, it is part of the Exhaust/Emissions functionality of the car, so it does seem that it should be covered under warranty. What does it say in the Owner's Manual of the vehicle? I currently don't have access to it to review. Once I have the opportunity I will be contacting VW to find out why this part wasn't covered. I recall reading something about the emissions being covered for around 80K...
This link is a bit old, but might still apply?
* Emission control and emission related parts are covered for the
first 2 years or 24,000 miles of vehicle use; and
* Specified major emission control components are covered for the
first 8 years or 80,000 miles of vehicle use.
Since I haven't owned the car for two years, it is well over the 24K miles. For the second bullet, the question is, is this part "major"? It is certainly expensive....

Run it without! Might improve mileage! Spend the $500 on GOODIES for VW!

Major components, covered by the Federal Emission Warranty and as mentioned in one of the previous posts (and according to VW ) are:
engine electronic control module (ECM)
on board diagnostic device (OBD)
All above 8 years or 80,000 miles
There is a disclaimer though, damages caused by tampering, use of improper fuel, abuse, neglect and improper maintenance are not covered by this warranty. This, probably written by a clever attorney, may mean just about anything and could be interpreted into one's advantage (or disadvantage).
It never hurts to ask the VW service manager to double-check with VW N.A. and double-check his "check" ... i.e. yourself calling tech support at VW N.A. and check with them directly.

The key is: Does the part affect emissions, and is it available from an aftermarket supplier? If the car runs fine without it and it is just for emissions, I would not spend my $500 repairing it every 45k miles. I am sure there is a lot of crap on cars today that are only there for emissions. In CA there is a limit as too how much you have to spend to keep your car up to standards.
