That's an old motorcycle trick and I think it works. My last new car, that's what I did. Full throttle bursts but NOT to a high rpm, followed by deceleration...maybe up to 4000 rpm at most (gas engine). I did that "right out of the box" and let me tell you my particular car was faster than identical cars I drove (or by owners who drove mine). If not "faster" at least more responsive-feeling.

Have you tried changing where you buy the fuel? The only time my '00 TDI smoked enough to notice was when I bought what I consider lousy fuel. You might ask them who/where their diesel comes from and then go find someone that gets their diesel elsewhere. Sometimes a lot of local stations will buy diesel from the same truck....so you have to check around. Calling a fuel distributor (bulk dealer) can help as well. Tell them you're looking for a low-sulphur, high cetane fuel and see what they say.

I noticed this Forbes article on a www.tdiclub.com web site VW Tops Quality Survey

It seems to be a more "well-rounded" survey, which I like, rather than just statistics about these or those little problems. It's no wonder, with this broader outlook, that VW did better than Toyota.
 
"To get the rankings, Strategic Vision calculated the index based on survey questions about reliability, vehicle characteristics, dealership experience, styling, interior and exterior design and their overall perception of initial quality."
 
when it comes to strictly reliability surveys, I like to look at least 2-3 years in the field before judging a car. Sometimes early production glitches get fixed, so first year record doesn't look as good as second year and beyond---and other times, a car starts out great but problems develop in 40-50K miles.

breakin / never a reason to redline / Re: New TDI [Mr_Shiftright] by elias

that's how i broke in all my Z28s & 05 GTO... I doubt such a break-in added any hamsters to my 06 TDI engine; I think most all the TDIs are laughably slow but very drivable due to torque.
04/05 passat TDI had decent grunt but also a now-apparent design flaw - chain driven oil pump apparently fails on *every* one of the 04/05 passat TDIs, and now VW sells a replacement gear-system instead. it's $2000+ job, and usually not under warranty. !
 
As far as TDI & redlining, i agree there's no reason to ever get close to redline or even yellow line, but seems like the consensus is that it's good to give the TDI a daily blast up to a decent rpm to let it the exhaust "blow its nose" of accrued soot in an old/DIRTY diesel, and let the turbo spread its 'vanes' .
 
for the new/CLEAN jetta TDI diesel, similarly blasting onto the the highway should help to ensure that the DPF can do its occasional cooking thing.

Yes, given your 3rd paragraph, this is really what I don't understand.
 
I have been running 2 cars (03 Jetta TDI 119,000 miles /04 Civic 87,000 miles) side by side (even I will say it is an apples to oranges comparison), for easily... 5 years. Needless to say, the "make up" has been off (glitz and glamor) for a very long time, if it ever was on.
 
Hopefully for obvious reasons, similar mileage (87,000 miles) , BOTH have been completely and utterly reliable. Given both cars' similarities and differences, I have been completely happy with both.
 
The wear items on the Civic are consumed at roughly 2 x the rate of the Jetta.
 
This is interesting in that the Jetta is run harder and faster on the non commute portion and is 435 #'s heavier. I would dare say if I ran the Civic like I do the Jetta, the consumption rate would be more like 3x to maybe 4x's higher !!?? It would also probably be a drag to the 38-42 mpg we now post.
 
One explanation could be "higher" initial quality. Another could be the Civic engineers designed it that way: given that most folks are almost brainwashed about the Civic's quality before most folks even own one.

Given the wikipedia article about VW TDI engines (the BOLD- my sic), I would agree. (msg # 3107)
 
75% RPMS or 3,825 rpms (of 5,100 redline) that would accomplish the goals.
 
(sorry to hear about the $2k chain driven oil pump issue).

Tie Downs Missing? by tennc
Jul 02, 2009 (11:50 am)

I have just taken delivery on a new 2009 Platinum Gray TDI sedan and was reading over the owner's manual which shows four tie down locations in the trunk. My car has two in the back but none up toward the back seat as in the manual photograph.
 
Is this normal for new TDIs or did mine miss out on something that is supposed to be there?

Can't honestly say if they're missing or not, but I have found that VW's owner's manuals are not necessarily the most accurate. There is also the option that they are simply living up to their abbreviation: VW = Varies Widely.

Just wanted to give everyone an update. The trans seems to be reacting faster off the start, just needs some more miles. Only 300 miles so far. Also still on first tank of gas, can't wait to fill er up and see how I did, only knowing its going to get better each tank.
 
I can never get the keys from the wife, as she drives it to work most of the time.
