Re: The "real world" test numbers VW is publicizing [whobodym] by ruking1

Actually if you have been following the thread " Diesel in the News" it has been discussed extensively. But some MAJOR issues have been that under intense pressure (some say political) the EPA was forced to change the (almost generation old) testing procedure because Toyota Prius did not get near the EPA 60 mpg city 50 mpg highway advertised. Indeed some hypermilers were able to get this, but the range has been more like 45-48 mpg. Issue two: Indeed Toyota certified the numbers and the EPA went along. This was normal normal, but the boiling water was indeed generated
 
Issue three: This is much more technical than can be sound bited in this post, but it is unclear whether the OEM (VW) posted their tested/certified EPA numbers or the EPA (because it is NOT diesel friendly) actually chose to do the test/certification and mandated VW to post their (EPA's) lower EPA numbers.
 
In contrast, it is the more usual procedure of the oem doing the testing/certification and the epa going along.
 
So to answer your question there is a lot going on and not surprisingly a lot at stake. The good stuff is unseen. But VW has also stepped into virgin territory in offering a DSG (5 speed dual clutch computer controlled MANUAL) , which even they shorthandedly refer to as auto, auto/manual AND a manual manual, aka 6 speed manual. Naturally they want it seen in the best possible light.
 
Upshot is the 6 speed manual still probably gets better mpg. It would be my choice if I were solely driving the vehicle. Because of the increased power and one gear more, I would say the "real world" mpg can literally be all over the place. But I think IF you are say getting 50 mpg on a 5 speed 2006 on down TDI model, you will probably have no issues getting 50 mpg on the new one and at more power and torque !!! A woo hoo I'd say. Who would know what a noobie to diesel will do. We all that drive diesels (VERY SMALL population, aka less than 2%) know you have to drive it differently from gassers.

It is that time of year again... I pulled my pipe-insulation out from its storage near the spare tire and installed it.
 
Here is some info to remind TDI owners how to get heat a little faster in the cabin.

Purchasing 1997 jetta TDI by Wildwr
Nov 25, 2008 (3:02 am)

I currently have a 1990 Jetta gas and it's time to upgrade. I
 have an opportunity to purchase a 1997 Jetta TDI with 200,000kms, w/new struts & brakes. the car itself is in prestine condition. Looking for good bad and ugly on this car as I've never owned a diesel before. My trips to work and home are less than 20km/day.
Is there anything I should take a closer look at on this car?
Is my short drive to work everyday going to destroy this car?
The price is right at $2000 certified and I forgot to mention it is a family member I'll be purchasing this from so I do know the history of this car.
 
Thanks

Jetta TDI media file options by mojojones
Nov 26, 2008 (11:21 am)

I spoke with a dealer about the media options available with the Jetta but he didn't appear to be too confident in his answers. I'd appreciate any help with:
-- does the standard TDI stereo play WMA files?
-- without upgrading to the navigation system, is there a way to connect a USB drive (thumb or hard drive)? I realize there's an aux-input for mp3 players but I was hoping for a direct USB connection or available adapter.
-- can the MDI connector be used with the standard stereo or only with the nav. system?
 
I would love to look at the back of the stereo to see what connections may be possible but I don't think the dealer would be too keen on me removing one. Thank you for any help!

2009 Jetta TDI oil issue by etracey
Nov 26, 2008 (8:32 pm)

The manual states use only 5W30 VW standard 507 oil. It also states to carry a quart of this oil because it may not be found in North America. I call Castrol and was told that they do make the oil but can only supply to VW dealers. I went to my dealer and found that they did not know about this standard 507 and did not stock it. This is the largest VW dealer in South Florida. They would check with Castrol. Where can I buy any 5W30 VW standard 507 in South Florida? Thanks

The MDI isn't compatible with the standard stereo. VW will have to upgrade to the RCD310 and the RCD510. Those Units are compatible with the MDI. The standard jetta radio plays MP3 but not WMA. The MDI can support USB hard drives and USB thumb drives if they are formatted in FAT32. You might have to retrofit to the RCD310 or the RCD510 if you want the MDI to work.

etracey maybe you should phone order it from a local dealer where they pronounce 'diesel' with a Z sound instead of an SSSSS sound. ok, seriously you can find a dealer who pronounces it with SSSS sound who knows about the right oil too, it really doesnt correlate with pronounciation!
 
for any parts counter dude, one call to vw tech center would give the part #, in case their google-favnerhugen search skills are not up to the task.

Diesel Additive necessary with ULSD for 2009 TDI? by c280
Nov 30, 2008 (2:16 pm)

I'm definitely not an expert when it comes to diesel cars and it's maintenance. The '09 Jetta TDI is my first diesel car. Just wondering if the diesel additive like Powerservice is really necessary for these newer diesels taking into consideration that the new cars use ULSD?

The answer is officially no and unofficially....yes: to firmly no and/or yes for either!!?? (I used to be indecisive, but now, I am not so sure!? VW recommends NO additives; but oxymoronically when pressed or you further research the subject, unofficially endorses one particular one. (No, I don't use THAT one. It is sold usually at the VW dealer's.)
 
So because the 09 TDI meets the new so called higher 50 state legal requirements (the 03 on back TDI's WERE 50 state legal ) you might want to go onto some web sites as the actual product is different for different applications:
 
1. AVLube.com web site link title
 
2. Power Service link title
 
3. Primrose link title
 
4. lastly www.tdiclub.com to form your own strategy and opinions.
 
Anymore it "DEPENDS"
 
Incidently further back than the 03 MY the VW TDI engines have been designed for ULSD !!! I just can't quote the EXACT year it actually started.
 
I personally have been using a Primrose product (since new to 111,000 miles), 03 TDI, mainly for peace of mind about the expensive fuel pump (lubrication), and for the emusification of H20 issue. It does boost the cetane rating. It is the so called C or 3000 to 1 concentrate.
