Replying to: gagrice (Dec 18, 2008 8:32 am) Passenger car diesels don't like very high revs all the day long. These are not Peterbilt trucks with massive engine blocks. Many an old diesel goes down in the dirt because of that.

Replying to: Mr_Shiftright (Dec 18, 2008 8:36 am) Indeed that is true !!! But really: So What? My current 03 (now old) Jetta TDI (Germ engine, US, Canadian, Mexico, Argentina and assembled in Mexico) can literally run all day and all night at (app) LESS than 2,900 RPMS  app 100 mph, and clock 48 mpg, ( rounding down 585 miles/12.1 gals). Oil consumption is 1/4 to 1/2 quart per 20,000 miles (or so I have heard  ) I would also agree with you that I am a tad frustrated they still build IN notable and CONSISTENT FLAWS !!!!

It is more than obvious that diesels (US market) have to fight an "uphill" battle, (diesel car passenger vehicle fleet at less than 1%.) Contrast that with Europe; where the DC PVF is greater than 50% with yearly sales more like 70% diesel. Of course the HUGE complexity of say this...Roadshow: Cost to replace on-and-off Prius headlights can run $950 — or nothing By Gary Richards Mercury News link title is hushed/downplayed, etc., !!!

Replying to: Mr_Shiftright (Dec 18, 2008 9:20 am) the local WallyMart for 8 (?) bux, aka, 4 bux each. I just replace THE *** one and the one not replaced is soldiering on just fine. However in all fairness, The Prius lamp issue IS a hit to Toyota, as I have a 15 year old SUV that STILL have the original halogen lamps (9005/9006- HB3, if I am not mistaken) !   I still make it a habit for any vehicle (diesel or otherwise) to talk to the mechanics familiar with its maintenance and repair side. Seems being the "guinea pig" can be an EXPENSIVE proposition. |

Replying to: Mr_Shiftright (Dec 18, 2008 8:56 am) 1750 rpm = 68 mph 2000 rpm = 78 mph 2250 rpm = 87 mph (If I fancied revving from there it would go to: 2500 rpm = 97 mph 3000 rpm = 117 mph 4000 rpm = 155.34 mph But then I would have a full wolf pack with all lights and dragnets behind me to take my license out. Better not to try.) Yesterday I came back home after driving with my wife 1,000 miles to and fro. In the end, highway average speed was 73 mph as a result to try cruising at 86 mph (2,200 rpm), with occasional peaks up to 100 mph to rock the engine. All in cold wether, ranging from -3ºC to 6ºC. Averaged consume (tank filled twice) was 33.5 miles per gallon. Regards, Jose |

Replying to: jlbl (Dec 18, 2008 11:42 am) The US market version Jetta TDI got one less gear (5 speed manual vs 6 speed manual) so the TDI engine in the 5 speed SCREAMED as compared to purred with a 6 speed.  I understand the 2009 TDI got corrected and now has the 6 speed manual (6 spd DSG also). Indeed I do not expect most non diesel owners to really understand the max torque concept: yours 1750-2250 rpms, VW being 1750 rpms. 2500 or so RPMS seems to be the SWEET SPOT for longevity for the TURBO. RPMS much over that is sort of lost.
