I had two of those. As legendary as they were, they had their shortcomings.
 
Modern diesel cars that I've driven are light years ahead of an old 300D or SD in performance, noise level, comfort and economy----but I'm not so sure they are ahead of the old tanks in build quality and reliability.
 
There is a certain allure to rugged simplicity.

I think I mentioned this before. I read an article in a business magazine about a company in the Midwest. They would only buy used MB 300 diesel cars for their sales staff. They looked for ones that were close to 100k miles in good condition. Usually bought for a song. They had their own mechanic and they ran them to 300k+ miles.

Yep, they're great. But being German cars, if some big thing went wrong (cracked cylinder head, bad automatic transmission) you probably have to throw the car away, as the repair is worth more than the automobile.
 
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.

If you own Japanese car in Japan, the engines planned "obsolescence is at 4 year or 50,000 miles (new engine required) There is/was a HUGE US (after) market for those so called "obsolete" engines. If you want to put a recognizable graphic current face on them; RICERS. Most did not buy BRAND new crate engines for their modifications.
 
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 !!!!

Yeah diesels seem to perform best at that RPM range 3000--4000.

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

That's a nasty price to have to pay, but some models of Audi will cost $1000 for headlights as well. Besides the guy in that article who was complaining had 65,000 miles on his car and wants Toyota to buy him headlights?

And I was howling like a scalded dog when my (HB5 9007) low beam blew out. Got a two pack 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.

When driving I use to keep my 335d coupe within the max torque range (1750-2250 rpm) far away from its max rpm (>4000). In 6th gear that converts into:
 
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

Indeed ! Also the BMW 335D is one of my dream cars !!
 
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.
