What can you tell me about VW's TDI engines with Pumpe Duse?

Question

Like: what year TDI's was it on, would you reccomend I buy one, or previous or current TDI instead? And, where can you get the special REQUIRED oil (505.01) besides a VW dealer?

My boyfriend has a 2004 Jetta TDI (w/pumpe duse), I want to buy a Golf TDI & he thinks I should get one without PD because we can not find the oil it requires (but can find the oil for other TDI's without PD) at local parts stores.

TDI's get up to 50 mpg - yes, there is a reason I want one!

Answer 1

'04 '05 & '06 have PD motors.
Don't sell your current TDI, Google ELF Excellium or TDI parts dot com. I buy the oil and filter from them by the gallon and change the oil with a PELA 6000 oil extractor. It is a piece of cake to change the oil and filter.
TDI club dot com is probably the best resource for all things TDI.
If you can get a new TDI, buy it. The TDIs in the D.C. area are pretty much all gone. I checked Ebay yesterday and the '05 passat wagon that I bought for 25K wit 7 miles on it just sold for 31K with 30K miles on it.
From what I was told there are no '07 TDIs, something about the regulations for ultra low sulfer diesel that is mandatory next year. TDIs will be available in fall of '07 ('08 model year)
I've got 20K on mine and have had no problems. The PDs are a slightly larger motor than the previous A4 motors. (2.0L, A4 is 1.9L) The 2.0 has 134HP and 247 LB/FT at 1800 RPM of torque.

Pumpe Duse Tdi

Answer 3

For history sake Pumpe Duse is a version of the VW TDi engine which was supplied in global VW vehicles in 19.L and 2.0L versions. Older TDi VW diesels employed the external, mechanical/electronic VP pump with metal injector lines and mechanical injectors to achieve the pressures necessary for diesel operations. Where this worked, it was neither fuel efficient nor environmentally friendly.

The pumpe duse was devised to settle both issues. It contains a mechanical/Electrical pump nozzles for each cylinder, operated by the camshaft within the cylinder head. The low pressure fuel pump is located on the back of the cylinder head and operated by the cam shaft. Injection is controlled via a Diesel Fuel Injection Electronic Management Controller. Not only is this design very efficient in its use of fuel , it also has vastly lowered emissions output (basically a smokeless diesel which has the acceleration of a gasoline engine, but with much greater efficiency and a far greater longevity). The engine is technically advanced, but with no more sophistication than any other modern turbocharged, inter-cooled, 4 cylinder engine.

The Pumpe Duse (PD) version of the TDi has since been replaced by the common rail version (2009) which improves on the PD system increasing engine efficiency and power while maintaining the small foot print and consumption of the 2.0l engine.
Are these diesels the answer to much higher durability and fuel efficiency for modern vehicles in the US? Since Other manufacturers are now turning to the same solution for the most recent vehicles, and since the modern truck market is mostly oriented on the turbo diesel, its obvious that this technology is bound to be around for awhile.

Answer 4

no, it hasn't. They stopped producing it for now so they could meet the new emission standards in the US. They should be back out the end of 2007 as an 2008 model There is one VW that has a TDI in the US for 2007 and that is the V10 Toureg.

I'm pretty sure that VW removed it from new US-spec vehicles due to the EPA's changes in diesel emissions and low-sulphur diesel fuel. (California's emission requirements are even more stringent than the federal limits.) I believe that VW is working to certify a CDI (common rail diesel injection) engine, like Mercedes-Benz and a few other European auto companies are developing. (A CDI engine uses very high pressure injectors, producing more power, lower emissions and sound levels. They also have additional emission components in the exhaust system. M-B is developing, and VW may be licensing, the so-called Bluetec urea-based emission system to clean up diesel soot particulates.)

Answer 6

Honestly, I don't know what "pumpe dues" is . . . but I have an '03 Jetta TDI wagon w. 117,000 miles on it, zero repairs, loads of torque, every luxury option (leather, sunroof, full power, etc.), hauls like a station wagon -- because it is one -- and Averages 48 mpg (5-speed). As for oil, I take it to a local VW garage -- not the dealer -- for oil changes (synthetic oil) about every 7,500 miles. Cost about $60., but the changes are about half as often as most people change oil in gas engines, so it balances out. Dealer recommended every 5,000 miles; owner's manuals says every 10,000 -- so I've compromised. Best car I've ever owned in 42 years of driving and 2 million miles under my belt. Best wishes on your decision.

Answer 7

is there a reason you want the tdi, the gti's are great and run on regular octane fuel.
