Jetta TDI help by hickey31

I have a 1999 VW Jetta TDI that is sick. It will only rev up to about 2000 - 2100 RPM.
When it reaches this rpm the black smoke rolls out of it (mosquito killer).
Anyone have any suggestions for this car, it only has 248,000 mi.
Any help would be appreciated.
 
Thanks,
Hickey

Doe's anyone know the real reason why the 2008 Jetta TDI has been moved back to come out in October instead of March.

I read in passing it was technical issue found in durability tests and planned corrective actions. As I recall, the VW article (press release) I read was not any more specific than that. They took this action as part of VW's constant improvement program.
 
VW Jetta TDI delayed until summer of ‘08

If you were eagerly awaiting the arrival of the Volkswagen Jetta TDI, you may have to wait a little longer. In a memo sent to dealers this week, executive vice president Adrian Hallmark told dealerships that the Jetta TDI sedan and wagon would not be introduced in April.
 
The 50-state diesel by Volkswagen has been delayed from spring to late summer of 2008. Reason for the delay? Hallmark said that the delay is due to “a technical issue that was found during the later stages of durability testing.”
 
The Volkswagen Jetta Clean Diesel TDI will be powered by a 2.0 liter 4-cylinder diesel engine that produces 140 horsepower with 235 lb-ft of torque. Volkswagen is saying that the new engine’s fuel economy and NVH will be significantly improved over the former 1.9-liter diesel engine.

2.0 TDi by alltorque

In Europe there has been a problem, (in 2006 ?), with the twin-mass flywheel supplied by one of the two possible suppliers. Worst-case scenario was, apparently, an engine fire but the problem is said to have given plenty of warning of impending doom. However, one would expect that to have been solved and not be the cause of the USA launch delay. Odd.
 
We've had the 2.0 TDi 140bhp motor here since late 2004, so it's hardly new. There are still folk who prefer the 1.9TDi 130bhp unit, though................but there again, everyone loves something.

I was told by a rep from local VW dealer that there was a fire at an assembly plant, although I also hear it was a fire involving a Jetta TDI during durability testing. Who knows?

Actually, the 2.0 TDI comes in several 'flavors' and one of them has twin turbochargers and is rated:
147 kW (200hp) 4400 rpm, 400 Nm 2500 to 3000
   
The "applications" for that engine is "VW Golf, VW Touran, VW Jetta"
 
With that kind of torque, it would be a challange to just start off in 1st gear without spinning the tires. Wooo Hoooo!!! Bring it on!
 
Here is the ref. for the specs. ==> http://en.wikipedia.org/wiki/List_of_Volkswagen_engines#140-200hp_2.0_TDI

That sure sounds as if the turbocharger is not doing its thing. (not enough air for the injected fuel.)
 
Check for;
*)clogged intake manifold.
*)N75 valve
*)turbocaharger vanes sticking. [VNT (Variable Nozzle Turbocharger) vanes]

The Wikipedia listing is not totally accurate. I cannot find anywhere that the, supposed, 200bhp version of the 2.0 TDi is used in a VW-Group car - at least here in UK. Is this a factory engine or a modded one ? Also, it states that the 1.9TDi is now discontinued when it's not. It is still available in VW-Group cars in 105, 115, 130 and 160bhp versions ............... and the latter two don't even appear in the Wikipedia listing.
 
In short, it is a good listing but should not be taken as definitive.

And I wouldn't hold my breath waiting on that hot-rod diesel to be available here in the states either. Historically, they always pitch us their left-overs anyway....which might explain less enthusiasm for diesels here....viscous circle.
