#150 of 4777 97 JETTA TDI *No climbing power*!!!
Apr 08, 2005 (2:01 pm)
My girlfriend has a 1997 TDI turbo/fuel injected Volkswagen Jetta. A few months ago it started becoming quite sluggish, especially noticable going up any type of grade. It is usually a very peppy car and has just over 200,000 km which from what I have heard is not much for these engines. It starts easily and idles great. My mechanic buddy had me change the air filter, and add a fuel cleaner into the tank on fills but didn't do anything. We then changed the fuel filter and it was considerably better (not 100% the way it was) but very noticable difference. After a couple of weeks the car has become sluggish again. He thought it may have something to do with fuel pressure or the pump itself.

I also have a 2004 Jetta TDI and I recently drove 1300 miles to florida and parked in a freshly painted gray garage and saw no signs of anything on the floor except A/C condensation.
This is my second TDI and I never seen black particles left behind,I hope this helps

Lets hope it is NOT the fuel pump. (A diesel fuel pump is VERY expensive even a rebuilt one may be near $800)
There are several things I would check
*) Snowscreen plugged up (easy to clean)
*) intake plenum plugged up (somwhat harder to clean)
*) bad MAF (about $100 - $200 part)
*) VNT vanes carboned up (may be able to free them up by wiggling the lever)
VNT = Varible Nozzle Trubocharger
#154 of 4777 VW JETTA TDI-New Engine?
Apr 10, 2005 (2:17 pm)
I bought a 2002 JETTA TDI Feb of 2004 with 28,000. It now has 74,000 miles. I was driving on the freeway when I heard an unusually loud knocking sound coming from the engine. It also acted as if it lost power. I immediately pulled off the road and had it towed to the dealership. The service shop is telling me I need a new engine because of a lack of compression. I guess my question is do Jetta tdi's engines only last 75,000 miles?

The TDI engine has been known to go at least 300,000 miles. Diesel engines in general should last TWICE as long as a gasser.
Your engine obviously had some kind of unusual failure. I wonder if the timing belt was not replaced at the proper intervals? If the timing belt skipps a tooth, the valves can contact the pistons making for an instatnt boat-anchor.
Another possibility is that the proper synthetic oil was not used in the engine.
Do you have any other details about what the problem is? "Lack of compression" does not automaticly mean you need a new engine. A good mechanic can use a remote-camera and snake it into the engine to 'look around" and make a more detailed diagnosis.

Synthetic oil was used at the recommended intervals and the timing belt is not recommended to be changed until 80,000 miles, however, the mechanic has ruled that out. Volkswagon is requiring the dealer to disassemble the engine for diagnostic purposes. The mechanic said that he was 90% sure that a new engine is needed, but he had not made a determination as to what exactly caused the compression loss. It has run problem free up until now. Its a mystery. I am hoping that VW, despite the fact that the engine is 14,000 out of warrantee, will back up their product if this is some sort of manufacturer defect.

Thanks for the suggestions Bruce. I will look into these one by one. I have a diesel mechanic buddy who has helped me when he has time. I am leaning towards something being plugged because of how much better it ran after changing the fuel filter. Yet after a couple of weeks it has become sluggish again, frustrating.
He mentioned having the fuel pressure checked but wasn't sure quite how to do this on the vehicles.
I'll let you know how I make out.
