With 66K miles on it, that Jetta probably didn't spend much time in the shop for repairs. Get a Carfax report and ask for the maintenance records. Compare the maintenance records with the VW recommended maintenance schedule for that model. Edmunds used car guide can provide a reasonable price for your location. You have experience with diesels, so you can judge the car's running condition during the test drive. If you have doubts, have an independent mechanic check it out.
 
If the car's history and price are good, go for it.
 
We've had one minor electrical problem with our 2004 Passat TDI in 33K miles, and absolutely no problems with our 2006 Jetta TDI in 11K miles.

I have an 04 PD TDI Jetta and really love the car. If I were going to buy a used one I would be carefull to check that the correct motor oil had been used in it. The Pump Deuse Injectors develop 30,000 psi of fuel pressure and are actuated by the camshaft. This creates a lot of sheer stress on the oil which is why there have been quite a few posts with worn camshafts for people that didn't use the right oil (the 04's require VW Spec 505.01, 506.01, or 507). I would also ask if the EGR cooler recall had been done (the EGR coolers had a very high failure rate and 4 or 5 months ago VW came out with a new redesigned cooler that should not have that problem). If you buy it, be sure to do the timing belt (and everything that turns along with it: tensioner, idler pulleys, water pump) in another 34K miles. Good luck

I just bought a 2001 Jetta 1.9 TDI. The problem I have is after I drive the car for about 15 - 20 minutes it loses power to the point where it won't hardly go. I have to let off the accelerator pedal, let it idle for a while, and then it seems to clear up. After that it works fine for another few minutes before acting up again. Does anyone have any idea what is causing this? This is my first diesel and I have no idea what to look for. Any help would be greatly appreciated.

I cannot relate your symptoms to anything specefic... My initial thought is gelled fuel. (which then thaws after being warmed in the fuel-filter for a bit.)
 
What is the ambient tempartures where you are and have you been adding antigell to the fuel at every fillup?
 
How many miles ago did you replace the fuel filter?

If the intake manifold has not been cleaned this is a very common problem with these vehicles that will cause the problem that you describe.

It's been in the upper 20's during the day and drops down to the teens at night.
 
I just bought the car and the guy I got it from said he changed the fuel filter not too long ago. Unsure of actually time.
 
This is my first diesel and I wasn't aware of any antigell aditive. I assume you'd get that ay any auto parts store, right?
 
Thanks for your reply.

It's almost time for the 80k maintenance. Is this something they would do as routine maintenance. By the way, I was shocked at what the 80k maint was going to cost. Almost $1000.

Since my TDI was new, I always add about 6oz of Power Service additive at every fillup. (Some folks chose to add it when they get home from filling up.)
 
Summer ==> Diesel Kleen +Cetane Boost
Winter ==> Diesel Fuel Supplement
 
POWERSERVICE products are available at WallMart.
 
Unlike some of the "snake oils" that are sold as "additives" for gasoline.... Diesel fuel in North America is pretty crappy and needs some help. Adding a few Cetane numbers can improve MPG and reduce engine noise. (Obviously antiJell is a must in the winter)
 
Also, using a diesel fuel additive also lubricates the VERY expensive fuelpump and keeps the injectors clean.

Thanks BP for some valuable information.
 
I will certainly go out and get some today.
 
If you know of any other resources, on the web, that might be helpful please let know.
 
Thanks again.

I agree with bpeebles...
 
It could be the gelling in the low temperatures..
or the fuel filter...with gelled waxy stuff inside..
or intake manifold...though it must be really dirty to cause any symptoms as severe as yours.
 
You should go to the link for the site for tdi owners, above....see link 1 .
