#1245 of 4777 Re: Should I buy a 2004 Jetta?? [secokenn]
Jan 30, 2007 (10:00 am)
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
#1246 of 4777 Loses power
Feb 01, 2007 (6:07 am)
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.

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 .
#1254 of 4777 Interior Heater
Feb 08, 2007 (6:31 pm)
Does anyone have any good recomendations for a portable interior 12vdc heater, possiably one that operates on 120vac as well. The Jetta just will not warm up for at least 10 min of highway driving inside the car. If I drive around the city good luck getting much heat at all (thats where the heated seats come in)! Now I have a baby in the car and unless I take the car out for a spin first to warm it up the poor baby freezes. The cold weather is unreal this year -40 So much for Global Warming!!!
