>i have a 86 jetta with a GX engine and i was wondering if a external fuel pump assembly off a 90 jetta will fit on it because they look different. the newer one is smaller and more compact. thank you for any help.
The external fuel pump assembly from a 90's Jetta will not work on your car. VW switched fuel injection systems from the Continuous Injection System (CIS) which is on your car - to a fully electronic Digifont system. Here's a brief history of the different fuel injection systems used in VWs: http://www.autotech.com/catalog/fuelinj.htm The external fuel pumps are very different in the sense that the CIS fuel system must be pressurized to around 70-80 p.s.i., while the Digifant system on the 1988 through 1992 models is pressurized somewhere in the neighborhood of 40-50 p.s.i.
Bottom line: You need to find a fuel injection assembly from a 1985 through 1987 model year VW.

Since your car is out of warranty, I would steer clear of the dealership and look for a mechanic that specializes in either VWs or European cars. You can get equal service from the private mechanic as the dealership and save yourself some $$$$ on the labor charges...

Nov 02, 2005 (1:40 pm)
I have this exact same problem. I have an '05 Jetta (not the newest generation) w/about 13K miles. I brought the car in to the dealer complaining about the auto transmission and how it rolls when cold. I was also told that the rolling has to do with the emissions control situation. I asked what happens when I roll back into someone and there is damage to that car, who is going to pay for that one and I was told to use my e-brake. I then indicated that I purchased an automatic to avoid having to drive stick anymore. I live in the bay area and there are hills everywhere, plus it doesn't have to be even a steep incline or decline for the car to roll almost more than my manual '92 VW evere did. Has anyone been successful in getting this resolved?

I have a 1997 jetta gt and just replaced an o2 sensor and i was told that i had to drive a certain amount of miles before the computer in the car would reset and the check engine light would go off. does anyone know how far i have to drive? I was told anywhere from 50 miles too 200

The errorcode should be manually RESET using computer. Most mechanics will reset the codes after replacing parts. Do not expect it to go out by itself....that is a hit/miss propasition.
Alternately, many auto-parts places will reset the codes for free.
If, after resetting, the CEL comes back on in a few days, then the problem is NOT fixed.
Personally, I use VAG-COM to diagnose and reset the codes in my VWs.

thank you for the further advice! I've had my car back for about 2 weeks now and it seems to be running OK. Sometimes, when it is cold out and I start it, there is a rattling in the engine that lasts about 2 seconds and then the engine runs fine. Being that I really don't know much about my car (though this website and the people who post here have been tremendously helpful), I'm hoping you can take a look at the work that was done and let me know what you think..Is this just a quick fix to the problem that is still existing in my car?? If anything, maybe this will help anyone else who is having similar problems with their vehicle...
Sept. 19th: Car towed, EPC Light/Check engine light came on --car would not go over 25-30mph
Diagnosis: VAS 5052 diagnos acceleration position code pinpoint tests replaced accelerator pedal sensor, retest clear code set readiness road test operating in spec.
Oct. 10th: Car towed, EPC/Check engine light on again, car idling between 4-6,000rpm
**Code P1639 pinpoint tests replaced control unit, code unit & key, clear code set readiness
**Reprogram instrument cluster (Recall)
**Car still idled high after control unit replaced. Replaced accelerator pedal sensor (again!)
**Replaced throttle valve, still idled high, reinstalled old throttle valve, replaced throttle pedal, retest, operating in specs SPW throttle pedal
Oct.17th: Car towed, cold start car idles at high rpms again
**Battery perform charging and starting system check, check vehicle for abnormal current draws, remove & replace battery, reset electronics
**Found that the alarm goes of when starting vehicle, traced problem to drivers door latch
Replaced door latch
That's all the paperwork really tells me..should I be worried? It is now 11/3...should I be expecting this problem to occur again? And one final question...despite all this engine trouble, I found that I had a slow leak in my passenger side tire. I had it replaced because a bulge formed in the outer tire. The tire was replaced and balance tires were rotated. Now when I drive, I can hear a swoosh- swoosh, swoosh-swoosh from the driver's side front tire--like it's rubbing on something. 1) do I need to get my tires balanced? 2) does this tire need to be replaced? 3) is the car safe to drive?
thank you, thank you, thank you...in advance!

The "rattling in the engine that lasts about 2 seconds and then the engine runs fine" is most likely just a "leaking" hydrolic lifter. (There are 2 lifters per cylinder...thus you have 8 lifters in a 4-cylinder engine )
The oil-pressure from the oil-pump is used to take the "slack" out of the valvetrain. (thus the name hydrolic lifters) After being parked for awhile, somtimes a lifter may "leak" the pressure out. Thus, when first started, it takes a few seconds to "pump back up" and you hear a tapping/rattling sound until the slack is taken out as the oil-pressure builds back up in the leaky lifter.
This is usually not a big deal and not somthing to concern yourself about. Somtimes, the hydrolic lifters can be quieted down by using some kind of oil-additive like "STP oil treatment" . STP is VERY thick and helps keep the oil in the lifters while the engine is shut down. STP also contains extra detergents that may clean the crud out the lifter thus making it work better.
I have had some cars that, after treating with "STP oil treatment" for several thousand miles... the lifter noise is all but gone even when NOT using STP on the next oil-change.
As for your tires, have them all inspected/balanced Many people have tires balanced once a year because as they wear, the balance changes.
How many miles are on your 2000 Jetta?

Thanks, pbeebles! My car is due for an oil change, so I will take care of this & the tire balancing this weekend. Since I just replaced a tire and had them rotated, maybe the balance is just what it needs. My car has about 41,600 miles..When I took the car in to have the tire replaced, I asked if I needed to get 2 tires instead of just one--but he said that the tires were still in good shape and only 1 new tires was necessary. I also noticed a little bit of vibration in the steering column, so I think your diagnosis is right on!

Nov 03, 2005 (5:57 pm)
hey, i have a 2000 Jetta VR6 GLX and also had the same problem with the EPC light and the car being stuck in park. i was on vacation and out to dinner. probably just as bad as being stuck on new years. the dealer charged me to replace the brake switch though. is it true that you had it fixed for free due to a recall? if so, do you know what the actual recall was (number or code) so that i can look it up.
also, when you check engine light and emissions workshop light came on, was your car sputtering when idling at a light or stop sign (possibly with flickering lights)? that is happening to my car and am curious as to what you did to fix whatever was causing those check engine lights to come on. did the O2 sensor work?
i would really appreciate the help.

Does anyone know if there is a problem with the engine light on the 04 model jetta? Mine just came on, how frustrating as it's practically new with only 20,000 miles on it! I'm suppose to be leaving on a road trip in the morning...
