Replying to: dungeonx (Oct 29, 2009 12:56 pm) If you are certain the fuel-pressure in the rail is within spec... then the problem is electrical power to the injectors.   I assime you checked all the fuses and fusable-links. It is the engine-computer that controls injection signals to the injectors.   Let me say that another way... the engine-computer sends the "signals" to the injectors but the bulk of the POWER comes from another source. Typically, +12 is CONSTANTLY fed to the injectors and the engine-computer momentarilly shorts the other side to GROUND to cause an injection-pulse.   Check for +12 on all injectors.

Replying to: edsue (Oct 31, 2009 2:55 pm) Sure sounds as if computer is detecting unexpected signal from engine-temp sensor.   Some of the engine-temp sensors up till about 2001 were found to fail prematurly. The replacement component is different design (read "more reliable")   On the 2.0L engine, this sensor is trivial to replace. I replaced one on my daughters car in the dark while she held the flashlight. (Dont forget to also replace the O-ring at same time.)   Cost for temp-ensor and O-ring was about $15 when I had to get one.
#6241 of 6270 computer is locked by piglets2 Nov 02, 2009 (9:01 am)
well today in my auto course we hooked it up to a gesisus scantool and it asked us to verify a code that i did not have so i guess there is no existing problem with the computer but i do have to take it to vw, and pay 110$ to get them to hook their HUB to it and print me off the faults.

Replying to: dungeonx (Oct 28, 2009 8:51 am) We were getting spark as well with damaged ignition coil. Apparently not enough voltage or not synchronized enough for German engineering. Change it out, see if it works. If so then you have found your problem. If not get a refund when you take it back. Just don't screw it down in place and then it is not considered installed.   Or get one from a junk yard to try. If it works get a new one.

I am having troble with the driver seat. The adjusment for front to back movement will not catch except at the most forward or posterior position. How do I repair it? Does it require me taking the seat totally out or can I just remove the seat cushion to get to the mechanical parts?

Replying to: golfergreen (Nov 20, 2009 5:44 am) You have to take the seat out - but - do not unplug the wires/cables as you may trigger the deployment of air bags. Do not remove seat cushions! In order to remove the seat, you have to get a special "star" socket (available at PepBoys or AutoTrack) and remove 4 bolts - two in front and two in rear - that hold seat rails. Then you flip the seat backwards (with rails attached) and see what's causing your problem.

Replying to: golfergreen (Nov 20, 2009 5:44 am) Sorry, my advice pertains to 09 VW Jetta... just noticed that you have 2002 - not sure, if my advice is applicable to your model year. I do not want to disseminate an incorrect information.
#6246 of 6270 Re: 02 jetta battery drain [heather26] by summermirage Nov 20, 2009 (9:46 am)
Replying to: heather26 (Oct 20, 2009 6:05 pm) I have the same car. VW Jetta, 2002, the low-end version. It too now suffers this problem. I took the car to a mechanic who looked for a parasitic battery draw on the car after the key was taken out and he saw nothing drawing power. But, yet have a week of sitting without use, the battery tends to be drained and can't turn over the engine. Battery is only 1 year old. Anyone have any ideas ?

Replying to: golfergreen (Nov 20, 2009 5:44 am) Golfergreen,   I have had the same problem with my '00 Jetta. There is a metal pin that slides in and out of a sleeve. That's the adjustment. Pin out the seat will slide. When the seat is adjusted, the pin goes into a hole and your seat is locked in. Easiest way to fix this is to clean out the pin/sleeve assembly. A lot of dirt down there and it gets into the workings and causes the pin to stick. It does work itself loose. That's why it does go back into position all the way forward and back. You can snap up on the adjust handle, but that will only tear up stuff. Try cleaning the assy with some spray cleaner. I used dry lub after the pin was loose.   Tracy
