Golf IV / Jetta IV :: Engine Temperature Rises When Heat Is Turned Off / Hard Pull
I have a 1.8T with 152kmiles
Recently, both the coolant reservoir 'Y' connector and the driver side coolant flange cracked and I was shooting G12 all over the engine. I've replaced both of the parts and the coolant temp sensor with a "green top". Reservoir was refilled with the proper ratio of G12 to distilled water, ran for a bit and topped off accordingly.
This morning I started my drive to work and the engine temp was at 0 for a minute or so and started to climb slowly to 190. It stayed at 190 until I took the exit to the highway and the temp slowly started to rise while I was at 60mph. I immediately turned around and went back home with the heat cranked to high. With the heat on, the engine temp would slowly go down but then rise again if I, A. turned the heat off or B. made a hard pull up to ~55+mph.
I popped the hood and the coolant was not boiling and I couldn't see/smell/hear any leak. could this be the thermostat or is this a water pump issue? I plan on taking the thermostat off and checking the pump empellars for any shards. I'm not sure but I do believe the water pump was replaced by my parents while I was on deployment.
Golf IV / Jetta IV :: Hard Time Starting / Engine Turned Over But Wouldn't Fire
2003 1.8t gti ... Today when I got in my car...it fired up perfectly normal but when I got in it from leaving school it took 5min to fire up. The engine turned over but wouldn't fire all the time as if the spark plugs were bad. So I bought new NGK spark plugs and had the same issue just a little bit ago.
I know the obvious thing would be to change the ignition coils but they're out of stock everywhere so I have to have them shipped. My question is is the ignition coils the problem? They looked a bit worn but nothing serious.
Golf IV / Jetta IV :: 2004 - Leaking Gas After Filling
2004 Jetta 2.0, just purchased the car and my first VW. Filled up for the first time last week after purchasing and when it was full (gas pumped kicked off) a small amount of gas spilled out from under the car. Best I can tell from above the passenger rear wheel area. Under a gallon but just enough to make a small puddle. Nothing came out of fill cap or near the nozzle. 2nd fill up tonight and it did it again. I was careful to fill it slowly and went to a different gas station.

My Jetta is leaking gas like a sieve when the fuel pump starts. Its pretty obvious where its coming from. What this part is called or if there is more to it than just replacing it. Its coming from the round looking part on the fuel rail. Let me know what you think.

Golf IV / Jetta IV :: Fan Automatically Quits When AC Is Turned On
I have been trying to tackle my AC problems for quite some time now...I noticed my AC was not working properly a little while back, so I ran the diagnostics on climatronic. It came back saying AC high pressure switch. I replaced that -- still nothing. I continued to run more diagnostics. My fans run when the car heats up, so its not overheating, but when I turn on the AC, no fans come on automatically. I jumpered the fans directly off the battery and they both work on both speeds. When I hook it up to the thermo switch plug, it only works on low speed. I replaced the FCM, which had a lot of corrosion on it -- I Even had to run repair wire for 2 of the pin ports. I Jumpered the compressor too, and it seems to have kicked on as well. Even if the compressor were bad, wouldn't the fans still try to run when AC was on.

I have a 2002 Golf GLS. About a week ago I was driving around like a raped ape and spilled some soda down the gear shifter. I cleaned it up and didn't think anything of it. Recently, now that it's been getting colder out I found that my car doesn't want to shift out of park when I turn it on. No worries, just did the ("Step on the brake pedal five times,
hold the brake pedal down, start the car, shut off the car, turn the key a quarter turn, move the shift lever between neutral & drive, start the car and then you can move it into drive.") and shifted into gear fine.

Golf IV / Jetta IV :: CEL Turned On With Code P1116
I've recently had some problems with my 2000 Jetta VR6, so in the past couple months I've replaced the alternator and the coolant flange/thermostat housing. I bring this up because right after i finished fixing the coolant leak, i got a check engine light. I had screwed up, though, and switched 2 of the spark plugs when i was putting things back together and I assumed that was what caused the CEL to turn on. I put the spark plugs back in the right place after a minute or 2 of confusion... but the light has stayed on for about the past month. Got it to turn off by unplugging the battery for a bit, but it came back on after a couple minutes at idle. Took it to Autozone... and the P1116 code that pops up says "O2 sensor heater circuit open bank1 sensor 1." I feel like it was probably something that I have done to cause this problem, not actually just a part I need to replace based on the timing of the CEL.

So I go to start up the old girl the other day and she turned right over, ran for about 2 seconds, and shut down. I tried to start it again with the same result. When I turn the ignition forward, before starting it, this image with a car and a key below it starts flashing on the gauge and the odometer starts flashing "service". I tried using a different key with the same results, what this might be?
View 5 RepliesGolf IV / Jetta IV :: 2001 - No Spark When Engine Turned Over
2001 Jetta GL, 2.0L, 170k miles.... It won't start and it's not likely the fuel pump. After the car has sat for a while, I hear the fuel pump spin up when I open the door. It turns over just fine. I pulled a spark plug, attached it back to the wire, held it close to the head, and when the engine turned over, no spark. Is that still a valid test for spark? I haven't had to diagnose a spark issue for so many years, I don't know whether that has changed.

This morning my cars battery was dead and when I tried to pop the clutch to start it it went into gear but nothing turned on. When jump starting the car it turned on I drove it for a little while and was idling when it shut back off (battery was dead again). I came back to the car in a couple minutes, tried to start it and it started right up. I'm not sure what to think of this.

I was driving around and I got a low oil light flashing and it turned off straight away.
So I checked my oil. When I first removed the dipstick it shows full, wiped it clean and put it back and it showed empty.
I put have a bottle (small one can't remember size) of oil in. I drove around parked waited a bit, and it does this same thing.
Golf IV / Jetta IV :: 1999 VR6 Shaking Quite A Bit On Startup And When Turned Off
So my VR6 shakes quite a bit on startup and when I turn it off. I figured it was the dogbone mount. I did the clutch trick, jacked up the front end and engaged the transmission. Of course the engine shook a lot, in a forward to back motion, signalling the dogbone was bad. Shifts into and out of 1st and 2nd were pretty rough and i could feel it in both the driver and passenger seats during idle.
Well I just installed the ECS dogbone and while I can't really feel it much in the seats anymore, it still shakes quite a bit once the transmission is engaged. Low end shifts really haven't gotten much better either.
So I am thinking its either one of the other mounts, or the polyurethane bushing needs to be worked in. I am leading toward the former.

I have 2002 2.0 Jetta that I totaled. I found a 2000 2.0 Jetta that had no engine or tran. I swapped the entire wiring harness with the engine and trans from 2002 into 2000. I even swapped the doors. The cluster, steering column and all. I am still in the process of getting a few parts to finish it up. At this point, the only thing not hooked up is the headlights and the radiator. I hooked up a battery and tried to get it to turn over today. I turned the key to the on position and the cluster did not do anything. The engine turned over very slowly in the start position.

View 2 RepliesGolf IV / Jetta IV :: Windshield Wipers Turned On And Won't Stop When Car Started
As soon as I start the car the windshield wipers start on their own and wont stop. I diagnosed the relay as my fualt and I was partly correct. I put the new relay and it worked. However I still had the rear wiper motor disconnected. Once I plugged rear motor back in, the front windshield wipers started going on their own and won't stop again. So, what should be next? Motor diagnoses? I can't see any visual water damage in the motor when the cover is off.
