Golf IV / Jetta IV :: AC Randomly Stopped Blowing Cold Air
No AC... Its not the fuse box on top of the battery, I recently already changed that. The air coming out is not cold at all, so I checked the pressure, and it was even higher then it was supposed to. After letting some pressure out, still no cold air. What could the issue be? Should I maybe bleed the system?
Also, its a 2001 GLX so I have climatronic....
Golf IV / Jetta IV :: 2000 Randomly Cutting Out
My Mk4 2000 Jetta 2.slow has been acting up, a week ago I went to pick something up from my fathers house and a minute later I cam back to start it to only have the idle strange,it as well the throttle being all sorts of weir till it cut out and I had to push it into the drive way. I has the coil pack tested, and it was measured to be right where it needed to buy. I then bought starting fluid and after spraying it into the air intake it started. I had it running till it cut out and had to redo it again. Then when driving home again after putting more in it stopped, I was able to start it again keep moving for another ten second before having it stop again. I am receiving no check engine lights, alternator is good and as wel as the battery.

I let the car die completely turned it back on and it eventually turned back on .The check engine light was on I then headed home I also noticed while in 4-5 RPM the car would not have that much pressure . Like it wanted to shut off again .. I was doing some research from similar issues like mine . Someone said to replace my EGR Valve and my Speed sensor.

So I have a 2004 jetta GLI (1.8T) with forge splitter valve and short ram intake. I went and got my codes pulled and all 4 cylinders misfiring and random misfires. I replaced both coil packs and spark plugs. check engine light popped up again after about 20 miles and same thing. I just bought the car so I'm not sure how long it has been running with these misfires. I just got the timing belt replaced. I know it could be off a tooth. (Wouldn't a code pop up though for it?) How could I check that. And I also took my MAF sensor off as well and no change. Heard it could be clogged cat, any way to check? I've also cleaned the throttle body. It runs fine when I'm driving, just a rough idle.

I got my jetta over a year ago, and during that time I've accidentally left the lights on a number of times. But just a few days ago it started making a tone when I leave the lights on. Is there some way to turn that feature on and off, or was something wrong that mysteriously healed itself?
View 3 RepliesGolf IV / Jetta IV :: SAI Pump Cutting On Randomly While Driving
I recently replaced my SAI pump rivets with stainless bolts so everything is nice and tight. However, the pump will randomly cut on and run for a few seconds while driving... i notice it usually when I come to a stop, such as at a stop light. I would assume this is because there is an air leak somewhere in the SAI system... sound likely? Maybe purge valve? I haven't yet had it pressure tested in case there is something I can easily to to rule out most potential sources.

I believe this fuse has to do with radio and convenience options? 2004 mk4 GLI 1.8t. A few weeks back, the fused popped. I replaced it, and drove fine for a few more weeks. Shut off randomly, so I put a fuse in, try to start, it cranks like usual, but doesnt start. Tried with several different 20a fuses. It pops all of them the second I crank the car. Obviously there is a short somewhere. Where? Or know where fuse 37 goes?
View 2 RepliesGolf IV / Jetta IV :: 2004 1.8T Randomly Stuttering And Dying
I'm getting used to just expecting a problem with this car every 3 months or so. Anyway, I have a 2004 1.8T GLI which lately has been idling and then stutters and dies. The first time it happened it turned right back over and started driving. So I drove it home and cleaned up the battery terminals and it didn't seem to have a problem since. Now about a month later I was just parked and turned it over.
It was on for about 1 second and then it stuttered and died. I can hear the starter engaging and turning the engine, but it won't turn over. I also checked the battery levels and its showing 12v so I don't think it's electrical? From scanning forums here it seems like the two prime suspects are spark plugs or the fuel pump?
Also checked the fuses and none are burnt. I could see it being the fuel pump because that would explain it randomly stuttering and dying. Also the car is at 149k miles and that is the original pump. Wondering if maybe it being at 1/4 tank isn't working either? Going out to buy a vagcom and see what codes it throws!
Golf IV / Jetta IV :: A/C Is Blowing Hot Air Only
What are the normal things to look for to troubleshoot an A/C system? I do not have much experience with A/C's. I do not hear the compressor kick on, and it is blowing hot air. I know the fans should be on but both of them at the same time as soon as I turn the A/C on? I was thinking it's not the freon because it will lose its cooling over time not all of a sudden not work right?
View 24 RepliesGolf IV / Jetta IV :: 2001 2.0 Dies Randomly While Its Being Driven / At A Stop
So here's whats going on now. My girlfriend has had her car for about 10 months now, and besides the last 3 weeks it has been a perfect car. In these last 3 weeks though her car has been a real pain.
Her car randomly dies while its being driven/at a stop. It doesn't matter how fast she is going or how long she has been at a stop.
It first started 3 weeks ago when i was driving it to the mall with her and the car started to slow down on the freeway, going about 65. I pushed on the accelerator and got no response. After about 5 seconds all power came back and we were off. At no point in time did the power inside or the headlights dim/turn off.
Next time it died it wouldn't get going again. Battery was fine. My first assumption was the fuel pump. Replaced the fuel pump and it ran fine.
A couple days later the car did the exact same thing, except this time the battery was completely shot. Took a look at it and it was almost 8 years old. Went and replaced it.
The following day it died again, this time it was the battery again but since it was a brand new battery we knew it couldn't be the issue. So i went ahead and replaced the alternator. Turned on the car and it ran perfect. While it was running i even disconnected the battery just to make sure the alternator could still power the car, no issues.
A few days went by with everything working perfectly fine, not a single issue that is, until tonight. As my girlfriend was coming to pick me up her car died. She was coming up to a stop light and starting to slow down when her car lost power again. All the lights and radio stayed on but the car died. Battery light came on as well. I walked to her car and told her to try to start it. Fired up right away and ran fine like nothing ever happened. Drove it to my house without another issue.
At this point i'm stumped. The CEL is not coming on, which is a bummer because that would make this much easier. I cleaned off the terminals for the battery and the connecting wires (which weren't dirt or corroded).
Golf IV / Jetta IV :: 2004 GLI Randomly Misfiring After Exiting The Freeway
2004 gli , 1.8t , 136k , 6 speed
The car started misfiring after exiting the freeway, at the light it felt like it was gonna cut off. The brake pedal is stiff like the car is off. When it's idling is when it's most noticeable. It smoothed out after 2nd gear at like 35mph but still not right. The pedal thing has never happened before but I knew the sputtering was the coils, so I had it scanned and sure enough. 5 codes.random misfire.. random misfire all four cylinders.. so I bought 4 and replaced the old ones.. Changed the Sparks as well. No change.. The cel came back on..still idling rough.. What it could be.
Golf IV / Jetta IV :: 2005 - Oil Cooler Randomly Start Leaking?
I've got 149,xxx miles on my Golf TDI. Took it by a local shop for a routine oil change and since then, it's just been puking oil from the oil cooler. I took it back to the shop and the mechanic even pointed that out. Some red flags here; Timing is too shady. This happened literally the day after the oil change. He also told me that he won't use customer-supplied parts for liability reasons. Seems believable enough, but why would this part just choose to go wrong now?
This is my first time at this shop too and I've never really dealt with "bad mechanics" before but something about this isn't sitting right with me, and I'm not sure how to handle my next step properly. So what would cause an engine oil cooler to leak profusely just after an oil change?
Golf IV / Jetta IV :: 2004 - Die Randomly While Driving - Fuel Pump?
04 jetta 1.8t
apr tune 1.6v
neuspeed 4bar fuel pressure regulator
3" turbo back
APR TIP
This is the second time this happened to me. First time was about two weeks ago where i was just driving and the car stalled. Tried to start but it sounded like it just wasn't getting fuel. Brand new battery, terminals are clean) Got it started and it was revving high like a cold start, normal but why after driving for 30 mins? EPC light came on also which was strange along with the CEL, a buddy checked the code and it was for the secondary air injection pump. (I have not had that go off in a while. Code po4011 secondary air injection. Had this issue a while ago with that code when i did a short ram intake. Tuner cleared it so i can pass emissions. ) Now today it died about 2 miles from my house. Same thing but no CEL. EPC light came on and car was revving high, luckily 3 cars behind my buddy was there and he give me a push into the gas station. Once again it wanted to start but i felt like no fuel. waited a few minutes and it started right up again until it almost died in my drive way. Cluster comes on when it dies. ignition is good.
My big question is the stalling part and the EPC light coming on, then the car revving like it is a cold start but not stopping? and i need this car to be working.
Golf IV / Jetta IV :: Randomly When Go To Start Battery Is Dead 2001 AWD Not Starting
I am absolutely stumped and so are two mechanics I've been to. Randomly when I go to start the car the battery is so dead it won't start. Car is an AWD 2001 1.8T Jetta.
Replaced battery and alternator at my regular mechanic, all ground wires look great and couldn't find any shorts. There is a 11 Amp draw from my battery, took it to a shop that specializes in VW/Audi and they hooked it up to Vagcom and it showed absolutely nothing wrong. He left the meter hooked up and pulled every single fuse in the car and there was only like a 0.01 drop, nothing significant. When he went to take my car out of the shop, wouldn't start. So he put a battery pack on it, still wouldn't start. Took off both terminals on the battery, put them back on, put on the battery pack, and car started.
The aftermarket deck in it is just a JVC single din, doesn't seem to have any issues.
Golf IV / Jetta IV :: Revs High Between Shifts And Randomly Doesn't Start
I bought this car and I've changed out the Clutch Position Sensor, the black one on the clutch mount. Started to work and start but now it's doing the same symptoms as before. So here is what is going on.
1. Randomly doesn't start, full power comes on, and fuel system turns on, immobilizer works just fine as far as I can tell (key light turns off)
2. Cruise control doesn't work (which lead me to the CPS)
3. High revs between shift, once I push the clutch to shift it revs up high, I noticed that if I stay under 3k it doesn't do it as much, but if I go HAM on it it revs up about 1k rpm more than at shift point. But if I shift nice it revs about 2-400 rpm.
It's been tuned by C2 Motorsports, done by a certified mechanic, that's the only mod on the car, besides suspension. I bought the car and dropped 1100 to fix it to drive right, newish throttle body, and a major vacuum hose, and the tune within a month of getting the car and the tune was to mainly flash the ecu so it wouldn't pull two codes for a leak that wasn't there anymore.
Golf IV / Jetta IV :: 2000 AC Not Blowing Cold
I have a 2000 Jetta that doesn't blow cold AC. Here are the details:
- When the AC is turned on, air does blow through the vents. Each setting (1-4) does blow harder than the previous.
- Both front fans spin and are working
- The AC compressor clutch never engages
- All fuses (two inside the car and the one above the battery) have been replaced and test good.
- When the AC is on full blast, the voltage coming from the AC compressor wire shows ~9.3V for about 5 seconds, then jumps up to about ~11V for less than a second, this repeats over and over and the clutch never engages.
What the next logical troubleshooting step would be? I've read about this possibly being the fan control module (maybe) and also read about testing the AC compressor using an external 12V power supply, but am not sure where to go from here.

View 1 RepliesGolf IV / Jetta IV :: Air Condition Is Not Blowing Cold
I have a mk4 gli and the a/c is not blowing cold, or remotely cool. When I turn on the a/c the engine drops rpm's like it is engaging, or whatever, but doesn't get cold. I checked under the hook and it sounds like something is trying to come on every 10 seconds or so...it's like the engine jumps or something. The fan on the passenger side is coming on if that means anything but the driver side doesn't when a/c is turned on.
