Golf IV / Jetta IV :: AC Slowing Down / Refrigerant Low
My AC is slowing down and needed diagnostics. Fan system is fine. So I hooked up my manifold guage set from HF and got 90 on both high and low static, and 35/175 under load. Temp was 83 Fahrenheit with 36% humidity.
My diagnosis - refrigerant low. (i.e. low/low)
So what kind of quantity can I assume I'm down? Do these german ac run on the high side? I'm going to pour in the PAG 46 myself through the yellow line, and that runs roughly 5 to 1 to the refrigerant. NO SEALANT. Just a 12 ounce can of 134a and 3 ounces of PAG 46.
Just to verify - it is PAG 46 for the 2004 Jetta 2.0 GLS?

View 17 RepliesGolf IV / Jetta IV :: Revs Just Drop Down To 0 And Engine Shuts Down While Slowing Down
Looking for some hint regarding V6 AUE ? Regardless if engine is warm or cold, sometimes happens to me that during driving, while slowing down and pressing on clutch pedal, revs just drop down to 0 and engine shuts down (vehicle still moving). This usually happens while changing gears from 3rd to 2nd on low speeds in city, or while slowing down to full stop in 2nd gear and pressing clutch pedal.
While this happens, I quickly switch off the ignition and start the engine again, which is tricky and potentially dangerous, since vehicle is still moving but my power steering and brakes are not functioning because of stopped engine.
Some relevant info...I have K&N cone air filter intake and ECU is remapped by BTS Racing (German tuning house).
Car is running and pulling normally. In all other regimes of driving, there are no issues or whatsoever.
Prius (2004-09) :: 2006 - Three Warning Lights When Driving And Slowing Down At A Light
my much adored 2006 prius just got three warning lights as i was driving and slowing down at a light. The big red triangle- "Master Warning", the Brake System Warning, and also, the Hybrid System Warning. It was like warning lights galore... i'll bring it into the dealership first thing tomorrow, but any clue what's going on? I regularly maintain it. The only other thing that ever went wrong with my car is that the touchscreen quit working years ago, and i refused to spend the 3k for them to connect a silly wire. Why my lights went on and is this something serious?
View 7 RepliesGolf IV / Jetta IV :: 2004 GTI VR6 Cutting Off After Driving About 20 Miles
2004 GTI VR6 24V Manual trans. My son's GTI has an intermittent problem that I think will be hard to pinpoint because it is intermittent. I will hopefully have more info this afternoon. Three time now after driving about 20 miles the car will cut off. Usually while slowing down to a stop or to make a turn. So far it has run great at highway speeds.
It has some random symptoms. I drove it to work and it happened to me. The first time I had slowed to about 20 to make a turn and it cut off. I made the turn and let out the clutch and it bump started and I made it to my work parking lot. While turning into the lot it cut off again so I coasted into a parking spot. This part has me puzzled it would not crank the starter. I moved the gear selector to every gear and nothing. I put it in reverse and the starter would crank but would not start.
Came back about an hour later and it started fine and acted like nothing wrong. Drove it home and again about 20 miles and it cut off again. This time it would crank in all gears but would not start. This time the EPC light came on. Left the car and came back later that night and it started fine, EPC light off and drove the last two mile home no problem. I am borrowing a friend from work computer with the VAGCOM software and hopefully will have more info.
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 :: 2004 - Check Engine Light Flash When Driving
My 04 GTI 1.8T got the infamous codes P0300, P0303 and P0301 yesterday morning. The check-engine light flash when I drive it. It is a little rough when the check-engine light flashes, but it is drivable and nothing major. When the car idle or when it come to a complete stop for 15 seconds or so, the check-engine light goes away and it comes back after 15 seconds or so after took off from stop.
I cleaned the MAF last night, but the check-engine light still acts the same way as yesterday on the way work this morning. The codes refer to miss-fire. This is my first VW.
Since I can easily get sparkplug from Checkers, I'll try it first. Checkers carries Autolite, ACDelco, NGK and Champions. Which brand do you prefer for VW engine? I hope that it is not the coil pack. It is expensive for $30 each at ECS Tuning.
Jetta - Volkswagen :: 2011 - Stalling Typically When Slowing Down
We purchased our 2011 Jetta SE Automatic brand new - first people to drive it - and have had virtually no problems up until this summer. The car has stalled on us dozens of times now and been to two different dealerships for service a handful of times and no one knows what the problem is. We found that the car typically stalls when we're slowing down; however, it recently stalled when we were in Park. When it stalls, the steering wheel locks up, the breaks are nearly impossible to push and everything seems to shut down except the radio. We're virtually a sitting duck for other cars.
When this happens, we're able to put the car back in park, turn it off and back on and drive fine for a while. It seems to be happening more frequently but the dealership hasn't been able to replicate the issue - there are no codes left on the computer and they've literally taken the car apart and can't find anything wrong. They've even 'driven' it for 200 miles and still, nothing. Initially we were told it was bad gas, then we were told it was an operating system update. Now they're trying to tell us that it's our driving style but multiple people in my family have driven the car with the same effect - stalling spontaneously while slowing down, stopping or trying to break.
We've also noticed skipping or slipping between gears when we're at higher speeds but I'm not sure if that's related. It almost feels like your foot falls off the accelerator or slips while you're driving but instead you're actually applying constant pressure.
Jetta - Volkswagen :: 2012 TDI - Brake Pedal Went All The Way To Floor Without Slowing Down
Brand new 2012 jetta TDI (less than 1,000 miles). Standard, 6 speed. A few weeks ago, I went to brake, and my pedal went all the way to the floor (no resistance) w/o slowing me down. I let the pedal out (after freaking out a little), and when i went to try again, the brakes kicked in. I was a block from home, so I continued to drive, pulled in to park, and it happened again. Left foot on the clutch, right foot went to brake and went all the way to the floor. Took it straight to the dealer. They checked it, drove it, checked it again. Couldn't find anything.
I've driven about 500 miles since, with no incident. Then, it happened again. My brake pedal literally touched the floor, and didn't even slow me down. I tried pumping. Nothing. Took the pedal all the way out, and then recompressed- worked fine. Drove it to the dealer, happened one more time on the way (had to pull the ebrake to stop).
They have had it 2 days and still can't find anything wrong. I've been driving VWs since I got my license. I've never even owned an automatic, so the whole "maybe you were pressing the clutch instead of the brake" comment is out of the question. What is going on?!
Santa Fe (CM - 2007-12) :: Loud Thud While Driving After Slowing Down Then Giving Gas
My 2011 Hyundai Santa Fe as reached 40 MPH. While driving, after slowing down then giving the car gas, it would make a very loud thud and I would be jolted forward. At times it sounded like the transmission was going to be left on the roadway. Is it common problem?
View 2 RepliesFord - Contour :: 1999 - Jerking While Driving Accelerating Slowing Down
I was driving the car yesterday and was getting on the highway ramp and stepped on the gas and car went crazy. It started to accelerate and decelerate by itself. I had no control of the car whatsoever. When driving at 0 to 40mph no problem so far, but anything over this car will jerk, like it's changing gears by itself, 'going fast and slow.'What is this? Do I need a fuel filter, or plugs or what? I don't know when the last time I changed anything the car mileage is 135,000

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

My car is a MK4 Golf 2.0L .. Standard I was stopped at a stop light and I started going everything was fine til i got to 3rd gear. I was in gear but nothing was happening I would push the gas and you could hear it turning but I wasn't moving the only thing is i could hear a little grind.

View 9 RepliesGolf IV / Jetta IV :: 2001 - Gas Cut Out While Driving
My girlfriend recently picked up a 2.0 Jetta, had her dad drive it 800 miles with no issues except a code for needing a new thermostat. A few weeks ago, we were out for a drive getting on the freeway and all of a sudden the gas just cut out on her. Then on a separate occasion, did the same thing except this time the power steering was gone and the brakes wouldn't depress. I told her to click it into neutral and then back to drive next time it happens, so she did and then it was like nothing ever happened. Weird, right? I don't really have any leads on where this could be coming from, since it's so intermittent.
View 2 RepliesGolf IV / Jetta IV :: VR6 Pulls To The Left While Driving
2000 jetta vr6 145k.
So when I bought this car it was not driving and hasn't been driving for a year or so, needed time chains and the whole 9 yards. Did that, everything is up and running as well as new brakes all around, snow tires until I can afford some all season.
While driving, only in gear, the car pulls to the left. Even with a touch of the gas pedal it's pulling left. As soon as I let off its going right. If I coast in neutral it holds straight like an arrow. I have replaced the bushings for the dogbone and trans mount with polyurethane thinking with the high mileage it would be the culprit. The control arm bushings seem to be ok, neither side has any play, no wheel bearing play, no tie rod play....so I'm stumped.
Golf IV / Jetta IV :: 2002 VW GTI 1.8 T Died While Driving
I was recently driving home when I made a left hand turn and the car died. I had the timing belt and water pump replaced 1,800 miles ago. It sounds like a timing issue to me. The last time I had timing issue it wouldn't run. This time it runs. Attached is a video of me starting it with the camera looking at the timing belt. The noise I heard made me shut it off. I did not want to cause more damage.

Golf IV / Jetta IV :: EPC Light Came On While Driving Down The Interstate
SO like the title suggests i had my EPC light come on while driving down the interstate. I was on cruise and had been for about an hour. then the motor seemed to stall and then pick up right away but wasnt at full power. i had the gas pedal to the floor and was losing speed. the cruise had come off as soon as the motor faulted. the light stayed on constant and i did not get any other lights or sounds to accompany it.
I pulled off at the next exit and stopped in a parking lot. I turned off the car and then turned the key to see if my check engine light was still operating. it was so i listened to the car as i turned the key on completely. I didn't hear any odd sounds and the EPC light was no longer on. I pressed the gas pedal and the motor responded with full power. Not sure what would cause this 2 occur but I am concerned that it may happen again and i may get stuck somewhere.
Golf IV / Jetta IV :: 2002 - Powers Out While Driving
I drive a 2002 Jetta with a turbo engine. In the past 2 months, my car has 'powered out' or shut down while driving - I can't accelerate, it is hard to steer, doesn't really brake well and although the dashboard lights remain on, my car dies on me. So far, I have been able to restart the car with little problem and she usually starts on the 1st or 2nd try. My dealer/mechanic had the car for a day, test drove it numerous times, checked the computer, battery, connections, etc. and can find no reason for this behavior. The last time this happened, it was raining outside; I don't remember what the weather conditions were the first time this happened. I have kept the car well maintained throughout the years.
