Golf IV / Jetta IV :: 2002 - Engine Works At 1100 RPM Whether Cold Or Warm All The Time
I have Golf MK4 1.6 16V BCB '02 and problem while engine is running on idle. Engine works at 1100 rpm (doesn't matter is it cold or warm engine) all the time.
Dashboard turns CHECK ENGINE and EPC lamps and says : "engine workshop". At the beggining of problem VAG-COM diagnostic found this error:
17953 - Throttle Valve Controller: Malfunction
P1545 - 35-10 - - - Intermittent
But after I've changed my old throttle body with new one VAG-COM diagnostic haven't reported any error (no permanent error) and idle issue stays.
While engine is running and Check engine and EPC lapms are turned on diagnostic reports this error:
17961 Barometric/Manifold pressure signals: Implausible Correlation
P1553-35-10 ----Intermittent
After engine is turned off diagnostic doesn't report any error!
Beside of changing throttle body, I've changed ECM, MAP sensor, temperature sensor, EGR valve, . Also checked intake manifold and hoses if is it leaky (doesn't leak anywhere), and timing belt is ok and checked complete wiring installation!!!
Golf IV / Jetta IV :: 2002 VW 1.8t - How To Replace Fuel Line
I need to replace the fuel line that connects to the fuel rail, it is old and corroding and drips out gas when I dry so I need to replace it. I have the new fuel line for it but how would I go about taking it off and the clamps? Just wanna make sure I am doing it right.

Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car, HVAC isn't my cup of tea I don't know anything about it. What else could be the problem? I can live without A/C but the heat things must be fixed.

So i just had my R32 at the stealership to get my AC recharged. Ever since ive noticed that my AC doesn't always blow cold. It will vary from cold to warm and back to cold then warm. Im not even sure what to start looking for as the issue

I am trying to narrow down what could be the issue to my 2002 vw Jetta VR6 air conditioning. It is blowing air but the air is not cold. If I need to add refrigerant, where I can find the low pressure valve so I can do this on my own with one of those store bought cans.

View 1 RepliesGolf IV / Jetta IV :: 2002 GTI - Loud Whistling Sound On Cold Start
I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.
When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.
Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.
I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.
Golf IV / Jetta IV :: 2002 - AC Quit Blowing Cold / Compressor Need To Be Charged?
The AC on my car (2002 Jetta 1.8t) quit blowing cold. Did some troubleshooting and...
1. Checked Freon- level was ok
2. Noticed cooling fans were not coming on with AC button pressed and ignition on. Fans also not coming on when car up to temperature, but gauge never went above normal. Seems strange considering I live in Houston and it was 95+ out.
3. tested fans with direct power and both high and low are fine.
4. jumped terminals 1,2 and 2,3 on plug for cooling fan switch and fans turn on high and low...so thought must be bad cooling fan switch.
5. Replaced cooling fan switch and still no fans or ac when AC button is pressed and ignition on.
6. replaced Fan control module. Still no fans.
7. Checked Freon once more...and although it was in the ok range decided to add a little more. (was in the middle of ok range, and a cheap gauge)
8. Compressor kicks on, along with cooling fan. End up using the 1 can I had and now have cold air and fans that come on when hitting the AC button with ignition set to on position.
I thought the mkiv cars would always turn on the fans when AC button is pressed with ignition on? Or does the compressor also need to be charged?
Volkswagen - Cabrio :: 2002 Won't Start Until Gauge Is Completely At Cold Line
My 2002 Volkswagen Cabrio won't start when it is hot, only when it is cold. Several times in the last few months, similar experiences such as the following has occurred. Yesterday, I drove approximately 15 miles, ran into a store for about 10 minutes and went back to the car and it started. Then drove about 10 miles and shopped for groceries for about 45 minutes, returned to car and it started. Drove about 10 more miles and went into a store for about 30 minutes...car wouldn't start. The engine does turn over. As the temperature gauge descends each line, I try to start the car and it will not start again until the gauge is completely at the cold line. My husband has replaced the battery, both temperature sensors, changed the fuel filter, changed the ignition coil and the starter in March.
One other time it gives me problems which is different than the above scenario is I have driven the car just one or two miles and had it off for only two minutes to five or ten minutes and could not start it for an hour or so.
An OBD scanner at an auto parts store gives several code readings, some of which say it is the fuel pump primary circuit, cylinder 1,2,3 & 4 injector circuit low, secondary air injection system relay A control circuit, evaporator emission system purge control valve circuit is shorted and, finally, evaporator emission system leak detection pump control circuit low. I have had readings done before by an OBD scanner and the problem didn't have anything to do with what the scanner said so I don't have much trust in those readings.
Camry :: 2002 XLE - Cold When Running Down Highway But At A Stop - AC Gets Warm
This is a 2002 4 Cylinder Camry XLE.It gets cold when running down the highway, but at a stop , AC gets warm.I have replace the cabin filer. A couple of years ago, replaced the AC MAG Clutch Relay, when AC light was blinking.But now I feel the condenser in front of the radiator and it feels very hot, and the fans never seem to come on.I can see the 3 Fan relays, and not sure where the ECT sensor is located, or whether that would be the problem.If the fans arent coming on at all, you would think the car would overheat?
Tested the motor on one of the two, with direct 12 volts to it, and it did not run.Tested the disconnected cable that would be supplying voltage to that motor and it read 13+ volts. So I would think it was a bad motor, but I would like to see the voltage on that disconnected motor go to zero, but not sure if that happens, or when?Guy suggested at parts place that sells the Two Motors, Fans, and Shield all as one unit for less than $100, that maybe the motor burned out because it was running all the time.
WHen should the electric motors not be receiving power?I read somewhere that when car starts that both are on low speed, and Always on when AC is on. But do one or both ever turn off? If I pull this shroud out with the two motors and buy the replacement, I just don't want to have the motor blow out, because there is something making it run all of the time.
Golf IV / Jetta IV :: 2000 AWD 1.8t Overheating - One Side Of Coolant Line Hot
After finally getting some issues sorted this weekend (needed a transmission flush) I was driving around a bit to make sure everything was good. On the way back to my house, the car started overheating. I replaced the thermostat this winter (~4-5 months ago) because it was stuck open making things run a little cool.
I was thinking the water pump is probably shot but not 100% sure. the radiator fans both work and when I turn on the heater, it blows hot. Any good way to check if the water pump is dead? I have a little point and shoot infrared thermometer and one side of the coolant line was way hot and the other was fine (cold ~90 deg F).
Golf IV / Jetta IV :: Rear Wiper Fluid Line Leaking
I have a leak in my rear wiper fluid line on my GTI. When I use the rear washer, I get a pool of fluid in the driver side taillight and under the rear seats. I'm getting some fluid in the rear driver side headliner as well so the break must be there. First step is to pull the headliner.

It appears the Engine By fuel line connectors are broken. I searched for DIY'ers on how to fix, but so far I only see those related to fixing other sections on the fuel line, not this upper section. It's on the passenger side. How to fix it?
View 3 RepliesFord Super Duty (1999-2016) :: 2002 F250 - AC Blows Cold For About 15 Minutes Then Air Gets Really Warm
I am the proud owner of a 2002 F250 Super Duty 4x4, which has 158K miles on it. I live in South Florida and use the truck as my daily driver and also from trips up into the Blue Ridge Mountains.
Recently, I noticed that when I have the A/C on it blows nice and cold for about 15 minutes, but then the air gets really warm. I had the system checked and the Freon levels are right where they should be. A bit of experimenting reveals that if I turn off the A/C for about 10 or 15 minutes after it starts to blow warm air, the systems blows cool air as it is supposed to.
Therefore, I suspect that something is freezing under the hood and preventing the system from operating properly. Since A/C is pretty well essential for us in south Florida, this is a problem, when I have the family or customers in the truck.
Golf IV / Jetta IV :: AC Gets Warm When Accelerating
When my car is at idle or cruising the AC works well. When I'm driving normally from stop light to stop light the AC gets warm.
I did have the pressures checked and they topped off the refrigerant. They also said the compressor is working well. I had all this checked before it started getting warm during accelerating.
Are there some things that I can look at?
Golf IV / Jetta IV :: Brake Vacuum Line Is Cracked After Check Valve On Intake Side
Question, I have a 2003 VW Golf GLS 2.0L AHV (5 speed). The brake vacuum line is cracked after the check valve on the intake side. I looked up the part number on the hose (at work and don't have it on me at the moment), did some research and noticed some revisions to that part number. Eventually settled on [URL] ..... (I ordered a new one since I needed to order a few things). Needless to say, I am beginning to think I ordered wrong.
I noticed that the check valve on the new hose has a 3rd piece that a smaller hose looks to clamp on? The check valve that is in my car doesn't have that. Did I order the wrong part? or did I need to be a cap?
Golf IV / Jetta IV :: VR6 Won't Start When Engine Is Warm
Mmkay.. 2000 GTI VR6.. Will start initially, when engine is cold (sat overnight, or through the work day) but once the engine is at normal running temp, if you shut it off, it wont start. Acts like its out of gas.. have to "prime" and keep hitting the gas pedal while cranking, to (sometimes) get it to start when warm, and then it runs like crap until I get a few miles down the road.
Brand new plugs and wires, and just this evening, pulled a plug, and its obviously fouled, and covered with unburnt gas. Coil Pack maybe?
Golf IV / Jetta IV :: 2001 - Won't Idle After Warm Up?
I swapped transmissions in an 01 vr6 glx automatic car. The car will start and run perfectly until it reaches operating temperature. Once it hits 190 f it shuts down and will only start again if u wait a few minutes. It has me stumped. I have unpluged the coolant temp sensor, and Have checked for vacuum leaks and loose connections but no luck.

I've got a 2004 wagon and occasionally, when it's warmed up, if I shut it off it's hard to start again. When I turn the key it fires up, but when I release the starter it dies, like I've shut the car off. Giving it throttle makes no difference. I have to do this several times, and then it keeps running. Never does it cold. No codes.
