Passat - Volkswagen :: 2002 - Only Cold Air Blowing When It Is Supposed To Be Heat
I have a 2002 Passat that is only blowing cold air when it is supposed to be heat. I have checked the following items:
1. Both heater hoses are hot at the heater core which would indicate that the core is not restricted.
2. Air has been bled at the heater core and the antifreeze is at the correct level.
3. Car thermostat is operating correctly and maintains a steady 190 to 195 degrees.
4. When temperature control lever is moved from "cold" to "hot" the air noise definitely changes like a damper is moving but there is no change in air temperature. This is a manual control with cables (not digital read-out).
From what I have read so far I am convinced that there is a problem with the blend door but referring you back to #4 (air noise change) I believe that the cable is moving the damper. Can the blend door be accessed on this car without removing the center console? Can it be accessed through the glove box area?
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.
Golf - Volkswagen :: 2015 - Strange Whining Noise On Cold Starts
So I posted here a while ago with a question regarding my Golf and a strange whining noise it made on cold starts. I took it in to the dealer to find out what was going on (warranty) and they said it was the secondary air pump making the noise and that it was normal.

2002 Golf TDI . I am having a no start problem. I get all of the dash lights, the battery is fine, and there is just nothing when the key is turned. Our 2002 Golf TDI, now, of course, almost 15 years old. The dealership detects nothing through a computer read, and I'm down to the starter, relay and neutral switch as possibilities. The battery is just 3 years old, and we are at just 68K.
Can a neutral switch be tested for proper operation? Can the electrical system by tested for a starter motor or relay fault? The dealership maintains I need to await failure before they can do anything. We've had previous VW electrical problems w/this car - several dead batteries, complete on-board computer failure after having the car several months, way back when, and that part has been fine since then. I sold my last VW, a 1974 Karmann-Ghia Coupe, a few years ago, and these under-the-hood diesel setups are beyond me.
Golf - Volkswagen :: 2002 - White Smoke At Highway Speeds
I'm driving my wife's 2002 VW Golf on the highway to build miles (it's at 84k). It's a manual with gearing that's at 3500 rpm at 70 mph in 5th gear, which seems pretty high. It had been doing fine on the highway, even though the RPM seems a bit high due to gearing, but it keeps me under 80 mph (highway is largely 70 mph). It burns oil, but not too bad, like a quart every 500 miles or so.
Recently, when driving at "high" speed (slightly over or near 70 mph), I get a plume of intense white smoke. After slowing down, the plume goes away, and I can continue near 65 mph.
After this happened today, I put on a code reader, and saw of P0159, air fuel ratio oxygen sensor issue. What causes the white plume of smoke, and what to do about it? Seems like the car should have more miles on it.
Golf IV / Jetta IV :: 2002 - Overheating When Go For A Drive
So my 2002 Jetta 1.8t is overheating. The water pump was bad. Replaced. The thermostat. Replaced. Radiator. Replaced. Radiator cap. Replaced. We're running out of things to replace! I'm ready to go to a junk yard and get a new block! We've tried about 100 magical "ways to burp it" with no luck. We even tried running it without a thermostat. Without the heater core. EVERYTHING.
The car runs at operating temperature at 4 RPM. But when we take it for a drive, it overheats. There's no heat with the thermostat in unless you rev it at the high RPMs. As for the hoses, top is hot, bottom gets hot. As for the car, it runs beautifully. It gives no codes. No smoke either. Nothing in the oil, nothing in the coolant so I don't think it's the head. It just overheats. This has been FAR too long.
Golf IV / Jetta IV :: 2002 VW Overheating As Soon As Take It On A Highway
My 2002 VW Jetta GLS 1.8T 5-Speed is over heating
Car is still over heating after replacing the following:
- Head gasket
- Coolant fan module
- Geba Metal Prop Water pump
- Full timing belt kit
- coolant fan switch in Radiator
- Bleed the system of all air blow hot air
So Driving the car around town is ok, doesn't over heat, but as soon as I take it on a highway it over heats. I drove it 50 kms out of the city and it over heated, let it cool down and added water. got it back home. Oil light flashed on as I pulled into driveway, turned it off right away. no external oil leaks. Checked coolant, Oil in coolant. also the coolant was boiling, the level was raising up and lowering. I have been reading the forums for a few hours and the oil in the coolant sounds like the oil cooler gasket. Ok so the fans are running and it still over heats. The old metal propeller water pump was very hard to turn so I replaced it with a Geba Metal water pump. no leaks at water pump. Could it be possible that the Oil cooler was causing air to leak into the cooling system causing the coolant to boil? And then when the oil cooler "o-ring" finally failed it dumped oil into the coolant?
Golf IV / Jetta IV :: 2002 - Overheating In Traffic - Fans?
So i have a 2002 1.8t that i got in december. Everything has been great so far untill the other day the car overheated on me in traffic. It was a bit warm out maybe 75-80 degrees. I saw the needle start to climb and then the light went on so i through the heat on full blast and it dropped the needle a bit and turned the light off long enough to pull off the highway. I let it cool down and checked things out. I am not low on fluid, an the fluid was changed within the last year with the vw recommended stuff. The radiator hoses are pressurized so i believe that the pump and thermostat are working. I am thinking it could have something to do with my fans. I tested them in my driveway by supplying them with 12v and the spun perfectly. It only happens when the car is standing still for a period of time. Driving at any speed is fine. Is there some sort of switch that tells the fans to turn on?

My son has a 2002 Jetta, we just changed the water pump and the thermostat. The car will sit at idle and the temperature will stay around 190. When you drive down the road the temerature will rise and when you let off teh gas the temperature goes back down. What this could be, I have tried everything I can think of to fix this car.

View 1 RepliesPassat - Volkswagen :: 2001 - Engine Overheating / Fluid Leaking
Another month and another problem to be resolved. Here goes: The 2001 Passat 1.8T has had a hard life in the past year. The specifics are listed in previous posts. Most recently, the radiator was replaced because the engine was overheating again. The car has been leaking fluid ever since but it is not radiator fluid. Yesterday, I took a look at the oil and found tan gunk mixed in with the oil. I must admit that I had concerns after the fact about the shop that did the last oil change. Is it possible for mechanic to screw up the head gasket while replacing the radiator? It was fine before the repair. Is there another source to look for the seepage into the oil? Basically, the question is - Is the car destined for the graveyard because of this?

This is what its doing... Im starting to feel lost about whats wrong. I start it up and everything is fine. With in about 10 minutes it starts to bubble and spit out a little water then shuts its self off. And the gauge on the dash never reads above 190. And the fans don't come on unless i turn the ac on. And the ac still blows cold. The lower hose stays cold. I just replaced the thermostat and the water pump. But it changed nothing. Im thinking maybe its clogged somewhere. Maybe in the heater core or the radiator.

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?
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!!!
