Golf IV / Jetta IV :: 2001 - Engine Overheating - Coolant Temp Sensor Replacement
My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
Golf IV / Jetta IV :: Overheating - Temp Stuck At 190 Usually For About Ten Minutes Then Starts To Climb
I am trying to troubleshoot an overheating problem so that I may fix it myself. Not sure if it's thermostat, sensor, or a blockage.
'04 Jetta tdi with about 200k miles. Temp sticks at 190 usually for about ten minutes then starts to climb, varying between the 207-225F mark. Hasn't gone any higher, even in high 90sF ambient temps after 30mins driving. Holds fluid fine, pink G12 mix, and no bubbles or milky appearance to oil dipstick. Recently installed new AC compressor, txv and dryer so I imagine I can tackle thermostat or sensor if need be. Where to start?
Golf IV / Jetta IV :: Overheating At Idle - Temp Gauge Starts To Climb To 3/4 Instead Of Halfway
I got a mk4 where the temp gauge starts to climb to 3/4 instead of halfway when I'm idling for a while.
1. fans don't come on
2. if I turn on ac, fan come on and temp stays at 1/2
I tested low and high speed on fans. both operational. Is it the fan control module, temp sensor green top, or radiator s/w?
Golf IV / Jetta IV :: Overheating / Temp Gauge Starting Raising Pretty Quickly When Driving
I have a 2002 Volkswagen Golf 2.0, I was driving and the temperature gauge starting raising pretty quickly. I stopped, checked the coolant and oil, both were at normal levels. The car cooled down pretty quickly, and I drove a little and it raised again. The heat is coming out cold despite the hot temperature. Overheating, normal coolant levels, no heat.

So i replaced everything, Crack pipe, thermostat, greentop CTS, water pump... still getting 1 or 1.5 bars past the vertical in traffic after about 10 minutes...
The fans work... atleast they are both on when i shut off the car...
Golf IV R32 :: Slightly Overheating In Traffic - No Big Fan When Running AC
I was slightly overheating in traffic, watching the gauge creep up a little. So i bought a new fan, swapped it in this morning, and still no Big Fan.
Fuses on top of the battery are all good. Does this mean my FCM is gone?
Golf IV / Jetta IV :: Engine Overheating - No Leakage
Ok I have an automatic 02 gti..the other night as I was driving home it started to overheat And fast..I had to stop about four times to get home so it can cool down a bit..the next morning I went to check for leaks but I didn't have any and my coolant level was good..I turned the car on and let it heat up and I noticed the fan didn't kick on..is the fan not turning on a good sign that it is bad? I ordered a timing belt kit from ecs which came with a new water pump and thermostat but I didn't get to switch everything out in time and now im stuck with a overheated engine..the only thing I did change was the coolant temp. Sensor because it was the easiest thing to change.

Engine will overheat unless I turn the AC on. The engine fan only operates with the ac on it seems.
Will not overheat unless in traffic for a while.
Would it be radiator thermo switch or the Fan Control Module?
Golf IV / Jetta IV :: 2013 - Engine Temp Warning Light
Whilst about half way into an 8 hour drive to NYC my engine temp warning light goes off.
Blast the heater and pull over at the next closest rest stop.
No leak to be found. Looks as though the coolant level is okay Burk can't tell since the car hasn't cooled down yet. Engine bay doesn't seem crazy good. No strange smells.
Turn the car off then on and the warning turns off. I let the car cool for 20 min then back on the road. Warning comes on again on the highway.
What it could be? Possibly the thermostat? Could this fix itself?
Golf IV / Jetta IV :: Temp Light Comes On With Keys In - Engine Cold And Not Running
So my temp light comes on in my 2002 gti 1.8t. The light comes on with the engine cold and not running, just keys in. I replaced the temp sender and the fan switch. I already checked the fuses, still good. The only thing i can think of now is the relay. There is plenty of coolant in the system as well. And I am not getting any CEL.

I have a 2005 mk4 gli and the other morning I went out to start my car for work and all I got was crank no start. I then realized my fuel pump wasn't priming when I opened the driver door. After work I came back and checked the fuel pump fuse and swapped the relay with another I had, still nothing. A buddy of mine came to me and decided to check the connector at the fuel pump for power, using a power probe I believe he hit all or the majority of the wires with 12v of negative and/or positive power. He then unplugged the connector and plugged it back in and the car fired right up. But I noticed that my fuel gauge, engine temp gauge, and outside air temp readout were all not functioning.

My CEL is on for P0116 Engine Coolant temp circuit, range or performance problem. I replaced the CTS, thermostat, and did a complete coolant flush/replacement last November. Car worked well over the winter no issues. Last week when the CEL came on it gave me P0301 and P0440 as well. I did a reset and the lights stayed off for the week. Then P0116 came back. Is it possible that the CTS is bad again? I measured the resistance on the CTS and hot it is about 300 ohms and cold is 2.45k ohms.

Last weekend we noticed that the engine temp was spiking. I still does. Sometimes it's a matter of just 8 blocks of driving before it's up, during which the heater doesn't want to blow hot air. Or, it will have a normal operating temp around town, and then start to spike when we hit the highway, and the heater works fine then (it even seems to take some of the temp off of the engine, like it should.) I took it to Autozone to have them run codes and it came back with a faulty coolant temperature sensor (I don't remember the CEL code.)
I have the replacement sensor and can replace it, but I'm not convinced that this is the problem anymore. Yesterday I had the coolant flushed, but I still have overheating issues. In fact, it seemed to be worse on the ride home from the coolant flush. Anyway, I noticed riding back from Autozone today that it felt like the engine was braking, as if my car were a manual. Now, I've ridden a few manuals before, and the braking I felt wasn't as heavy as the braking you feel when you release the accelerator and the clutch is still engaged, but it's similar. I think I'm a little overdue for a transmission fluid change. Could that be it?
My Mazda3 is a 2008 automatic with the smaller engine. It's stock.
Golf/GTI VI :: Overheating / Temp Gauge Slowly Rises When Going Faster Or Accelerate
I have a 2003 vr6 with about 60,000 miles on it and it overheats. I can drive between 35-40 mph and make short trips no problem but when going any faster or accelerate faster than an old lady in a buick, the temp gauge slowly rises(or fast if i accelerate fast.) Until the "stop, check coolant" warning comes on(which i don't let get to that point.) it blows heat all the time, all the hoses get hot, I am no professional by any means but i have dealt with many different overheating issues with other vehicles but I am kind of stumped at what to try first so i don't end up replacing something that doesn't need to be because i do not have the extra $ to do so. The problem started when someone put dirt in my coolant, I flushed out the system twice, the second was just to see if anything else had loosened up that I may have missed the first time..
View 2 RepliesGrand Prix :: Overheating But Temp Gauge Not Going Above Normal Operating Temp
I have a 2004 Grand Prix and it is displaying the symptoms of overheating but the temp gauge is not going above normal operating temp. I replaced the thermostat twice, and after driving for about 10-20 mins coolant comes out of the overflow. I'm at a loss, I'm thinking temp sensor(?) But I don't want to keep throwing unnecessary money into it. The fans work fine, the heater blows as it should.
View 8 RepliesGolf IV / Jetta IV :: Lights Keep Flickering Slightly
I have an 03 Golf VR6 and only has 76k on it. Ive only had it a week but I have come to notice a couple peculiarities. So first off at night regardless of speed or RPMs, ALL OF MY LIGHTS have a slight flicker. Its not a huge difference, but its definitely noticeable. Engine runs fine. No battery light. Additionally, twice when I go to start it in the morning, after starting the alternator workshop light will kick on. after giving it a tiny bit of gas it goes away and doesn't come back. Everything else seems fine. no check engine lights, no trip meter resetting, and the flickering seems to be sporadically. Tonight I tested the battery and alternator and both tested good. My only thought is that it might be a loose ground. Tomorrow I plan on taking a look at the ground under the battery. I've tried searching the threads here, but Im having trouble finding any relevant info. Also, is the voltage regulator inside the alternator, a separate piece, or in the ecm?
View 7 RepliesGolf IV / Jetta IV :: Popping Slightly At Idle Occasionally
So I just noticed now that my car is popping slightly at idle occasionally...It doesn't do it all the time and the idle is kinda lumpy but always holds at 800-900. Sometimes it drops a bit lower.
Also when starting it up in the morning, or when the engine is cold it doesnt rev up to 1500rpms it just starts and immediately drops to 800-900??
When I press on the gas and keep the pedal at one spot, say 2000rpms, it slowly drops down to 1500??
Golf IV / Jetta IV :: Add Brake Fluid As Level Slightly Low?
The brake light came on randomly yesterday, flashing foe about 5 seconds, then shut off. Hasn't come on since, but I looked at the brake fluid resovior and the level is about .5cm (.2inches) below the "min" marker.
Can I just open the resovior, pour in the fluid, recap it and go? I remember hearing from someone that if you open the resovior cap at any time, air rushes in and you must bleed the entire system before you can drive again
Golf IV / Jetta IV :: Car Automatically Adjusts Headlights Slightly As Driving
I'm trying to adjust the headlights on my Jetta wagon. I know the basic way to go about doing that theoretically, but how to actually adjust the headlights? Are there screws or something somewhere? I also thought I read somewhere that the car automatically adjusts the headlights slightly as your driving? How do I account for that?
