Golf IV / Jetta IV :: 2001 - Coolant Indicator Light Turning On Intermittently?
Aug 12, 2016
My coolant indicator light keeps returning on my 01 Jetta GLS 2.0
I have searched in the forums and read that its likely a coolant sensor and requires replacing the coolant tank. I am wondering if there are other possible causes as I want to drive it for another 3k before replacing tank (as I will be having timing belt replacement and coolant flush at that time). Previous owner had universal (green) coolant in and it will be replaced with proper coolant when the flush is done.
The indicator comes on within a minute of starting the car. The thermostat seems to operate just fine and car is not overheating. I have topped off with diluted water, it definitely has proper level.
Safe to ignore as long as I watch coolant level and temp?
On a separate issue: I tried to use code reader but it would not connect to my car (had successfully connected at some point prior), I believe it may be because I have an aftermarket radio (the K-wire issue?). If that is true, should it resolve if I swap the stock radio back in? I need to be able to connect to the car eventually when it is time to renew registration (for state emissions control testing).

I've got some problems going on with my 2001 VR6 Jetta. I was driving home from my way to work this evening and all of a sudden the indicator light came on and told me to stop and check the coolant level. Within about three minutes the car was already up to about 200. I pulled over to a gas station and the coolant reservoir was completely empty. So I began to pour coolant in the reservoir and fill it up I notice I was pouring a lot of coolant so I went to the hood looked on the driver side below the bumper and water/cool was pouring out everywhere. I inspected as many radiator hoses as I could and did not find any cracks. The water seem to be pouring out from around the thermostat housing. My question would be since I don't know whole lot about cars would they crack thermostat housing because you need to have this problem?

I drive a 2000 VW Golf with 148K miles on it. One Saturday this summer my brake indicator light started lighting and beeping intermittently as I was driving. My brakes were operating fine so I did not read my owners manual until I reached my home. It indicated that I needed to have a qualified mechanic check it immediately but as it was almost 4 o'clock in the afternoon I couldn't find a mechanic in any gas station or garage. As I had a 200 mile drive to do the next day, I purchased brake fluid and carefully followed all of the directions for checking and filling my brake fluid.
However, when I took the cap off of the reservoir, the reservoir really looked fine and I was only able to add about a teaspoon max of brake fluid. However, when I tried driving the car, it seemed that the problem was solved as the brake indicator light did not come on again. Approximately 3 months later now the brake indicator light is intermittently going on again: about every other day. It goes on and then shortly after it goes off and then it doesn't come on again for a day or two.
Inasmuch as I added such a small amount of brake fluid last time I'm really not sure that the problem is actually with the fluid. I wondered if perhaps it was more of a vacuum problem or that by opening the reservoir some air escaped or something of that nature. I also wonder if possibly there's a component that's giving a false reading. At any rate, I'm a little white-haired old lady and there's a limit to what I can do on my car myself and I'm also a target whenever I go into a shop to get the most expensive diagnosis and fix. I'd like to go in to a shop with good information so that it doesn't become an expensive fishing expedition. What could be causing this?

Okay so recently I was driving my 2000 Jetta and the coolant temp light came flashing on, when I went to check the coolant I was surprised to discover that it was like a mud brown color, almost looks like peanut butter. From everything I have read this can be from a few things, either rust build up that is gunking everything up and oil getting into the coolant somehow. I'm pretty sure its rust build up but I was wondering what everyone thinks about this, I was also not using G12 coolant which I'm told now is the premier brand for VW's.

So my jetta is 2001 i believe and idleing like its got major breathing problems, it goes from 700rpms to 1500 in cycles and sometimes dies out all together. I thought it was some kind of vaccum leak and had a few pipes in the engine bay replaced but it didnt fix it. Its also missing a muffler so its really load and annoying, especially when im at inn n out in the drive through lol. Other than that, the car doesn't seem to be running that bad but the check engine light is on as well as the traction light comes on sometimes for no reason.

My oil sensor light goes off under specific conditions, and it's consistent and 100% repeatable.
It's an MK4 Golf GTI 5-sp Manual, and whenever I'm slowing down and the engine is under 2000 revs, the sensor light goes off. This includes stopping, slowing going down or up hills, and really anytime the engine is lower than 2000 revs.
I've replaced the oil sensor, no dice. I don't know what else the issue might be?

Just purchased a 01 golf 1.8t 5spd and noticed it has a small coolant leak.. Left parking over 2 days in the same spot and it builds up a little puddle.. It's dripping down off of my oil pan and I haven't been able to trace it back to where the leak is coming from..
I've been told it could be my water pump? The car has 92k miles.

I realized my horn is not working. I also realized that the left side turn indicator (blinker) light is not working and when I popped it out I saw the wires were chewed up, I am not sure what happened. Do you think I need to remove the wheel well liner to try to access that area? What to do?

Recently had this problem which started up about a week ago where my car would make this clicking noise whenever I turn left while driving. When I turn to the right there is no noise. Some said that it could be that CV joints need to be replaced. I have a video showing the side that is making the sound, maybe there is something abnormal that I don't see.

I drive a 2001 Jetta with the 2.8 v6 with ~125k miles
So for a while my car was giving me a false read on my temperature so I replaced the sensor. I actually followed instructions from a thread on this site. [URL] ....
Now when I go to drive my car, it runs sluggish and misfires if I really give it some gas. CEL is on(however does not return a code when hooked to a computer), and flashes when gassed hard.
I've checked to make sure spark plug wires were reconnected correctly and securely. No leaking has occurred from the temp sensor. shift rod drive unit is reconnected correctly.

I know this is a common problem, it sounded like the coolant resevoir was the place to start so I replaced it today and I still have the low coolant light blinking, I don't know what else to do.

I got an 02 gti automatic. My low coolant light has been coming on often lately. I checked my coolant level and it was real low. I added coolant and the light didn't come back on. After a few weeks the light came back on. Again I had to add a lot of coolant..I have no leaks though. Where could all this coolant I add be going? I am not over heating or anything. Its like my car is literally drinking this and peeing it out, I have to add some almost every week now for the light to stay off.

Mk4 Jetta Gli 1.8t , car was over heating only when sitting 5+ minutes at idle, mechanic said the big fan needed replaced so he replaced it. Car still over heated so i replaced the coolant with G13. It hasn't over heated yet but got in the car this morning and the coolant light started flashing and car was telling me to STOP the car. Checked out the coolant and it was on the low side. What it may be? Leak somewhere? Bad thermostat or water pump gone bad? Timing belt and water pump were done when i bought the car when it had less than 50k miles, car now has 99k miles on it.

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 ....

The remote locks on my 2000 Jetta GLX have been working intermittently for almost a year. I had been using the manual key to lock/unlock until finally the manual lock alarm disarm also became intermittent and I found myself stuck at a truck rest stop at 1:30 a.m. with my alarm repeatedly howling into the night and no way to disarm it. I felt caught. I felt trapped. Like I was found guilty of a crime I had never committed. I knew then - I had work to do.
My research in the forums indicated that the door lock assembly was a common culprit - a gremlin, often leaving headaches as it's only calling card. I worked quick, pulling a driver's side door lock assembly out of 2003 at the local junkyard and replacing it no problem. To my surprise, although this DID fix the manual locking/unlocking/alarm disarming problem, it DID NOT fix the remote unlock problem. The culprit was still at large.
Business as usual with intermittent remote unlocking/locking/trunk-popping for weeks until my dash threw the "AIR BAG FAULT" light. I decided to question a local garage owner who's VAGCOM told me that it was caused by something on the driver's side door. He was busy, but it reset fine and I was on my way. I know now that I should have asked for the code then but I was caught in the beauty of a girl who only nails polish was the grease and dirt of the car she worked under. And about a mile down the road, the light came back on.
Now, the "AIR BAG FAULT" light is on as soon as I start the car. However, the time seems to vary slightly before the Jetta beeps and tells me in faded red letters "AIR BAG FAULT". Sometimes right when I leave my driveway, sometimes not before I drive a mile or two down the road. My remote unlock is still working intermittently.
I need both my airbag fault and the remote unlock fixed. I'm wondering if these two problems are related? Like maybe there's a loose connection that is causing the airbag sensor to short and it's beeping when it bumps out of place and maybe the intermittent remotes are being caused by slamming of my driver's side door too hard & it's losing a connection as well. I tried putting a little conductivity jelly in the female clip that goes to the window regulator motor because I heard that the airbag sensor is in there somewhere but it didn't make a difference.

My buddy with his 2000 jetta 2.0 that starts then stalls. The immobilizer light turns on and off again as it should during the starting process. Tried reprogramming the key with the 2 key programming process, also tried removing power from the battery and touching the leads together but these are fixes for the immobilizer but the light doesn't stay flashing. Is there anything I can try while waiting for my vag-com scanner to be delivered....

Today was the first time my wagon has stranded me due to a mechanical issue. During city driving my coolant temp light came on so I pulled over to check it out. The fans appeared to be working, the coolant was a fair bit above the normal mark, but I'm not sure the water pump was running. I couldn't feel anything when I squeezed the top radiator hose. This is an '03 with about 50k miles on it.
I'll be taking it in Monday morning so I was curious what people's thoughts were. If it's the water pump is there anything else I should consider getting replaced while I'm at it? I'm still on the original timing belt, a change I've been delaying a long time since I drive so little so it might be time to bite the bullet and do it.

Car: 2003 Jetta VR6 GLX 24V
Sometimes when I start up my car ( I want to say when cold, but I haven't tried after its warm yet), the coolant light and warning come up. I obviously checked the coolant, and it is a little low. But it's been where it is since I bought the car, and I haven't noticed any leaks. After I turn the car off then on again the light goes away.
The car is running perfectly fine, it's not running hot or cold. Another thing I have noticed is that my fans don't seem to be working. ( I know it's a common problem). But I'm thinking this could be the fact that it's below 0 today.
I haven't gotten it scanned yet, but what's going on; i.e., Thermostat, sensors, fans etc..

Before I go buy a Bentley manual to dig around, when should my radiator fans kick on. I had the car idling for 10 minutes, no ac or heat on, and my coolant warning light came on, it overheated. It already has a new fan switch in the radiator, and the fuses are good.
