Passat (B5) :: Computer Started Beeping Saying Stop / Check Coolant
Jun 30, 2005
About a month ago, I started my car and the computer started beeping saying STOP! check coolant...so i did....it was on empty...this was rather weird to me because i remember seeing it on normal like a week ago....so i added the coolant to the max level in the tank.....Two weeks later it was on the MIN level line....so i added some again....then a week later it decreased a little again.... it would seem that its a leak....however i do not see any wet spots under the car...it seems that the coolant disappears due to driving the car... Could it be the coolant? Also, how does G12 coolant differ from regular coolants sold in auto stores?

Pulling out of the driveway my 2004 Passat's computer told me there's an issue with the coolant and that I should STOP, so I pulled back in. My VW dealer has this coolant in stock (G12, red) but considering it is 7 degrees outside (or minus 14 C) I wonder whether I can't ignore the warning and drive the 2 miles rather than get on my bicycle.

When I got the STOP check coolant level message on my 2002 Passat glx. I pulled over as soon as I could and then I began to over heat. The coolant level was good, actually it was a little high. The check engine light also was blinking. I replaced my water pump about 70K miles ago.

Apparently while I car was at the stealership for it's 45k service, the car alarm was going off crazy and wouldn't stop, so their techs disconnected the horns.
First time they delivered my car back, the horns wouldn't work- sent it back.
Second time around, porter turns off car, closes the driver door, and car alarm starts blaring, other techs and customers starting and closing their ears..
Not sure what could be going on.

Had my car since the end of december 12, now after a drive to San Diego from Las Vegas I experienced a check coolant light beeping this morning. I didn't check the fluids the day of leaving but 3 days before and everything was all good. Checked the levels and it looked like there was barely any in the tank. After I picked up some coolant from the local dealer thinking maybe I just needed to put more in don't know why I didn't have them look at it then I should have. As I unscrewed the cap after letting it sit for a while I saw coolant surface in the tank.
I thought that was weird but I said oh well let me put a bit in since it looked like it was just duno if this will sound right storing more inside the engine? Let it run for a bout 20 mins and took off. from the dealership when I didn't get the warning anymore. went driving for some bit and got the same warning when I was heading back to my hotel. now I was tripping :|. I parked the car and let it sit in a spot with n spots of oil came out and found a decent sized puddle after letting it sit for some minutes. wiped a bit of it up with a paper and it seemed kind of dirty but reddish, and it seemed greasy like.

I am at work and dont have access to my manual. I was driving into work today and the outside temp gauge dropped from 40 to 39 then chimed and flashed as if to say "he it dropped below 40 outside" then it showed a little snowflake picture next to the temp. I have only had the car since summer-so why was it telling me it dropped to 39?

Yesterday when I was coming home my '01 started going on the fritz. The ABS light came on in the console, the Brake light started flashing, and in the onboard computer I received three kinds of messages, "Brake Fault" "Service Manual" and "STOP". What is going on?

Woke up this morning Drop 200 yards before I got a dash notification saying "STOP CHECK COOLANT" Turned off car, turned back on. and noticed never appeared. Showed up to work (temp never went up past half) and check the fluid and its not low. What can cause this.

Stop check coolant light came on dash tonight. Scanned the car no code. Did a search pointed towards coolant temp sensor. Car had it replaced by vw estimate of 30,000 miles ago. I tried to see if its green top sensor appears the very bottom ring is green but top is black maybe vw's is different than ecs? Planning to do water pump, belt kit from ecs anything else i should be looking at?

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?

How does one clear the computer to prevent the display "Check Coolant Additive" from appearing every time I start the truck. I know that a chemical test is needed to determine the status of the coolant.

Why does the trip computer not reset after every stop, and can it be set this way when required. I've read one explanation abut the Phaeton being a "motorway car", so there is period between stops within which the trip computer does not reset -

I have a 2002 passat. it is a v6 with a manual trans (i do not know about gls or anything like that) but the coolant stop light is coming on and if i drive, it runs hotter than normal. i assume it is a thermostat stuck closed but is there anything else i should look at before i make that assumption?

My beloved 2005 Phaeton has started beeping when turned off both with and without the security system engaged. This has never happened before.

When I start up the car in the morning, the infamous "STOP!! CHECK COOLANT LEVEL" warning will come on, and then shortly thereafter it will go away. I topped off the coolant level (with the pink stuff of course) and yet this light will come on occasionally. It mostly comes on first thing in the morning when the car is started up and cold, and *sometimes* come on when the car is warm. Fluid level is all topped off. What gives?
I was reading that there is a fluid level sensor that sometimes goes bad? could this be it? I changed the coolant temp sensor back in the summer of this year. (not sure if that has anything to do with it?) Not sure if I have a leak, cause I look under the car in the morning and I have no spots of coolant anywhere.

I was driving in traffic when the "Check Coolant" message appeared in the MFD. I looked at the coolant temp and it was approaching 280F. I immediately pulled into a shopping mall parking lot and stopped the engine. I popped the hood and saw that the coolant resevoir was full. There was no coolant on the ground but there was a coolant odor. I called for a tow and had the car towed to the VW shop within a mile of where I broke down.
When the tech got to my car, they said that the "computer" pointed them to the fans and their relays/modules (2). They placed an order for these parts. Once they arrived, they installed the new fans and relays but they couldn't get the fans to operate. They subsequently removed these new parts and replaced them with the old parts. They then opened a dialog with VW Tech-Line.
Somehow they discovered that the fuse to the fan modules was blown. This was replaced and the fans began to work. After running a "system scan" it reported a bad ignition switch. This is now on order. My car has been in the shop for almost 2 weeks because of this. What's going on here? Was the fuse the culprit all along? If so would the computer have pointed them to the fuse or would they have had to find it themselves?

Lets start at the beginning. About two weeks ago my girlfriend got a check engine light and the car started missing( 98 Passat 1.8T, 5 speed). Checked obvious things like fuel delivery-good. Pulled coil packs and had no spark on #2 cyl. Investigated more and found one of the pins on the ign. control module was shorted. Felt pretty sure that was the problem since everything else checked out. Ordered a Huco installed it and that fixed the problem except the car seemed slow reprogramming to the new part. I disconnected the battery to clear the memory and that seemed to do the trick.
About 2 weeks later my GF is coming home and fortunately it died in front of the apartment. Checked everything again. Getting fuel, no wires shorted on ign. or fuel harness plus they all get power just no signal when checking with an LED tester. Ign. module was good also. Checked speed sensor for resistance per the book it was good. Tried a new Camshaft Pos. Sensor hoping that was the problem, no luck. I believe it must be the computer. I'm trying to get one from a salvage yard. I don't know if the old computer can be reprogrammed or not. Also was wondering if the dealer(where I really do not want to go) can test the computer somehow and tell me if it is bad or not(don't know if I would trust them anyway), just wanted to include that option.

I posted recently because my '05 Touareg had been in twice for a "coolant overheating" error when the car was driven less than three minutes after a long cold start. They replaced the main computer and I had it back for a week and everything was fine. This morning, the same error occured. We took it in. When my husband drove it to the dealer, the warning went away after several minutes. They said that the error never logged on the computer and there's nothing wrong.
One person had responded last time with the sensor issue but got it resolved. I am really concerned about the possible problem that they can't seem to fix. They seem to be ok with it.

I was cleaning my passat the other day and I took my air filter out, however I didn't disconnect the wires and hoses on top of the box, I just raised the top cover up and pulled the filter out and cleaned it and checked it and put it back in, I also took out the cabin filter out and cleaned it and put it back in too, then I started the car and took it for a ride and the car started over heating, it keeps giving me STOP CHECK COOLANT warning and the temperature rises all the way to max RED.
I check the coolant level is at level and the radiator fans are spinning, however I noticed the lower hose that goes from reservoir to the radiator is cooler than the other hoses, what could be the problem? The water in the reservoir is hot too, could this be from a faulty thermostat? a sensor? or somewhere I read there is a fuse somewhere in the engine bay? I'm not too familiar with these 1.8t engines, the temp sensor was acting funny before too like sometimes it would go all the way to zero and stay there and go up and go down to zero and then raise, which I think there might be a bad connection or bad sensor.
I forgot to add the car is a 2003 1.8T.
