Touareg :: Insufficient Coolant Warning Light?
Nov 23, 2003
Just over 2000 miles on trex and i just got an "insufficient coolant" warning light this evening. the car had been idle for 2 days or so (i.e. cold start) and the warning light came on. I was running a short errand -- and when i re-started the car to come home, the warning did not come up. A couple of questions...
1) I checked the floor of my garage; I'm not leaking fluid. how could this have happened?
2) If the light didn't come on during the return trip, is everything ok?
3) Checking the manual, it says that i must use a specific type of coolant if I'm going to top it off myself --

I have a VW Touareg 2003. The coolant warning light on the dash keeps coming on and is using 5lts of coolant for every 3 tanks of fuel. Also the oil light has also started coming on. I have had a look around the engine and underneath on the road and have found no signs of leaking. Where the coolant and oil are disappearing to.

While the dealer was diagnosing my low-oil-pressure warning light issue, they found out that there is a minor leakage around the thermostat housing (So minor that no trace of coolant had found its way to my garage floor). They recommended to have the housing and thermostat replaced. They said that the engine needs to be dropped in order for them to get to the thermostat which is facing the firewall. Now, that's bad packaging.

I was towing an enclosed trailer (4000lbs) this past weekend on the interstate and the low coolant warning came on. I pulled in at the next exit at a truck stop to look for distilled water and they did not have any. I decided to buy an off brand long life premixed coolant, pink in color and topped off the overflow tank with about 1/2 gallon of coolant. After reading about not mixing coolants with the G12 that comes in the Touareg, will I have to drain the entire cooling system and refill with G12? or is this not enough to worry about? Should I get the dealer to do this for free since they just serviced my truck prior to my trip and I told them I was going to be towing and to make sure everything is okay?

I had my touareg used for almost three years and never added any coolant. Today was first time I saw coolant warning on dash. I tuned off car and restarted and it was gone.

2001 Santa Fe, 2.4L DOHC engine, 129,000 miles
I bought the vehicle knowing that it was not running well. It idled quite smoothly but had no power on acceleration but was able drive it home at ~30mph. Never had a timing belt change so I foolishly fixed that before I solved the low power problem. Timing belt change went OK and then I discovered the exhaust manifold was cracked - HUGE crack. Fixed that and installed new cat at the same time. Checked compression and read consistent 127-129 across 4 cylinders. Also installed new before and after O2 sensors at this time. Started her up and sounds good, idles smooth. Hooked the scanner up and read P0115 (something about engine coolant temperature circuit), so I cleared it thinking it must have overheated in the past and that is how the E-manifold cracked.
P0115 never returned.
I have no codes showing now however it appears to be running in open loop and scanner shows "open loop due to insufficient engine temperature" but engine temperature is reading 200 deg F. Also the O2 sensors are not being read, see attached readout.
At this point I am stumped and am thinking I need to check fuel pressure or maybe injectors are clogged. But why would it be running in open loop?

About a month ago I noticed the coolant level looked a little low. I attributed it to the fact that the engine was warm after driving. Tonight the coolant light illuminated and the mfd states the level is low. Sure enough it's quite low.Is this normal for the R? I know my MK5 GTI burned oil like crazy. Should I be concerned?

Had my low coolant warning light and message come on while driving home from work. My car is 1 year old with 30k on it, motor is hot right now and coolant is a good bit below the minimum line (will post a pic soon). I do my service intervals at 7500 miles at most and regularly keep an eye on my oil and coolant levels.
I just checked the coolant last week after an oil change and noticed it was at the bottom minimum line, it's fairly below that now. Does this call for a ride to the dealership? I've seen where people have had pumps/hoses replaced already due to leaks. Nothing on the ground from what I can tell and nothing seems to be leaking under the hood.

Picked up a 2013 Touareg in May. Traded in a 2010 GTI.
Had the low coolant light go on. Checked the coolant levels and it was below the minimum. Went to the dealer and filled the reservoir. Haven't had an issue or notice any leaking coolant since that day.
Seemingly came out of nowhere and hasn't appeared since. I don't believe I have a leak in the system, but haven't had a chance to bring it to the dealership yet.

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..

Just bought a 2002 Prius for my daughter at an auction and the car has been driving fine the last few days even though the hybrid warning light has been on and off. Found no fault code with OBDII. Found out later from Toyota service history the cause of the hybrid warning light was a leaked hybrid battery. The previous owner disposed the car off at the auction before the problem was fixed.
I was driving today and the coolant high temperature came on and I can't rev/drive. Stopped engine and re-start after a while and coolant high temperature warning light gone. Drove a short distance and coolant high temperature warning light came back on. Used a OBDII and found no fault code. Radiator hose by the radiator cap is cold but hose at the top right side of radiator by the hybrid system is hot. Opened radiator cap and it is full of coolant.
The car has been serviced on 12/26/2012 before it went to the auction. Can air pocket trapped in the radiator cause this coolant high temperature warning light and can't rev/drive problem. Also today is the first time we didn't use the heater. We used the heater to defog the windscreen and heater work.

After about an hour of driving, the coolant temperature light on my 2010 GTI started blinking. The gauge never showed a temperature higher than the usual 190, including traffic and idling. Having reached my destination, I shut the car off and then back on, happy to see no warning lights at all. One dinner and some three hours later, I started back for home. 20 minutes into the drive, the car sounded three tones and the blinking light came on again.
Like before, the car drove without incident for the rest of the drive, and the light was no longer present once the car had been shut off and then on again. The owner's manual said that the coolant level might be too low, or the temperature too high, but neither of these seem to be the case. The car is equipped with GIAC stage I software and an Audi S3 intercooler.

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.

Could there be something else going on, or should I really expect to have to replace the pads at 19,000 miles??

So over the past few weeks I've grown accustom to my airbag warning sensor and light on, a lot.
First time two weeks ago - Airbag light came on, brought it in...Repaired wiring harness reset light. Light comes on next day, make an appt.
Second time today, brought it in...Just picked it up, fired up the Treg airbag light comes right back on. I was told another harness was repaired and something about a side airbag firing something...
So my third time is in the next week or two... fab. They say the whole harness is to be replaced, which is cool. I respect my service team, the engineers as well... I'm going with the flo, I'm pretty laid back.
My questions is...How long do I need to go with the flow if this keeps happening? All the while this is going on, for every issue I have that's super legit airbag, stepper, running gear. They keep giving me the hook up on, new wood trim, new headlight switch, new mirror switch, new buttons on my center console, new buttons on the nav....

This light went on after i was about 1/2 way though a tank of gas. After i refilled it the sensor went off. This occurred on and off for about 2 weeks. Now the light has stayed on for a few days, than turned off for a few hours. Well now its back on again, any issues with this sensor? I think its just the sensor and hope its not something major. It stays light the entire time and does not flash.

While driving this morning and entering the highway, the light with the triangle came on, I stoped the car right away. Check engine oil levels and turn car back on. Now engine light and warning light stay on, all temp and pressures ok.
Drove to the dealer car feel fine but the screen does not show the gear you are on while driving, blank.

No major problem, just had the warning appear but lights seemed to work normally. I could reproduce the problem once and then it stopped. What is the cause/solution identified by VW?
