Touareg :: Radiator Fans Stays On After Ignition Shut Off - Kills Battery
Jan 7, 2009
Believe an engine temperature sensor is bad. I took it in to get a code read, and they said it could be either temp sensor or fan switch, but didn't know which one without newer software.
Codes are
19537 - Engine Temperate too Low
P3081 - 008 - Implausible Signal
I've checked the fuse legend to see if there is a fuse I can pull, but none of them marked fan seem to kill it after the car is off, so that I can save some battery power.
I believe that I have narrowed it down to the engine coolant temperature sensor. What is the level of job this is to replace? From a parts location manual, it looks like it is in the Thermostat housing, but I'm not sure where that is.

2011 Santa Fe with a problem with the fan. Believe it's the radiator fan. First time it happened, wife shut off car and fan was still on. Started it back up and shut it off a couple of times and it stayed off. That was over a year ago. Then today, same thing except she didn't notice it until she came back out to car and the battery was totally dead. Got a boost and as soon as they hooked up the leads from good battery the fan was on. I saw someone in a thread about a 2006 Sonata (?) doing this kind of thing.

So my radiator fans were staying on until my battery died and my car was completely cooled down and off. I was told it was a sticking relay so I replaced it and the fans still won't come on. I unplugged the coolant temp sensor and the fans came on so I know its not the motors or anything.

Well I noticed the fans are running at shutdown, then next day check engine light plus the jack light which I was able to turn off. I have had the same symptoms several months ago and they went away. Now its back.

The fans are operating as they should when my 2007 Camry SE V6 engine is running: if AC is off - fans are off too till the coolant temperature raising to the middle of the temp gauge, then fans are started to spin on slow occasionally; when AC is on fans are running all the time. But when I turn off the car fans are running on full speed till battery is dead. What can it be? ECU?

Lately when i take my key out of the ignition, my radio stays on and my car will chime with the door open as if the key was still in the ignition (and it lasts for different periods of time). I also have found it more difficult to get the key in and out. Obviously there is something wrong with the ignition.

Looking at buying this used 2004 F150 and the Seller says it has a problem with the ignition switch; that it continues to run the starter even after the engine is running, which burns out the starter. He's an obvious layperson and doesn't know much about mechanical stuff (or he's pretending, IDK).
This sounds very strange to me, because if it's some kind of mechanical defect/factory defect, it's something that Ford should have identified, documented, issued a recall maybe, or something, yet when I research the issue the only thing I find is a problem with ignition switches that cause fires in model years that end in 2003 (not 2004). Other than that I find no documentation.
I wonder how accurate the Seller's description is, or maybe it's defective due to some other reason, like maybe a car thief shoved something into the ignition and damaged it, or possibly corrosion. Or maybe it's simply "sticky" and some spray lubricant would fix it.

I have a fairly low mileage 2005 Prius I purchased private sale about 6 months ago... so still getting used to a few things. The previous owners had to replace the hybrid battery at about 45,000 mi. From what I understand, that's pretty unheard of. The reason that was given that the battery died was that the Prius was in their garage un-driven for a couple weeks while they were on vacation and the car had been pinging the key fob (close by in the house) the whole time. The associated details were a little fuzzy, but the owner has a note written in the manual about a certain combo of buttons to hit if you'll be away from the car for awhile, but the fob will still be physically close to the car. This combo turns off the hybrid battery (??)
Ok, so my question... How common is this? How long is 'long' that I should be concerned about leaving the car? Is it really best practice to keep your keep fob more than so-many feet from the car to reduce the chance of this happening?

When I start engine usually your dashboard light turn on, eng, seatbelts, etc. but that doesn't happens, but engines starts for awhile and than you see the volt indicator drawing negative. And after few minutes of running it dies and will not start, battery is dead, I believe there is a short circuit or a relay problem....

As it was such a matter of time, my fans on my 24v gave up during winter, no big deal as it was a pretty cold winter but now that spring is around the corner, I gotta fix this issue. To they change for the same OEM unit that will die in the next 30k miles.

First summer with 2014 Passat. We have been getting close to 90 degree days this early in Summer and I have noticed a sensation that I have not had with almost the first year of ownership.
The last couple of days in stop and go traffic I have noticed that when the Radiator Fans edge up to the fastest cooling speed I can feel a vibration in the steering wheel. It is a strong vibration feeling. I had a friend turn off the car while the fans were going full speed. The largest fan on the drivers side seems to wobble as it cost down from the high speed. I am wondering if these fans can be balanced with counter weights.

So this seems to be a common code that is thrown when you near 100k miles, I'm at 77k .. This thread seems to be the most organized [URL] ....
"Long story short, there are 5 main reasons this problem can pop up, listed in order of likelihood, least to greatest:
1) Coolant sensor
2) Thermostat
3) Bad fans
4) Coolant mixture
5) Water pump "
My issue is that the only ones I'm (probably) able to rule out is coolant mixture and bad fans. My radiator fans do turn on from time to time, so I thought I'd ruled that out (unless it would throw a code for not turning on at appropriate times?)
I heard of a test to turn on your AC and see if they turn on, but my AC hasn't blown cold air like ever, so I don't know if that affects the test (probably not?)
A couple years ago I had a shop replace the original thermostat with the new one, or was it the coolant sensor, or both (ugh, I don't remember!) That leaves thermostat, coolant sensor, and water pump.
I guess my main question is is there anyway to find out which it is between these 3, without spending so time, money, parts etc? It doesn't seem the coolant sensor is easily accessible for one.
My car has been really slow recently but I also need to change the spark plugs, I'm doing that this week. I cleared the CEL/P2181 code and it returned a few weeks later,
I'm starting to change my mind about this car being easy to maintain/reliable, I'm always on time with maintenance and with only 77k miles on a 2004 car.

I bought my car last May and never noticed the radiator fans running, but over the past couple of months they've been coming on (or at least running at a higher speed) pretty much every time I take it for a longer drive. They appear to come on only when I'm idling and turn off when I start moving again. The temperature gauge is steady at just below halfway. I'm certain this didn't happen previously, or if it did the fans were at a low enough speed that I didn't hear them. In my inexperience I would have thought they'd be less likely to run in the winter, and we've been having continuously cold weather (<30 C).

I don't understand what is going on I noticed smoke coming from my fans radiator fans and I'm pretty sure that it was motor being fried I've gone to the junkyard and bought a used assembly hooked it up and still nothing could be a possibility that when the motor fried it fried the control module for the fans

I own a 2006 Prius with 52k miles on it. Great car BTW. The problem is simple, the radiator cooling fans stopped working on high mode; they run around 25% only even, not removing the heat from the a/c evaporator and the radiator coolant. I checked fuses: OK, checked relays: OK. They spin freely and nothing is blocking the front face of the evaporator. Funny I noticed it when I started hearing the a/c compressor buzzing noise and then I realized the fan noise wasn't there!

A few days ago I was driving around. I get back in my car and when i turn it on no air blows and the radiator fans aren't working at all. My car hasn't overheated but have stopped driving until I can figure the issue out. I have since replaced the fuse box on top of the battery to no avail. I was thinking that it could possibly be the fan control module but in all the posts I am reading not one says that theirs don't work, they just keep running. So is there something else i should be looking at?
