Passat (B6) :: Code P2181 - Cooling System Performance
Mar 18, 2013
Have an '07 2.0T w/92K on it. Check eng light came on over the weekend. Performance is fine etc. Went to AutoZone just to find the general area of the the trouble code since there's no one with a VAG Com nearby. The code is as the title indicates. For the last 5 months the temp gauge has been moving 1-2 ticks to the left (cooler) of the normal 200 degrees, then it will go back to 200 etc. It previously has always stayed on 200 once it warmed up. Does this sound like a thermostat?
If it is, I'm wondering if I could save some money while they were in there to go ahead and change the TB as well? From what I've researched the thermostat is in same area. I was planning on doing the TB at around 100-110k so while it would be earlier than planned I'd do it if it meant saving a bit from the combo work.

Last night on my way to go get hammered the check engine light popped on...
"Cooling System Performance"
I have read a few different post, and the last one I read referred to his radiator fans. I know for a fact one of them isn't working and I haven't replaced it yet because it hasn't advisable effected my driving.
So my question is what could be causing this? Also I'm not sure if this matters but my a/c doesn't work either.

The code in question is:
18613 - Performance Malfunction in Cooling System
P2181 - 008 - Implausible Signal - MIL ON
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
It's a fun catch-all code that can be thrown from any of those. Given that our cars are approaching the 6 year mark, the coolant sensor & thermostat are the most likely culprits. Most of us up on maintenance have already done the green-top sensor, so it's probably the thermostat. In which case, here is the official changing the thermostat DIY: [URL] .....
If you get this code, first check your fans. They're running? Okay, change your sensor & clear it. If it comes back, change the thermostat. If it still comes back, which has been known to happen, investigate further. [IMG] [URL] .....

I've recently started popping up a random P2181 performance malfunction in cooling system.
It's so random and shows no signs of any other problems that I'm confused. Temp gets hot, stays exactly where it should be, 200. Never gets a tick hotter, or even close to above 200. Air works, heat works fine. No loss of power. It only seems to come on when I really put my foot down.

Like the title states, I've got P2181 (coolant system performance) CEL on again. I've had this code before and finally had everything serviced. It was off for 5k miles! I've spent a lot of time diagnosing this on the previous occurrences, and was 99% certain it was the thermostat due to the coolant temp dropping a notch or so when engine braking* on the interstate for more than a few seconds.
The current issue is mainly that the car will not heat up quite as fast, but it will not go lower from engine braking for a good chunk of time. I'm getting fairly poor MPG compared to what I was getting a month or two ago. The major changes are winter fuel blends and winter tires, which I'm sure affect the MPG a little, but I would hope not as much as I am seeing. Old average was around 27mpg combined and 30 or so for mostly highway, now I'm getting 24 tops. This is likely due to engine temps not being up to allow for most efficient fuel burning.
First plan is to change the CTS and see if that will fix it. If the code comes back after that, I'll have to check the thermostat and coolant mixture, but I wouldn't expect it to last only 5k miles.
Current: 105k
Thermostat and coolant changed at 100k
Water pump at 80k
CTS sometime around 70k
Engine braking lowering temp due to no fuel being ignited and coolant still circulating through the system if thermostat open.

I have a 2007 Prius, and bought it used about 4 months ago. I have not had any issues with it until last night. Last night I was driving home and the red triangle with the “ ! “ in the middle and check engine light came on. The car seems to be running fine, but it scared me to see the lights come on...so this morning I called my local Toyota dealership.
NOTE: I recently went to them for an oil change and they informed me that I had three recalls on my vehicle that needed replacing, but I did not get them replaced because I was told it would take 5-6 hrs (which I didn’t have at the time).
Anyway, they told me that it would cost $70 to have the codes read...and that did not include parts that may need replaced... I thought that sounded a little high for just having the codes read so I went to my local Autozone and they gave me this code:
P0A93 - Inverter Cooling System Performance

If I am not mistaken this error code means that I have a coolant system issue. I've checked both of my radiator fans and they both spin, so it makes me think that its the thermostat issue. If I am correct, any link to a replacement part? Or better yet a DIY? I've searched and no dice.

So i got a cooling system performance light and haven't had time to change the sensor out along with the housing... But
Last night i was stopped to see if it was still there after a little driving and it was indeed. So i figured i would try and clear the code to see if that work and it did. I cleared the code and almost instantly with the car still idling, the ticking sound went away.
What could have cause the ticking sounds at all in relation to the cooling system?

So after 1.5 years of owning my R I got my first CEL. The code is P2181. I did some searching and this is a problem in the coolant system.
In the previous posts about this these were the possible problems:
1) Coolant sensor
2) Thermostat
3) Bad fans
4) Coolant mixture
5) Water pump
I checked my car and I have the updated green coolant sensor. My question is should I just get a thermostat and replace that or should I replace the green coolant sensor with another one? Do the green ones go bad?

I am getting to check engine codes and I can't figure out what is causing them, one is P1296 cooling system malfunction, the other is P1654 Check DTC Memory of control panel ECU, any clues as to why I'm getting these, I did have a bad thermostat i changed that and it's still on, I also used the new prestone antifreeze for all makes and models, cause I am about 200 miles away from a dealership for g12.

I have a 2004 Saturn VUE, 3.5 L, V6 (212 CI), AWD, with 164,000 miles that I purchased used in Michigan from a GM Dealer about a year back.
The air condition on this VUE works great as long as the vehicle is moving on the road. When in idle and parked, the cooling performance appear to get reduced and soon it will blow not so cold air until the vehicle start to move and gradually the performance will get better and perform well. How did you get it resolved?

So CEL came on a few weeks ago as it does here and there so got it scanned today and it said "cooling system too lean" could it just be the mods throwing the light. car is tuned so i thought cel wasn't suppose to come on and no mods to the cooling system beside cold air intake..

My MIL came on the other night so I brought it to the dealer today for diagnosis.
Per tech, "Found 1 DTC P2181 for cooling system malfunction, checked measuring values, found thermostat sticking open.
Recommendation is to replace thermostat with housing." I have 95K miles on the car, original owner...first time in a long time to have an issue.
The SA indicated the thermostat replacement. The tech indicated the thermostat is in the front of the engine which is hard to access.

Planning on doing a flush, but how do i bleed the air in the system after? is there a bleed bolt?

Was just mulling over redoing part of the exhaust system on my truck. As it stands the original y-pipe is still intact but some bozo reduced the rest of the system down to 2.25 inch with an ancient glasspack for a muffler. Maybe he thought it would net some kind of benefit, maybe he was just throwing together parts from his backyard. Either way it's going, I'm planning to keep the Y-pipe but step it up to 3 inch with a Flowmaster chambered muffler and I just suddenly wondered if the position of the muffler in the system affects performance. If I put it directly after the Y-pipe the exhaust pulses would hit it sooner...

Sunday I received the dreaded DEF system fault message on my 2012 CC SRW SB FX4 with 7800 miles on it. Warned me that speed will be reduced to 50 MPH in 50 miles. I have a CTS Insight, so I checked for DTC's. First one was P2200 - NOx sensor circuit (Bank 1, Sensor 1), the second one was P204F - Reductant system performance (Bank 1).
After 50 miles it warned me that speed would be reduced to 50 MPH on next restart. Sure enough, Monday morning speed was limited to 50. I took it to the dealer, but I should have left it running. When the service guy started it, the fault had cleared and it no longer showed the P2200 NOx sensor code, although the P204f code was still there.
My question is, why in the world would Ford make it so that the code is cleared if the fault goes away, especially after putting you through the 50 MPH limit scenario?
Dealer did a reflash and said its OK now, but I'm not so sure. My trucks build date is 10/6/11. I read TSB 11-11-13 which states the NOx sensor module should be replaced for P2200 on trucks built before 10/11/11. Is that only for a persistent P2200?

I have a 1997 no turbo Passat 2.0 6 cyl.Over the weekend one of the plastic pipes for the coolant system cracked and after the replacement I end up with the panel telling me that there is no coolant on the reservoir. How to bleed the air out of the system or if there is any bleeding valve for this purpose? And where is located?

The MIL came on and I scanned for codes. First was P0118, Engine Coolant Temp Circuit High Input. Reset it and then received P1296 -Cooling System Malfunction. Temp gauge needle is positioned where it always is.
