Passat (B5) :: Engine Temperature Gauge Did Not Seem To Be Functioning

Recently (3 months ago) I had the timing belt, thermostat , water pump changed . Just yesterday I noticed that the engine temperature gauge was all the way to the left and did not seem to be functioning. I do not know if it had been like this for the 3 months since the maintenance work....maybe not. But, the guage is not working.

Passat (B7) :: 2012 / 2.0 TDI Engine Temperature Too Low - Gauge Will Go Up And Down

I have a 2012 Passat 2.0 TDI (140) DSG

Sometimes the engine temperature stays low for an entire drive. Regardless of speed - it has happened while sitting in traffic for hours or while sitting at 70mph.

When this is happening, the engine temperature gauge will go up and down, but never reach 90, and the oil temperature reading fluctuates from around 60 to 80. Also the air into the car doesn't get hot enough, but now we're out of winter that doesn't matter too much.

But then other days it will be 100% fine - it rises up to 90 within 10 minutes of a cold start and stays there the whole day - and the oil temperature sits between 90 and 100.

I've taken it to a couple of VW dealers but obviously it behaves perfectly on those days! I remember reading something about a thermostat that circulates coolant to the DSG box, which can cause these kinds of symptoms?

Passat (B5) :: 2004 - Temperature Gauge Seems To Bounce Up And Down A Bit

I just picked up a 2004 1.8T 5 speed 4 motion. It drives well, however i noticed some bugs. For one, the temperature gauge seems to bounce up and down a bit. I check the vag, and the car never gets abobe 75c, and usually sits around 70c when im cruising on the highway. So i changed the green top sensor to start, and I think it may be wrong, cause now the engine fan always stays on, and the temp problem is still there. SO now I have this fan issue, and still a temp problem. Did I change the wrong sensor totally? Is it my thermostat?

Passat (B6) :: Temperature Gauge Fluctuation While Coasting Downhill?

Typically after driving for 5 minutes or so my temp gauge is in the middle at 200f. After about 15 min of moderate 35-45 mph driving it went down a notch below the 200 mark after it had reached 200f. I've noticed this happen a few times recently. I did notice that it happens while coasting downhill. I guess i'll be taking it it to my mechanic to take a look.

Passat (B5) :: V6 Rough Idles After Temperature Gauge Fixed

02 Passat 4Motion with the 3.0L V6. I just had the car at the dealer 2 weeks ago for the 50K service and to have the temperature gauge fixed. Otherwise, the car was running just fine. At the service, they replaced the water temp sensor, performed a fuel injector service and radiator flush (both recommended).

Now two weeks later, her car rough idles, dies and has to be towed to the same dealership. They first diagnose fouled plugs which they replace gratis. They then tell me the plugs fouled because the ignition coil and wires have gone bad and need to be replaced. They want to do an additional injector/intake cleaning service. They are offering to discount the services slightly. I'm still going to be out another $850.
I called Volkswagen Customer Service and they confirmed that the ignition coils were not covered under the recall.

Something sounds "off" to me. The car was running fine before the initial service. Was the dealer just being "nice" in comparing the plug replacement or did he think that they initial fuel injector service may have fouled the plugs? I don't really want to pay 2x for the same service and now the coil/wire replacement.

Passat (B5) :: Temperature Gauge Registers Far Left At All Times

For the past two days, the coolant temperature gauge has registered cold (far left) all of the time. Just the day before, it registered about center when the engine warmed up, it's typical location.

The vehicle seems to run just fine, and the coolant level looks good. Is it safe to drive it to a shop (~35 miles) to be fixed?

Passat (B5) :: Engine Temperature Gauge Reading 190 Normally And Then Suddenly Drop To Almost 0

I have a 2003 Passat and the engine temperature gauge will read 190 normally and then suddenly drop to almost zero, stay there for a while then head back up.

I purchased a temp sensor to replace the old but for the life of me I can seem to locate it. I know it's in the back or rear of the engine somewhere.

BTW, the car has the 1.8 engine.

Passat (B5) :: Temperature Gauge Needle Will Randomly Drop On Dash Cluster

Last fall I had my radiator flushed and at the same time my coolant overfill canister with built in temperature guage sensor was replaced with a new unit. (The service station replaced the resevoir canister with a new unit in the engine compartment, because they felt the sensor is prone to failing after 7 years.)

Ever since, my temperature gauge needle on the dash will randomly drop (even when the car is up to FULL OPERATING TEMPERATURES) showing the engine being cooler than it out to be. In other words the needle drops signifying to a much lower water temperature. After a period of time the needle will recover back to the normal full operating temperature mark on the dash gauge.

What could cause this? Inside my radiator do I have a "diafram" temperature valve that could be failing /"sticking?" In other words could a temperature valve in the radiator be sticking at odd or random times??? I also notice that my heater does not put out the usual full furnace heat that a Passat is know for. The temperature is about 1/3 cooler now that we are into winter temperatures.
Is my heater core clogged?

Could the new coolant sensor in the new coolant overfill chamber not be working well? This whole situation began AFTER my radiator was flushed, and AFTER I had the coolant reservoir canister and sensor replaced.

Passat (B5) :: 1999 - Coolant Temperature Gauge Reaches At 190 Within 5 Minutes And Stays?

I have a '99 1.8T Passat. The coolant temperature gauge normally reaches operating temperature of 190 degrees within about 5 minutes and stays there. For some reason, after reaching 190, it sometimes drops by 20-30 degrees and is running cooler than normal. Once time it dropped down, then came back up again, while driving a steady 65 mph. The coolant level is full and nothing else has changed.

I guess there are a few possibilities: a thermostat stuck open too far, a failing temperature sensor, bad gauge, or loose connection at the sensor. The car has 145K miles and the thermostat and water pump were replaced at about 100K miles. What is going on? If it runs a little too cool, is that a big deal? How would I diagnose it? Where is the temperature sensor?

Ford Super Duty (1999-2016) :: Temperature Gauge Pegs And Dinger Goes Off - Check Gauge Light On?

Just about every trip i take my temp gauge pegs and dinger goes off and check gauges lights up in the message center. It eventually will go back to normal or if i shut key off and restart truck it goes to normal. im guessing it is the temperature sensor for the gauge but not sure?? If it is, where is the gauge sensor located?

Golf IV R32 :: Temperature Gauge Fluctuation

So my temperature gauge started fluctuating from low to mid-gauge reading and it does not matter if at idle or driving. It never goes above mid-range or reads hot. I have had my diagnostic tool connected while monitoring the ECT in real time and my temp reads 180-195. Also there are no codes and everything else is running normal.

I have searched other threads and the only thing that was mentioned was changing the temp sensor but they also had the issue where the diagnostic tool also showed the temp fluctuating.

Mazda :: Temperature Gauge On Dashboard Moves Very Little

1996 Mazda Protege, 125,000 miles. Temperature gauge on dashboard moves very little.

Do I need to get this checked out, ie, if not what would happen? (I have had car in recently for other problems but no one n the shop mentioned it, even though they have had the car out for a drive).

Golf/GTI VI :: Temperature Gauge Go Up Into The Warning Zone

I JUST got my brand new 2011 gti this wednesday, which I am obsessed with. When I was driving around earlier yesterday however, the temperature gauge started to go up and into the warning zone. a message on the dashboard then sed "check engine coolant see manual".

So i did, and according to the manual everything should be running perfectly fine. So i pulled over till the engine cooled down to normal, then after about a mile it happened again, and it kept overheating every mile. I got the car towed by vw to a dealership nearby, but they're closed on sundays so i have to wait till tomorrow.

Prius (2004-09) :: Outside Temperature Gauge Fluctuates

Something strange started happening to my '04 Prius yesterday and it happened again today. We are experiencing unseasonably warm temperatures here in Western Oregon for October and when I left my house this morning at 6:30 am, it was about 55 degrees. I have a half hour drive to work on a mixture of expressway, freeway, expressway again and then the two-lane highway.

Anyway, yesterday (and today) when I'm almost to work, my temp. gauge drops down to 37 degrees. This causes that yellow light to start blinking indicating that the engine will not shut off because of cold temps. It will warm back up to 45 degrees a minute or two later. Why is this happening? It for sure is not 37 degrees outside. Is my temperature sensor going bad? Is this exhibiting the behavior of a sensor going bad?

Lexus RX 2004-09 :: 2007 - Sluggish Outside Temperature Gauge

When taking our 2007 RX out of say a 72 degree garage to say a 90 degree day, it takes at least 10 minutes for the outside temp gauge to finally creep up to the ambient temperature. The gauge feels very sluggish at all other times.

Accord :: 93 EX Sedan - Temperature Gauge Reading Cold

I have a 93 accord ex sedan, 4 cylinder, automatic that I bought in August. I live in South Dakota & it's starting to get cold here. When I first bought the car the temp gauge was working fine in that it would move to the middle of hot/cold range. Recently, I've noticed the interior doesn't get warm for awhile, even after driving 20 miles. It blows warm air but it seems like it should be warmer. I've also noticed the temperature gauge barely moves, if it does at all. Most of the time it doesn't move or just stays on cold. I did some research on here & thought I would try to change the thermostat, upper & lower hose and the antifreeze. I'm hoping this will heat up the interior better because it's starting to get cold here & fix the temp gauge.

Previously, I had a 91 accord & that would warm up great, even when it was bitterly cold here. What would cause the temp gauge to do this? I'm even thinking about changing the transmission control module because I read on here that could cause the gauges to have wrong readings. The speedo & rpm gauges also seem to have wrong readings, especially in the mornings or when I first drive it. I used my gps & found the speedo to be off by as much as 10 mph. The other item I've noticed is that I only get around 23-25 mpg highway & on my other accord I was averaging 28-30 mpg highway. Not sure if this is related or not but thought the more info the better.

I have done all the basic maintenance-oil & filter, plugs & wires, valve cover gasket, air filter, tranny fluid but have never done anything with the heating/cooling system.

Sierra :: Temperature Gauge Running Low / Reading Cold

Tempature gauge on my 2001 sierra (4.8) has been running low for awhile. The highest it will reach is round 160. It's currently running rough/rich and bad mpg. I replaced the ECT sensor but didn't work. I'm not sure if there are two ECT sensors on this model. I don't think it's the cluster. Is there a second sensor I'm overlooking?

Nissan - Sentra :: 2002 - No Heat And Temperature Gauge Going Up And Down

I have a 2002 Nissan Sentra. In Nov. 2010 had inspection done and replaced upper radiator hose at that time. Right after that, I had no heat and the temperature gauge would go up to hot but then come right back down. Brought it back to mechanic, changed thermostat and both things ok only part way home. Started riding with coworker only driving to her house 7 miles away and still temperature gauge up and down, stopped driving completely in Feb. Just brought it to dealer who replaced thermostat and worked fine all the way home and then started all over again the next day. Seems to happen faster at higher speed but will eventually do it in any driving conditions. Today service engine soon light came on. Obviously not thermostat problem. Could it be water pump? Dealer did pressure test and that came back fine so no head gasket problem although don't have a lot of faith in that since problem still exists and they thought thermostat would fix it.
