Passat (B6) :: Cold Weather And Using Heater Causing Engine Temp To Drop
Nov 18, 2012
the car 07 passat wagon fsi auto value edition.. This is my first winter in Maine and I've noticed by 35 degrees F and colder when vehicle is at operating temp and then I use the cabin blower say 72 degrees or hotter on fan speed 2; causes engine temp to drop maybe 10-15 degrees. Car reaches operating temp quickly! And coolant concentration seems right!

I have a 2000 Corolla CE with 51k miles (bought a couple of months ago).
It ran perfectly during the hot weather (75-80F) and it idles around 650rpm-670rpm. These couple of weeks, there have been very cold weather (60-70F) and it idles mostly around 650rpm but can drop to 630-640rpm. Sometimes, it will suddenly drop to around 612rpm (there will be a very slight shudder) and pick back up to 630rpm. This is with all accessories turned off.
If I turn on the windshield wiper, then every time it activates, it drops to around 612rpm and picks back up quickly. This only happens during cold weather.
I don't think it's the MAF sensor.. what it could be?

First off let me say I love my TDi for everything I bought it for...fuel economy, space, ride comfort.
I've noticed the wind noise before but had never taken a drive more than 30 minutes.I just took my first 300 mile road trip and REALLY noticed the EXCESSIVE wind noise.
I traded a 2010 GTI and its weather stripping was more full and produced a much better closed door seal and I never once had problems with wind noise in the 2 years that I owned.

Well, as the cold weather has approached, a minor issue has surfaced.
It appears my driver-side mirror heater is not working. Both mirrors still move as they should, and the rear defroster and passenger side mirror both heat as the should with the defrost button, but the driver side does not, as it is cold to the touch and naturally did not melt the frost yesterday.
I looked at the fuses hoping it would be something as simple as that, but it does not appear there are separate fuses for each mirror; the naming is a bit cryptic, but it looks like there may be one for both mirrors, which logically would not explain the situation.
Seems to me the heater itself is defective, and I am not exactly looking forward to opening up the mirror and/or spending money to fix this...
The Prius is a 2006, and I am up to 256K KM (~160K miles) to date.

Above 0 Cel.(32F.) 145 F-165 F. even in summer towing. Winter when it gets -20 my trans temp gets warmer (not towing 165.F or higher) When it gets to -30 my trans temp gets to 175 F. or higher I have never looked at trans temps before on any vehicle that I have owned. I like that these trans get warmer when it is cold out and colder when it is hot out.

My Jetta runs great in the summer and all seasons around town... the temp stays around 195 or so, the heater works ok, etc. When I get on the interstate however (now that the temp has dropped) , the story changes. The temp gauge falls below 150 and the heater gets cold. I assumed the thermostat was stuck open, so I replaced it but it didn't solve the problem. I called a local dealer and on his recommendation, I replaced the Engine Coolant Temperature (ECT) Sensor. That also didn't solve the problem. I have had cars overheat in the past, but never one that overcooled! Wy my car cools too well at highway spheeds? It affects my gas mileage and makes for an uncomfortable ride on cold days!

I have a 1991 Silverado C1500 and when I push the heater button to on, the thing just goes absolutely crazy. Instead of one little indicator light, that is suppose to show hot, it lights up all the way across, like a pinball machine that has tilted. The heater air does not get hot and the temp indicator on the dash (separate guage) will not move off of cold. I am going to replace the thermostat, but what is going on with the darn temp gauge?

Tonite on the drive home it was about 10 F and once my car was up to temp, I put my foot into it, I felt the car hesitate a bit, the CEL flashed a few times and went off. Could the cold temp cause that or is it more likely a bad coil?

I have a 99 B5 and the lights for the Heater Temp Knob, the AC/ heater Fan Knob and the blower direction knob are all out. The fuses are OK. I have checked that.

So this is weird. When it is cold outside it takes a few minutes before my stereo will work. It powers on and you get a quick blip of audio but then it takes a few minutes before it will work again. What is causing this issue?

2004 Passat 1.8t that is intermittently not starting. The problem only happens when the car is cold. When I turn the key, the car cranks just fine but will not start. All of the dash lights light up and I had the battery tested and it is fine. Tonight it took about 5 minutes of repeated cranking and waiting before the car started.
After a 15-minute trip home and it had a chance to warm up, the car starts just fine. I've taken it to my mechanic but they haven't been able to replicate the problem. I'm thinking about leaving it overnight just so they'll be able to replicate it.
Not sure if it could be related, but I just had a coil replaced a few weeks ago (the coil was <1 year old). The plugs are only 3 months old.

I have a 2002 VW Passat wagon. We have had an extremely cold winter here in New England (coldest January since 1898!). Anytime the temperature goes under 10 degrees overnight, my brakes do not work in the morning. When I put my foot on the brake pedal, it does not move and the car will not stop. It takes quite a while before I have full breaking capacity restored. Eventually, it gets back to normal (sometimes takes 45 minutes of driving). In addition, the last time this happened, before I got full braking back, my front brakes locked up and smoked like crazy. When I put my foot on the gas, they disengaged. I've taken the car in for service, left it with the dealer the night before so that it would be there, cold, in the morning, but the problem didn't occur because the temp didn't get cold enough. They couldn't find anything wrong. That's because the brakes work fine when the temp is above 10 degrees. Also, under the same temperature conditions, my automatic transmission will not shift beyond 2nd gear until the car is warmed up.

Cold start issues that my 2006 2.0T Passat is having. A few weeks ago, during a stretch of cold weather (10-20F), my Passat would sputter when I tried starting it up. It would either start and immediately shut off, would attempt to turn over, and generally on the 3rd attempt would turn over and run fine. I was only having this issue in the morning, and it would start fine when I would leave work (9 hour shifts).
I got my battery tested, and it proved to be failing. Replaced it. A few days later cylinder 4 started to misfire. I replaced all spark plugs and coil packs (85k on the car). During this service discovered that my oil had gotten some moisture in it and have off-white residue, flushed oil, replaced with new filter. A few days go by and I get code P2181 (cooling system performance). I cleared this out earlier today and it hasn't come back (50 miles later).
Are things just starting to go at the same time, or might there be another underlying issue? I have plans to flush the tranny and do the timing belt/coolant/water pump in the next month.

My 2006 passat trunk is not closing in cold weather. Even if it stays the alarm beep will not come on indicating it is not closed. If I let it sit under the sun (or warm garage), it will lock.

I can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.

My 2001 L.L.Bean Edition H6-3.0 is losing power & MPG on the fwy. Sometimes it will feel like something is holding it back or dragging. I've checked the brake calipers and they're not sticking, changed the air filter, oil & filter, transmission fluid, and still cannot find the problem. I've overfilled the gas tank and read this can damage the charcoal canister. Will a saturated charcoal canister cause a drop in power and MPG? What should I check out next?

I was heading home last night from work and noticed something odd. It was the first pretty cold night that we have had around 20-25 deg. and I took off from the parking lot like normal.
When I got to the first stop light about a mile down the road I heard what sounded like the engine revving up right when I took my foot off the gas pedal. It did this as I coasted to the stop light. It also did it again at the next stop light just up the street. I thought maybe it was the heater blower, but It really sounded and felt like the engine revving. The car did not accelerate or anything, is this part of the warm up or normal? I also have the lower grill blocked but I don't see how that would make any difference.

Went on a trip up to MI in cold and snow, and the engine light comes on. Great, I'm thinking, figuring me, the wife and our two babies stranded in another quality VW product. We pull over and call the closest dealer on the cell, and they say to just ignore it unless its flashing. When I got home, I vagged it and it says the cats were below their operational limit - I'm guessing too cold?
Whats the deal here? Can I look forward to engine lights everytime I go out in the cold? (this car is slowly driving me nuts. How can it be so bad and my Audi so good?)

Does the prius c heater work if we set inside temp higher than outside temp ?(Difference is 2 or 3 degrees ). Is the heater take more energy than AC ?
