Passat (B6) :: Not Starting In Hot Weather?
Aug 1, 2013
Passat 3.6 ... The 4Mo has been out in AZ for about 8 months now. After leaving it in a garage for two months when i flew back home, i came back to find the battery completely dead. It was periodically started but one day my cousin told me it didn't even unlock anymore.
Battery died and was replaced with a "hot weather" one. AAA guy laughed when he saw my plates and checked the battery to find it was a "cold weather" one that wouldn't stand a chance stagnant in the heat.
Coming out of class yesterday where it was HOT and sunny all day, my car didn't start. After giving it another try and some gas, it finally turned over and started. This happened before on my old battery once too, very rare, but it sketches me out that it happens at all.
Could this be a problem with the starter or just hot weather? I don't remember this happening in NJ, but an upcoming road trip makes me wanna know what I am working with.

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.

Due to the cold weather, seems the battery could not start the car. I removed the battery to trickle charge it overnight in the house, and hooked it back up in the morning. It seemed to have sufficient charge to power the starter motor, but the engine would not turn over. I could hear a whirring sound whenever the key was turned, and the sound stopped whenever the key was turned off.
I am suspecting that the starter motor somehow is not engaging with the engine flywheel?

Recently my 2005 VW golf has not been starting in hot weather. The radio, lights, and every other electronic will start when i turn the key. I will push the clutch in and try to start the car and the engine will not even try to turn over. I hear the starter kicking in so I know its not the starter. I had multiple mechanical tests done and no results came up. No warning lights are on. I brought it to a mechanic and he replaced the clutch relay... and that didn't work. If i leave the car windows open for about an hour after the interior of my car gets too hot the car will start. So I am thinking if it has to do with a relay in the cab of the car. What this will be or what I should try?

My Chevy Cobalt will not start in cold weather. I don't think bad battery is the case here because it's started in warmer temperatures. What could be wrong??

So I did a couple searches and found a couple MK3's with this issue however I did not find anything for the MK4.
The last couple days, we have been over 90 degrees in the afternoon. My black 03 20th 1.8t sits on the side of the road at work in the direct sun from 12:30 (lunch) until 5pm when I get off.
The last 2 days, when I have gone to start it, it cranks and cranks for 5-8 seconds before it starts to catch and finally stumbles to life. Once its running, everything feels fine. If I turn the car off and restart it, it starts fine.
In the mornings in the garage, evenings when its cooler or leaving for lunch before the day has gotten really hot, it starts fine. It only seems to be affected after sitting in the direct afternoon heat for a few hours.
I have read vapor lock, dying crank position sensor, ignition issues, starter etc. I am going to rule out the starter as the car cranks like normal. It simply does not fire.

My 1988 Volvo 240 DL often has trouble starting in the rain (I've usually managed to get it going, but it often takes several attempts). I have been told by a friend that he had the same problem with his '86 and replaced the distributor cap, solving the issue. My mechanic told me that he would need to replace the cap and wires. He said that replacing the cap alone won't solve the problem, and would just lead the cap to wear out faster. He told me this without looking at the car. Just want to know if he's right--do I need to replace the cap and wires? Is it possible that changing the cap alone will solve the problem? Could I change the cap and see if there's still a problem, or is it better to just do it all at once?

So I have a weird situation. My Sonata GS with the 2.4 engine has trouble starting ONLY during cold weather (-2 or colder) if it's been sitting for a few hours. If the weather is warm, then it starts fine most of the time. The car tries to 'fire' for about 45 seconds before it does; and 'fires' with no hesitation at that point. The car runs fine, no hesitation or rough idle. I've cleaned the intake system to make sure it's not clogged or dirty, replaced the air filter, cleaned the MAP and throttle body. My battery died a few weeks ago, so I've even replaced that. What this could be? Everything I've researched or looked into would throw a code, or have symptoms while driving...yet it runs fine once it's started, and no codes/lights are showing. Don't want to just start swapping parts hoping to find the problem...

My 2006 Ford Fusion SE V6 has trouble starting in cold weather. Once it starts, it's fine throughout the day, but once it sits a long time, like overnight, it has trouble starting in the morning. If it had a carburetor, I'd say the choke wasn't working. The dealership couldn't figure it out a few years back. I even tried a new battery and that didn't work. Is there a sensor that detects cold weather and increases fuel flow or chokes off air flow for richer starting mixture that could be failing?

Lately, I've noticed that my car starts fine in cold weather. But, once I put the car into drive or reverse, it stalls. Also, once I start the car let my foot on gas for few min, and then put into drive or reverse, it drives fine.

When the temperatures drop to the single digits and below, my car won't start. It won't even turn over! I turn the key and there's nothing. So, I sit in the car and then turn the key again. I wait. Then turn the key again. Within about 5-10 minutes, the car starts and its good to go! I've had a new battery installed. And even with the new battery, it does the same thing. At the shop, they check the battery and say it's fine.

How to diagnose what I think is a failing alternator?
Here are the symptoms:
- Hard starting in cold weather
- Battery not at full voltage when truck is parked (usually around 11.5-12 volts. I have been putting a charger on it some nights)
- Lights seem to dim when I've got accessories running, like heater fan, heated seats etc. Lights get brighter with engine RPM, like when pulling away from an intersection.
What's my next step to diagnose this? I did a search, and didn't see anything. My battery is probably still under warranty, so if that's the issue, it should be a free fix. How hard is it to install an alternator in a 2005 with 5.4L engine?

Vehicle: 1995 960 wagon
Background: Exhibits intermittent no-start behavior in both warm and cold weather, wet and dry weather, having sat overnight, or only sitting a few minutes. Turns over fine, but won't start. Sunday, it started fine several times, went to Home Depot, wouldn't start. Called a friend to pick me up. When he was almost there, I tried it again and it started back fine. Been in shop a few times, they played around with a few electrical connections, battery cables and grounds to injectors. Also replaced fuel pump. I have not verified if it is a fuel or spark problem, I just bought a FI fuel pressure gauge last night.
Once started, it does fine. It never stalls or cuts out. That is why I am leaning toward a CPS (that's what jeep people call it.) Sometimes, under the slow cranking speed (relative to idle) the signal is too weak to be useful. However, during idle and normal operation, the flywheel is moving fast enough that the signal is much stronger (being a magnetic pickup). Thus, the reason it only happens during starting, not during running.
Here's my current working theory: Bad crank position sensor (is that Volvo people call it?)
This is the only part I can think of that would cause this. A fuel pump problem would probably show up during running. I think the pump also receives a signal from the cam sensor, so if that sensor were the problem, it would happen during running too, not just starting. It the cam sensor an optical sensor? Shouldn't cause it to not start, although it might cause a difficult start.

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?

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.

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!

Our 2002 Passat 1.8 wagon has major electrical issues. Problems with the door locks, interior lights and believe it or not, the car will not start in the hot weather. The car also has to be started everyday or the battery gets drained for some odd reason...

I just got my wagon (2002 used) and noticed that the chrome detailing around the back windows of my wagon were getting really foggy in the super humid weather. What is the solution? Wait for winter? I assume the high humidity is just causing condensation in the plastic/chrome or whatever and when I press my fingers hard to it it goes away (consistent with moisture). Can this be fixed? She is so adorable without these clouds!
