I've got a 2002 Passat 4cyl whose battery has been replaced twice in a month and died again today. I drove it for 30 minutes yesterday and found it dead about 24 hours later. Putting an ammeter in series with the ground cable, I only see a 10-20 milliamp draw with the car closed and locked. With the car running, I see 14 volts across the battery terminals, so I'm assuming the alternator is working.
View 5 RepliesI just bought a certified 2010 Prius and have had it for 3 months now. Twice within one month, there was absolutely no power to start the car because the aux battery went dead overnight. I'm pretty sure I didn't leave any lights on and don't think I did anything differently when exiting the car for those 2 times. I took it into the dealership, and they couldn't find anything wrong. They said the battery was good. What is draining the battery overnight?
View 5 RepliesWe spend summers away and our 06 Prius stays in the garage. I connect a battery minder and it keeps the 12v battery charged with no problem. I also turn off the switch under the steering column that works with the remote.
When I started the car after two months and driving for a few blocks, I noticed the MFD showed the battery at a low of two purple lines. After a while, it charges up normally. The car has 47000 miles and the 12 v battery has never been changed. Would that have something to do with it or am I being concerned over nothing?
today I replaced the battery on our 2002 Camry SE 2.4l because it was incredibly slow to crank today...but it did crank. So i get a Duralast Gold to replace a Toyota TrueStart battery, and it started up fine. However, it was idling at 200-400 RPMs, so its already not right. So I drive it a quick mile or so, and when letting off the gas the RPMs drop to 200-400 while going down the street! Coming to a stop, it really wanted to stall out. Couple stops later, it did stall out, and the Check Engine light, Battery light, and Oil light all came on. Trying to restart it it cranked, started, but then immediately died. You know when you start it the RPM needle goes high and then comes down a bit? It does that, but the needle won't stop and it just goes to 0, and throws the Check Engine, battery, and oil light. I finally got it cranked, and all 3 previously mentioned lights are off when its running. It has done it one other time about 3 months ago when I disconnected the negative battery terminal for some work, and it did the same exact thing. It ended up just fixing itself, but obviously not since its rough starting and the problem came back the next time I disconnected the battery.
View 14 RepliesI bought my 2002 prius with 120000 miles. Last night it died with the main battery light and triangle of death on. I haven't taken it to a dealer to have the codes checked out you, but will do it soon. My daughter was driving it when it happened and said the car started shuttering and died. She was able to drive it a few feet at a time before it would die again. Does this sound like a HV battery problem? I will be digging into it tonight.
View 19 RepliesI have a 2002 Toyota sienna XLE, 95k miles. A few weeks ago I replaced the battery with a DieHard. Immediately after this, the right sliding door stopped working. A few days later the left side stopped working. Neither sliding door works in the manual mode, child proof feature is disabled. Fuses are good. Both doors click when any associated switch is activated but don't open. It was suggested by an owner of an older Sienna that the auto door computer needed resetting. Worth a try. His procedure involved disconnecting the negative side of the battery, waiting 3-5 minutes, reconnecting battery, use the key fob remote to open a door and then close it using the fob. Wait 10 seconds open and close same as before, doing this a total of 3 times. It didn't work, door clicks won't open. Tried again same results. This makes sense and my thinking goes that perhaps the sequence is different for a newer model.

View 19 RepliesI have a 2000 VW Passat V6. Last night when I got home I noticed that the fan wouldn't stop and it was making a different noise than usually (ocasionally when I get home the fan keeps running for several minutes which seems to be normal, but yesterday the noise that was coming from the fan was different). Today the battery was completely dead.
I've been reading different forums, and it looks like it can be either a problem with one of the fans, or fan relay. How can I diagnose the problem?
My radiator fan didn't turn off tonight. Used to Audi's I didn't think much of it as they often run after car is off. Battery died later tonight. The fan will not turn off.
I tried pulling the fuses listed for the fan and it didn't turn off after I got home and would not drive the car anymore. Car sat for 3 hours when the battery died, so it was not a heat issue.I had to disconnect the battery to stop the fan and enable me to start the car again. How do I stop the fan with a fuse/relay so I can use the car until I get to the dealer? 2008 6MT
2012 3.6 SE... Might have left my lights on... Battery Dies... How do I get into the trunk where the battery is or to the connectors under the hood? I'm completely locked out of the car...

My call didn't start two days ago, turned out to b dead battery. Got it replaced at local euro shop but now AC is blowing warm air. Called the shop they say, they didn't touch any wiring related to AC.
*could there be anything they forgot to hook back up that's causing this?
* any fuses I can check?
* do our cars need AC recharge?
I replaced my dead battery today. Once the new battery was in everything worked just fine except for the radio. The radio is not in safe mode it is completely dead. The radio worked after my last jump. I had turned it off before replacing the battery. Now it will not turn on and the security light does not blink.
I have checked the fuse and it looks good. I have removed the fuse for a while and put it back in with no luck. Is there a trick to getting it to come back on?
So my car was having trouble starting about a week ago and it would barely start and finally friday I was trying to go to work in the morning and it didn't start i had to jump start it and it worked!
Well today I bought a new battery and installed it and the windows worked and radio i put in the code and it works but now my problem is the Alarm wont work!
Is there a way to reset the alarm ? I lock the doors with the key and don't hear the beep sound to my alarm anymore. And before i replaced the battery the sound was there but it was really low it wasn't how it used to be how could i fix this problem ?
I have a 2003 passat wagon v6 4 motion.
Last Thursday the battery was dead. I could jump the car and it was fine. Drove for 20 minutes to work and 10 hours later it was more dead than in the morning. I bought a new $150 battery, the heavy duty one, that Thursday. Friday everything was fine, 60 + miles. then Sunday for another 30 miles, no issues. This morning it almost didn't start, then later going home I needed to jump it again.
There is nothing plugged into any of the 12v power adapters. No Lights left on. Seems like it's not charging? So I was thinking alternator. Though reading on here seems Like i'd get some check engine lights/codes about the alternator??
What can I do to check if the alternator is charging? I have a meter and am good with electronics, but do not know that much about cars... Looks like the alternator is burried under the front left og the engine as you are looking at it standing in front??
My 2006 2.0T Passat is starting to give me the steering column errors. I've seen a couple people saying that the problem was rectified by a new battery. Seeing the car is out of warranty and this would be the 6th winter for the battery, I think it's probably good idea to try a new battery to see if it does the trick before going to the dealer. I've never changed a battery before, so what does it all involve? I have a 12V battery from my back up sump pump that I can use to keep the power up when I change the battery. I imagine that I'll just connect the back up battery to the leads, then disconnect the old battery, pull it out, put in the new battery, connect the leads to the new battery, and disconnect the back up battery. Does this sound reasonable? Is there a bolt(s) securing the battery in place that needs to be loosened before I can pull the old battery out of the bay?
View 4 RepliesThose nice blue lights that light up when you have your lights on just died on me. I have an 02' passat wagon v6.
View 4 RepliesI just replaced a burnt out tail/brake lightbulb and found that I had sockets for 5 lights yet only 3 were filled....two were empty. How could this have happened and shouldnt they all be filled? I replaced the blown one but I feel like I should get 2 more per side to make it a full housing. I also am not certain what kind I need . The turn signal bulbs are fine....it's just the tail/brake light bulbs. Why were they not filled? 2002 V6 Passat.
View 7 RepliesMy battery went dead so I replaced with new. This did not fix the problem so I replaced the alternator. It's working now but the battery light stays on. I think I still have a problem.
View 3 RepliesI have a broken gas gauge so i pretty much run it until its empty. Has been fine but just died about a week ago. Nothing else was wrong with it. Worked and ran great after for about a week then i went to start and it did the same thing. I have listened for the fuel pump and it sounds like its working. I have not checked the fuses...I am curious what else it could be if after one week with a fuel filter it would do it again
View 17 RepliesI'd like to know how to replace the battery in the key fob for my 2002 Passat Wagon. I looked in the manual but I could not find it and it says that the dealer should do it. I am aware that sometimes the fob may need to be re-programmed but my wife's key works perfectly so I will assume that the battery has gone out. The key works just fine when used manually.Also, what kind of battery does it take??
View 2 RepliesI have a 02 1.8t passat that if I don't start it for two days the battery will be totally dead. I have taken it to two places and they cant find what the draw is. The only thing that i could think of is my horn that sometimes when I am in the car it goes of randomly and my right side mirror that sometimes runs on. And my other problem is that when I drive it and I get to 3500rpm the throttle body shots of and I loose all my boost. I got a new turbo installed trying to fix the problem but still keeps happening. The only thing I could think of is that i have a stage 1 revo flash and when I took the old turbo out it may have erased the memory of the flash.
