so my battery light came on yesterday, so i tested the battery at work, perfect, also checked the charging system, great. then on my way home from work, my cluster and radio/climate/window switches all out, but they react to the brake switch, on when pressed, off when released(sometimes) the blower motor also loses speed at idle compared to normal speed when rpms are up..
View 3 RepliesMy wife was driving this morning and the car stalled when she was accelerating from a stop light. Battery light came on and she could not restart the car no power. When I got there she was able to start the car again. I drove 10 feet when the car stalled again. Noticed that the EPC came on smelled rotten eggs or sulfur from the exhaust.
Used jump cables and car started, battery light gone but EPC light came on and stays on, no blinking. I drove back home about 13 miles and no problem. Took battery to test and did not hold charge, I will replace battery. Car was at the dealer for two weeks to get the CAM, cam follower and high p fuel pump replace. Is just a battery issue or another issue for the EPC light?
Checked the belt & alternator pulley but nothing wrong there. Battery looks good too. What can it be?
View 10 RepliesSo, I have have an intermittent flickering of the battery light. The weird part is that it ONLY happens between 80 and 85 mph. Any faster or slower and it doesn't happen. It's not a steady flickering, but a random intermittent flicker. What the issue may be? The car has a new (within 2000 miles) battery and alternator. 1.8t with manual transmission.
View 3 RepliesThe car is an '06 Passat 2.0T 83k. A few weeks ago my wife came home complaining that the battery light was on, when I lifted the hood I saw that the belt was shredded and later realized the compressor seized. I replaced the parts recommended; Compressor, condenser,etc., brought it to service station that does our fleet cars and had the system vacuumed and recharged. Now the compressor will not turn on, when I push the button on the dash it lights up but no a/c, the fans dont even come on comes on. The blower and all the related switches works but no power to the compressor. All the fuses are fine, and when the guy at the service station put power directly to compressor it comes on and works fine, he also said the pressure sensor/switch checks out fine. I even changed the controller on the dash, but nothing.
View 11 Replies195K, B5, 1999, AEB. The battery light on the dash is flickering...mostly off, but the light (battery symbol) lights up ever-so lightly...then off, then on...on for about half of a 45 minute drive last night. Voltage regulator? Alternator? The battery seems fine, as it turns over after a cold night...
View 6 RepliesLike the title says, I was driving into work today and it came on three times. It went off for a little each time and then came back on.
View 13 Replies2006 2.0T with 86k miles. Anywho, a few days ago I attempted to start the car up & it felt as if the engine started up then immediately cut off & the red battery light would show up. I then tried to restart it up and it fired up successfully & the battery light immediately went away. well today, i drive it to my grandmothers house and have dinner, come back & fire it up and the same thing happens. only this time i had to try about three times to start it up successfully. I am aware of the whole steering column lock issue but it didnt say this at all on the mfd display screen. is it safe to drive around?

I have a B5 Passat that came in with the alternator workshop light on. Upon a few tests i determined the alternator was bad. I removed the alternator and installed a remand one that was correct for the vehicle. amps and all. After getting it all back together i started it and the car ran fine. I drove it around and shut the car off. Customer took the vehicle and after 15 minutes the car was back for the alternator workshop message being on and battery light again.
I restarted the car and it was off. I restarted it again and it came back on. Replaced the Alternator again with another and took it for a more extensive drive. The lights stayed off this time. I parked the vehicle and shut it down. Waited a few moments and restarted it just to be safe, the lights had came back on again..... After testing it more I've come to find that when the lights are off the alternator is charging the vehicle as it should and when there on the vehicle is not charging. I don't know what it could be at this point but I am absolutely sure its not the alternator.... I honestly don't think this many are bad in a row.
I was putting in a subwoofer earlier today, and after I put everything back together, I turned the ignition to ON just to test out the system, and all the electronics worked fine.
However, when I went to crank the engine, nothing would happen, not even a click or crank. I tried jump starting the car, and it would crank and crank and crank, but wouldn't go on. All the electronics still worked fine, but the EPC light, CEL, and battery light would be solid. While cranking, the battery light would occasionally flicker.
I got a 99 1.8t. Here's the deal, misfiring at idle, flashes battery light. alt and battery was checked and there great. it has a maf code, so I unplug the maf and still get the same misfiring. maf was fine be4 i tried cleaning it, now it throws the code. it had misfiring be4 i clean it also. next problem is it stutters and misses if i go wot in 4 or 5 gear and the batt light flashes it doesn't throw a misfire code. Also if I am idling and i floor it, it stutters and misses at lower rpm rage and then is fine at higher rpm range. i replaced plugs and gapped em right, i did a power balance test and the coils all are firing so is the injectors. I don't got vag but i do got a good obd2 scanner i was looking at the data wen car was off and i seen that if i floor it the tps only reads 77.7% . Also my timing says its 12 degrees and idle fuel pressure is fine i checked with a gauge. Pretty much misfiring with no codes thrown and flashing battery light.
View 17 Repliesthe car's battery light still has not shut off and now the defrost button stays on for about one second. The engine bay sometimes smells of something burning, too.
No CEL, so what's going on here?
2.0t 2006 auto Passat: Push key in, car turns over, rpms settle out, then drop out and battery light comes on. When this happens it will do it several times then fire up normal. I tryed starting it with the gas mashed and it fired up revs went up then dropped out and died. This has only started happening today. Also about a year ago had a problem with battery draining after car sits over night or for long periods of time. After VW replaced a few relays and assorted parts they changed out a window motor and that seems to have fixed that issue. No problems till now.
View 24 RepliesDisconnected my battery for about 15 minutes to wire up HIDs. Couldn't put them in due to the nut not coming off the battery bolt. tightened battery and started car. dash has amber steering light on and traction light. when i put it in reverse (AT) it banged into gear, then put in "manual mode" trans jumped and banged into 3rd gear. also noticed 1 touch windows not working. What might have gone wrong from a simple battery disconnect. no additional wires were hooked up to the car or did i forget to reset something.
View 4 RepliesRunning my fog light setup and stereo make me what to get something like this with all of the wires in the battery.

My 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 Replies2002 Ford Focus SE with 130k miles on it. For the past 4 months the battery light flashes randomly while driving. The flashing and frequency of flashing doesn't seem related to anything I can tell including temperature, length of time the car is running, speed or any variable. Seems like it should be an alternator, but that was replaced less than an year ago and it also has a new battery. The alternator always checks out fine at the mechanic and it will never flash for the mechanic. It went 1 month with no flashing and suddenly it will now flash maybe 20 times in a 5 mile drive. Yesterday it just died at a stoplight with no warning, but then after shutting everything off it started just fine and the battery light didn't turn on for the 2 miles to home.
View 5 RepliesUnhooked battery on 2011 truck. I unhooked mine today then installed my magnaflow exhaust. then i hooked the battery back up. And now my battery light comes on when i turn the key ahead. my sync doesn't work, i push the button and it won't say listening. and when i turn the key off the stereo won't stay on, it says it's shutting the system down to save the battery. i am going to take it in on monday to see if they can fix it. i just hope it isn't my fault. Any certain way of disconnecting it.

So the other day I was driving home and i noticed my battery light was coming on each time i stopped at a red light. Soon after it remained on regardless and the voltage gauge started to drop till it hovered right at the "N" in normal but thinking if my alternator had gone i was best to keep driving rather than having to stop and restart the car again. I shut the radio off and made it home. The next day i grabbed my haynes manual and started going through all the tests of the charging system and everything checked out.
The battery had a full 12.8v at rest and when idling showed 14.3, whats going on? The car didn't have a problem starting the next day and the battery, even now another day later, has a solid 12.8 on it so I don't suspect a drain anywhere. The only thing that i notice is when i tested the resistance on the voltage regulator the manual calls for at least 2.4ohms and mine read 4.0ohms, is that normal? Could it just be that my actual gauge is bad and i am getting a false reading? My only other thought here is maybe the drive belt is a little loose and its slipping when the alternator is under load, but I don't hear a squeal and when i measure the deflection between the alternator and powers steering pump i get a little less than a 1/2".
The past few weeks the dashboard warning light for my alternator/battery will occasionally light up while driving down the road. Whenever it does, my plug in voltage meter shows a healthy 14.x reading. It usually goes out after a few seconds, but will stay lit up for as much as thirty seconds. So other than voltage being too high or too low, what else will cause the dash trouble light to illuminate?
