Touareg :: Conserving Battery Power?
Aug 29, 2005
Is there a way to turn off having the lights come on inside the car when you open a door? I have been camping several times this summer and have periods of time that I don't start my Treg for a day or more, but I am getting into the vehicle often to get stuff. I can tell when my battery starts to get lower because the lights turn off quickly just after I open a door, then when I start the car, I get the "workshop fault" error message that I used to get often when I had battery issues last year before VW replaced my wiring harness. The good news is it appears the car is managing the power by turning off the lights when the battery power is low, but I'd rather just turn off the lights entirely with some feature until I decide to drive it home, then turn them back on. I have not scoured the manual looking for this....

How I'd disconnect the battery power? I don't have the owner's manual handy. I'm attempting to reset all systems to clear a 'steering defect workshop' warning. I've removed the cover and think I see the battery (there's a black bar over it that I can't remove by hand).

Well my two weeks of Touareg bliss just ended with a dead battery. I guess two weeks out of car is all you can expect. I know I'm not the first... but seems pretty unbelievable in that I have never had such a problem with any other car in 35 years.

On my display, I get a "Key Battery is Empty" alarm with a little key symbol that stays there as long as I am driving. I have replaced the battery...still the alarm. I have tried the other FOB...still the alarm. The thing is, the FOB works (I have the keyless start) so it seems to be a software issue but how do I reset it without venturing down to the dealer?

I got my V8 back from a dead battery for the 2nd time. As usual, they have not found the problem. They said that there isn't any battery drain and the battery holds a charge. This time I took it back to my dealer I purchased from, not that it means anything.
I know there have been a lot of talk about different things that are causing the problem/ fixing the problem, but I have noticed that it may not be some of the ECU's, Navi/radio, etc. but could it be that when the vehicle is actually running the Alternator may not be charging the system significantly while driving when things are turned on, as in multiple things like AC/Heater, Fogs, heated seats, etc at the same time? Reason is that I have noticed with my V8, if you turn off all of these things the voltage gauge reads very close to 14 Volts and when you turn them on, it drops/cycles to about 13.75-13.5 volts. The dealer loaned me a V6 Touareg and with all these things on, the Voltage Gauge read 14 Volts solid most of the time or pretty close to. Meaning that the Alternator may be keeping up with all the things turned on (Current Draw).
With my V8, if you have these things on and you are running around town starting/ stopping without driving it for a period of time the Alternator may not be sufficiently charging the battery and then when you park it like overnight with the normal drain on the system in off state you may not be able to start it. Could there be something there or am I way off? Since they are always looking at the battery and if there is any drain on the system when it's off, is the alternator keeping up with the Touareg's requirements when it is running?

Yes, I STFA but didn't come up with a solution. This is displayed on driver info display, so i replaced the battery in the keyfob. The the keyless entry works a few times then all of a sudden keyless entry doesn't work and the display "key battery empty" comes on again. When i take the battery out and put it in again, same thing happens, works then doesn't work. The battery is good but this keeps happening over and over again.

Drove from KC to Wichita (189 miles) on Friday. Drove around in the city (probably less than 22 miles) that evening. Touareg has been in the driveway of my father-in-law's house since. Got in the car this monring (Monday) to go pick up my 2 nieces and the thing was dead. It didn't want to give my key back but I insisted so it did.
I have it on a charger right now and it is drawing 12 AMPS. I just hope the thing starts later today when i have to get back on the road to go back to KC.
Big bummer. Nothing unusual that should have caused the problem, but I do have yet another theory to add to the pile. This theory is a running one from my previous Jeep Grand Cherokee Ltd. It developed an electronic eye issue. When parked the eye sensor would malfunction and tell the headlights to come on. So, the battery would drain in my garage overnight. They replaced the sensor and the problem went away (which I thought was strange since the Jeep was off in the garage disabling the sensor from being able to tell the lights to turn on).
When I went out to the Touareg this morning I noticed that the parking lights were on (but very dim). When I switched the light switch to the "O" position they went off.
Do you think there is possibly a light sensor issue here as well? Who frinkin' knows?

I went away for a week and upon returning, I couldn't get my V6 to start. I couldn't get anything to work....auto lock, headlights......and then I discovered the battery has been discharged totally. I am really shocked as how could this have happened. I have checked everything but nothing seems abnormal as I remember checking every detail before locking up the car and leaving for my trip. This is the longest time which I did not use my car. Before that the longest was less than a day. Btw, the car is only 2 months old.

Last Friday, as I was on the way to a very important appointment (closing on my house that on the market for 7 MONTHS!), my Treg decides to stop running at the stoplight. I turned the vehicle off and on and nothing. The aircon is blowing hot air and the car would not start. After 4 attempts the car starts up. The battery light comes on.
In front of my house the Treg stalls again and this time the power steering goes out. I start it up again and make it home. I call VW Roadside and they were very useful and got a flatbed out to my place within 1 hour.
They tow it to Advantage VW and they run all sorts of diagnostics on the vehicle and test drive the vehicle 3 times. Nothing shows up. The service manager (Scott - awesome service) states that there is nothing wrong with the Treg and tells me to pick it up.
I show up and I start up the car and blast the AC (it's Texas and it's HOT). I wait for the AC to kick in and nothing....I return the car to service and I get a phone call 2 days later stating that they talked to VW Tech and now they are in the process of replacing the compressor, evap, expansion valve - pretty much the entire AC system.

Bought my 06 Touareg V6 two weeks ago. Well the battery died and couldn't start 10 minutes after I got her home. So the battery was replaced with a new one and it has been fine since.
Well except for the fact that I have a Gray interior and the dealer put on the lower trim panels in front of the driver's seat from a anthracite colored interior!!
Around the trim that would be taken out to replace the battery. I would like to make sure all the parts are there when I get it fixed. [URL]......

I was getting in my Touareg this morning after going to the doctor. As I turned onto the freeway onramp I noticed I had no turn signals at all and my battery voltage was pegged at zero and not fluctuating at all.
Had the battery replaced about 2,000 miles ago when I got the standard System Fault message, but it has started fine since. Even started fine this morning, etc.
Drove to the dealer while I was on the cell with my service manager who knows me by name.. I get there and shut the car off. Turn the alarm on and off and re-started it. Same thing....no turn signals and as I started it the battery voltage went up to 10 and back down to zero.
We're planning to leave it for service and it clears itself. Turn it on and off about 10 times with no error again.....very weird. Dealer needed to order some other warranty parts so they are going to check for any errors when I drop it off next week.
My voltage is consistently in the 12.5 to 13.5 range. Never at 14 volts. My tech at this dealer checked my vehicle the last time when they replaced the battery and said nothing needed to be replaced. Checked all the TSB's, etc. He and his wife have a T'reg so he seems to know his stuff.
I've heard the talk about the 14 volt reading, but he said that is not true, though it does have to have a 12.5 volt or above reading at all times per what he said. Service manager said they saw something similar last week and that owner was also getting some heavy radio static. I noticed some faint radio static, but was also listening to an AM station at the time. I do have NAV.

Every second or third time I turn over the engine, I get a warning telling me my key battery i dead. It's a 2006, so I can see how it might be. But the thing is, it still works from far away and the automatic unlock when I touch the handles never fails either.
Is it common to get a warning when there's still juice left in the battery or is this an error?

The yellow key icon came on in the MFI, which means the key battery is dead. The other key works fine.I'd like to replace the battery myself and reprogram the key (if necessary) instead of leaving it at the dealer for a day. How to open the key and reprogram? I looked in archives and the one set of instructions doesn't work. Nothing in FAQs.

I took the battery out of my key. When I replaced it, my remote does not work anymore. Does it need to be reprogrammed when you remove the battery? If so, what is the process?

Went out to touareg this am to go play golf...car would not start! 2nd time this happened, in 3 weeks! They gave me some BS about a signal coming from local station that puts radio in an on position waiting for a signal.
Well, I call this am to tow, the service MANGLER states that there software fix! Well, I will let them know I want a NEW battery...and the problem fixed. Also, tires a wearing a little on front after 20,000 rotation. I will see what they will do.

If I leave the radar detector on for two or three days and don't drive the car, the battery is so low it will not start the car. It is a 2005 Touareg with 25,000 miles. Can the battery be tested with the terminals under the hood, or does it have to be accessed under the seat?
