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.
View 13 RepliesWell 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.
View 9 RepliesI 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?
Great car, Love it! It's a big improvement from the 2006 Prius.
When applying the brakes and holding the pedal down, I notice that the indicator for slippery/traction yellow icon appears in my dash when completely stopped.
There is no map option on the steering wheel that allows you to switch back to the Nav/Map system on the HD display. Is there a voice command?
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?
I am away for a week and a half, the Touareg is at LAX in a indoor parking garage (WallyPark) the whole time. When I come back, the battery is dead. What is the probability of this actually happening? I know that it is common on 04's but I don't know how 05's are.
View 3 RepliesI have had the dead battery problem as well as the high / low shifter lights flash on and off. I also had a warning message called "workshop system fault" or something like that.
View 2 RepliesLast week i took my '04 V10 in for tires/brakes/rotors with a local service shop. The next day they called saying one of the service attendants must have left the keys in the car overnight, because the battery isn't working right.Here is what happens (all within about 15 seconds)
1. Put key in ignition, engine starts normally
2. Multiple error lights immediately start flashing (engine, glow plug,tire pressure, etc, etc...
3. The MFI screen goes black (like the Tony Soprano finale)
4. the center console flashes "safe ..........." for a split second then goes blank as well.
5. the a/c does not run at all during this
6. the engine RPMs will not increase despite pressing on the accelerator.
7. the engine suddenly stops.
8. everything is then dead on the car.
This all takes place over about 10-15 seconds. This entire process can be reproduced by taking the key out and starting over. They are shipping the car out to a dealer for further evaluation, their computer gave them some sort of "battery learning error", but they were unable to reset it. I haven't heard of a dead battery behaving like this. The Touareg never ceases to amaze
My touareg was towed to the dealership a couple of weeks ago for a dead battery again. 11 days later my dealership fixed it along with a list of other problems
My VW dealership's staff handled everything every well. The service manager was both professional and caring, however I did have to bring it back 2 more times due to items left in disaray by the techs.
Anyways, back to the fix....They said it was due to a bad "rear hatch micro switch" Now I've read a lot of about the dead battery issue on this forum & I have never seen anything about the micro switch. Could it be true...did VW really figured it out Or am I just dreaming.
I have had my TREG for 5 weeks now. It has 650 miles on it. I left it over the weekend and it was dead this morning. The key didn't even unlock the door remotely. This vehicle has no NAV and is 2006. I have read other posts, but they all seem to be for 2008. it is going to to the dealer this afternoon.
View 5 RepliesI had left my car for about 30 hours without driving, which I've done before all winter with no issues. Went to start it up yesterday morning to head out and when the key FOB failed to open the door, I knew I was in trouble.
I unlocked the door manually, and put the key in to start it up and the Treg was completely dead and the key wouldn't release from the ignition. After a call to VW roadside assistance, and a jump start, it started right up and I dropped it off at the dealer for them to look at.
The service report says "diag and found low state of charge. charged battery and found passes tests. performed TSB 27-05-01 and cleaned ground point for battery. rechecked OK"
This is a V6 Touareg (there is a similar TSB I understand for V8s).
Is my screen fried? Cold weather came in and the screen died and the fuel icon showed up... Even tho I recheck if the guy lid is open...

View 12 RepliesI just got my dream car, love it, but have two questions:
1. My battery icon is never totally full. Does that last bar ever show up? I doubt it's an issue, but figure if the charge is low now....
2. I've filled four times, and each time the computer shows mileage about 5% better than the actual purchase of gas calculates out. So I'm wondering if the calculation is a little high, of if my gas station is "a little off." I plan to use a few gas stations and compare the results.
There is what appears to be an icon on my touch display that resembles the battery icon on my smart phone. Currently is has one red bar lit up. I have not been able to find anywhere in the owners manual what this battery icon means and what to do when it is red.

View 4 RepliesOur 2011 SD 6.7. 190,000 km Came home after a week off and started the truck up via the command start, when I got in it the little red battery icon was lit up on the dash. Well this is my 3rd SD and in the past I always ended up needing an alternator when that light came on. So off to the dealer and was about to replace it, the service rep. stated the alt. was ok and there was something else wrong and it was turning the light on.
So you think here goes my next weeks pay looking for the Needle in a hay stack. Guys the Tech who is a great guy found a 18 guage red wire that runs from the pass. side battery under and infront of the motor not in any real wire harness and it goes to the alt. had some corrosion forming in under the insulation causing some resistance, and it was telling the system to turn the dash light on.
The tech replaced the bad wire and all is good now. Also you can test the out put of the Alt. and it will show around 15 volts with the truck running even with the red icon on, so you will know it's the bad wire and not an Alt.
