I 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 RepliesWhen I exit and lock, the window sill red lights flash for a while and then stop. I seem to recall they previously flashed continuously until car was unlocked. Now, the only flashing red light that continues is the tiny pair on the nav radio.
View 10 RepliesSo today on 2008 v8 Treg my hazard lights just start to randomly flash on my drive into work.
I would get one or two flashes, then another one or two every 1-3 mins.
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.
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?
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.
View 13 RepliesMy new battery was draining down overnight. Thinking it wasn't charging back up properly I replaced what I'm sure was the original alternator. Now sometimes the engine lights (battery,brake & oil) flash on and off when I accelerate. So far the battery hasn't gone dead again.I also had an oil change. They put 5.7qts in the 6 cylinder engine.
View 7 RepliesI 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 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).
On Monday morning, I turned the key to my V8 and nothing happened. No lights, no chime, nothing except the radio still worked. I called VW roadside assistance and the AAA guy who came couldn't jump start it. So the truck had to be (in park with the steering wheel locked and the key locked in the ignition) dragged onto a flatbed ...
Now one week later, they still can't figure it out...except to tell me that it's not the battery... I should have bought the Lexus.
Prius, 08, smart key. Dead on Sunday am, nothing works. Put trickle on the underhood positive and neg to body bolt. Got enough juice to open rear hatch (and dome light comes on ).
View 18 RepliesSecond dead battery in 2 years. ??? Car never sits for longer than 12 hours and no internal lights on. I have a III with Sunroof.
View 14 RepliesI went to open the hatch this afternoon to see if my new painting would fit so I could take it to the frame shop, and the hatch would not open. Nor would the door-unlock button work. The fob wouldn't open it either. Then I realized no dash lights were on, and the car would not start. I thought there was supposed to be a way to open the hatch from the inside, but I crawled into the back and could not find it.
So the 12-v battery was dead.
I stored my car with a friend for a few months and of course he let it sit too long. He had to do a running start and now the dash lights are a penalty. I'm still out of town, but I am getting on a airplane right now to come home and be with my R again. He said the car was cutting of at stop lights, I'm sure he drove it cold.
View 7 RepliesI have a Canadian spec TDI highline trim with automatic headlights. I generally do not lock it when I park in my garage at home. Last night I parked it and came out this morning to see that the running lights, but not the headlights, were on. The battery was basically dead and I had to boost it to get going.

View 4 RepliesI have a 95 Mazda protege. The battery went dead from leaving the lights on. We jumped it and everything was ok. Drove around, shut it off and it started again, no problem. The next day the car wouldn't start. Had dash lights, and it clicked but this time there is a high pitched noise. It is not an engine noise. I jumped it, it started right up. Tested the alternator, its putting out 14 volts. I could not find the source of the noise. I checked that all doors were closed and that sort of thing. I shut car off to see what would happen, the tone of the noise changed but car hadn't built up enough charge to re start.
