I have repaced battery under drivers seat, only took 55 mins but want to know exactly where the second battery in the cargo area is and unable to find it by simple visual check, must have to undo something to get to it. Does any one have any idea.

V8's only had one battery. The V10 had two.

As above then - look under the spare wheel. Some people did fit a second battery if they were into towing vans.

Why a second battery in V8

I read all the replies to the person looking for the second battery in the V8. I deduced from all I read that there is only one from the manual. My question is: Why would there be a need for a second battery. One reply seems to indicate they installed one.

Thank you,
PS: I am having battery problems, does not seem to hold a charge but replacing with new tomorrow?

The V10 was the only Touareg fitted with two batteries as standard because it had so many electrically operated extras: one battery dealt with starting it, the other with the goodies on board.

Here's a how-to on battery replacement if you need it:

Many diesels have two batteries due to the tremendous load starting a diesel takes from a battery; my F250 diesel has two Type 31 batteries that need changing every three or four years. The V8 has many of the same electronics as the V10 so its not about the electronics...

After replacing my battery beginning to think its something else thats causing the problem. Twice now I have caught the car with an alarm sounding (no lights) have not been able to turn it off using the key fob or ignition, actaully the power dies while key in ignition and unable to get it out untile car restarted with a jump start.

If it is proper to just say Thank You here then Thank you very much, that is comforting to know.

The V8 is petrol, the V10 is diesel - a VERY different starting proposition especially in cold weather!
