Doesn't want to start after driving for a time. just put a new battery

SOURCE: Battery wont keep charge

It seems as though the battery is feeding something that is turned on. Turn everything off in the car with the battery fully charged. Fold down the rear seat and see if the boot light is on. The problem can be found by trail and error. If you know a mate who can use a multimeter then he could do a check on the battery. If the battery is loosing its voltage, take out one fuse at a time to isolate which curcuit is drawing the power.

There is a small black box under dash by steering column that has a little red button on it. Push that button and it will reset the alarm. Whenever the power is removed from the system it will trigger that alarm and flash your lights. Easy quick fix. Box is about 4" x4" and just to the left of the column. Good luck and have a great day.

I had to take my car back to the dealership twice. First, they replaced the ignition switch. 3 days later, my car wouldn't start again. So I took it back and they called VW - VW said to replace the steering column module. I asked my dealer why they didn't replace the steering colum module first - they said that even if they had replaced that first, the old ignition switch would have shorted out the steering column module. Whatever.
$600 later my car has been fine for about 3 weeks now. If it happens again I will keep you posted.
Good luck!
