I agree with Nick. If your car is typical of the limited mileage now run by most A7s, I believe the standard 6-volt dynamo system to be perfectly adequate - and a rebuilt dynamo will last a very long time. In today's traffic conditions, LED bulbs mean that the headlights can, for safety, be used as running lights (or as required in bad weather) with their low draw meaning that the battery remains fully charged.
