Quick random question for you all....
I've had my 1.8T for a year now and I've noticed on a few occasions when I arrive home in the dark, lights on (dipped beam) when the rev's drop when coming to a stop the headlights change brightness very slightly.
I've tested battery, alternator, wiring and the bulbs but all check out fine.
Is this a known function / issue ?
Cheers moooocha Bunj.
