There are similar issues with the door mirror mounted puddle lights on VW’s mk8 Golf where the projected image has become distorted - often within a short space of time. With VW in the UK, where this has happened within the warranty period, the puddle lights have been replaced free of charge.
I never had any issues with the puddle lights on my mk6 Golf which used ‘normal‘ bulbs; they just always worked as they should. Why does VAG feel it is necessary for a car’s puddle lights to project a model-specific or brand-related image that are prone to fail rather than just provide a simple, reliable source of illumination; the saying ‘if it ain‘t broke, don’t fix it‘ springs to mind.
IMHO a definite case of form over function with questionable durability - and a bit gimmicky.
