2009 - 170 TDI Black Edition. Was driving home from work last night and the warning came on that the numberplate light bulb has blown. On closer inspection today, it looks like the plastic lens has fallen out and the whole bulb assembly is missing. Is this a common thing? I'm popping it down to Audi's later so they can either do it there or order the parts for a return visit. The car is a lease car and out of warranty so wonder if Audi will cover this under goodwill (especially if its a common issue) or the lease company (its on a fully maintained lease).
