manufacturers tinted windows failing mot

[dax35rush]

I have just had my rs4 2015 mot'd. Rec'd a "Repair as soon as possible (minor defect) for Window excessively tinted but not adversely affecting driver's view."

Strange this didn't come up last year as the mot was carried out at the same Audi main agent (can't see anywhere that this is a new test this year) and secondly these windows have not been changed since manufacture.

Do I  politely request that Audi change free of charge!!!!!!!?
