Hello Ray,
I’m not sure whether these light issues are covered by the 3 year warranty, but (pessimistically?) it wouldn’t surprise me that they declare they are not.
To me, the most urgent action needed at this point is to e-mail the Service Manager at your servicing dealer, and record the faults. I would also copy in Audi Customer Services.
Such notification should counter any claim that it will be out of warranty by the time that they can book it in for inspection.
Perhaps you could let us know how you get on.
Kind regards,
Gareth.
