Thanks for ur reply why Audi is charging a considerable sum for renewal is reprehensible after 3 years they just do not care but I have the solution when I change my car it will not be for another Audi
My 2016 Audi a5 has only just started making a noise like rattling tappets or camshaft ticking disappears after a short time only happens on cold start 24k miles a bit alarming i have now had 4 audi's first time this has happened
