I’m new today! Have a question about my 2013 Q5 hybrid 72k miles. Just after (a day!) my 65k servicing at Audi Grapevine TX a light came on with a manifold fault dealer estimate repair of $1600. I thought they must have jiggled something during the servicing because too coincidental that it’s the next day! Light stayed on for a couple of weeks then went off with NO driving issues. Now I’m selling privately and mechanic check shows light again! Thoughts?
