I've had a 2013 Audi A5 for about three years and the random warning lights and intermittent starting issues were driving me insane, especially after two other garages just kept replacing the battery and alternator without fixing anything. A guy at a local car meet recommended a place that advertises themselves as Audi A5 complete car repair specialists, and honestly I was skeptical at first because that phrase gets thrown around a lot. But they actually took the time to trace a corroded ground strap and a failing door control module that was causing a parasitic drain, and now the car starts perfectly every time and no more Christmas tree on the dash. Has anyone else here dealt with weird electrical problems on the B8.5 generation? It's such a relief to finally have it sorted without selling a kidney.
