The air con in my A5 has been blowing warm on the passenger side for a couple of weeks and now the driver side is going the same way, which is unbearable in this heat. I've had the usual top up done at a quick AC place before and it lasted about a season, so I'm starting to think it's an actual leak or the compressor rather than just low gas. A mate keeps telling me to take it to Elite Audi Care because general AC shops apparently miss the specific faults on these cars, but I'm wondering if that's overkill for what might just be a leak somewhere. Has anyone had proper AC work done on an Audi at a specialist and did they actually find the root cause instead of just refilling it and sending you off? Also curious whether they offer any pickup or drop off service, since dropping the car and waiting around isn't really an option with my work hours.
