Air Conditioning Intermittent

[SlowRolla]

I have a 2019 RS5 and the A/C is being odd. Sometimes the driver side takes awhile to get cold, sometimes its ice cold, but the passenger and rear vents blow warm air, even after the driver side starts to cool down. Any ideas what this could be?

Just in case anyone searches. Turned out to be my evaporator which Audi extended the warranty for this part to 100k miles.
