AC on an '03 Audi?

Do you mean freon?

owners manual? Button with a snowflake on it? Freon may be out, or may be a leak in the hose that the freon travels through to get to the system. Stop running it if you can’t figure it out, and take it to a dealership. Make sure whoever looks at the vehicle I’d ASE certified in AC and have them spray the tubes and check it with a black light to see if its leaking. If its not leaking, then they can go from there. Trial and error.

Many dealers, especially around this time of year, offer A/C system checks for a nominal price. Let us hope it is one of the minor things it can be and not the compressor.

so what was it? Did you find out?

needed more coolant…

@nocounry2 Congratulations! A nice cheap problem.

Definitly an easy fix.
