Ac went out had it quickly checked because the closest Audi dealership is 2 hrs away... Mechanic said its computer problems... Ac had been acting weird for the past few days smelling funny not working good any suggestions? Any DIY suggestions that I may be able to do before I drive all that way. I appreciate any responses.

 

any lights on in the car? Coolant lights anything?

 

No ... No lights or anything

 

What kind of smell? Typically musty/moldy smell or coolant/refrigerant smell?

If it is the musty/moldy smell that is typical and you need to flush out the a/c vent. It is possible that it could be so moldy as to restrict airflow and 'freeze' it up. There is a procedure in my Chilton manual to clean the core. Basically it is a high level aerosol cleaner to spray into the cabin air intake that will disolve and clean the mold. Then flush.

If it is the coolant/refrigerant smell than you likely have a system leak and it now stopped as it doesn't have enough pressure to run. In that case you should be getting lights and faults. The ECON light would stay on permenantly most likely.

 

yea i would say u are in need of a flush. Your thermostat flap might be stuck not allowing flow.

 

my ac went out not to long ago and it turned out to be empty just needed a refill of frion (however its spelt) i didnt have the econ light on which i was told should be on when i took it to the dealership. Im still looking for a fix for my heating though went out a month after i fixed the A/C i believe its a plugged core but 200$ just to flush it
