2006 A4, A/C Problem
 

Guys the dealer told me that the A/C condenser has hole from stone and the system is empty, I don’t know how is that happened but is there any fix for it or the condenser need to be replaced?
Any recommendation for who can fix the A/C?
Any rough idea about the cost?

There is no fix unless an exotic qualified aluminum welder is found. Then the receiver dryer will require replacement. It's been open to the atmosphere too long.
1. New condenser
2. Receiver receiver dryer
3. New "O" rings (at all times)
4. PAG oil system top up
5. R134 refrigerant
6. Evacuate and recharge

There are cooling and AC system aftermarket suppliers that manufacture these components, use Google, there's suppliers everywhere. Be aware, non OEM parts have their own problems with reliability and fit.

Only a qualified A/C technicians can service and repair those systems
