I had an unfortunate mishap on the highway last week where a metal rod was picked up by a car in front of me and it punctured my condenser and all the freon leaked out. It also broke my front grill but other than that the car is OK. A friend of my own a body/repair shop so I was able to repair the car but he is not sure what kind of oil to use to recharge the A/C system. Can any of you help me out and let me know the right oil. It is a Denso compressor. I did some research and I know there is two type of oil for Audi's but I don't know which one is the correct one.
