Hi Q-List, I will shortly own an Audi Coupe Quattro with air, but the condenser is broken. Audis price is too high, so I would like an aftermarket unit. Any ideas? The next issue is the use of R134a. I need a new dryer and Audi does not make one. This A/C system is the same one used on Ur-Quattros. Has anyone actually converted their car? If so, please email me details... Kind Regards Rob Germany
