AC Condensor Change
I will need to change my AC compressor soon. It makes intermittent tappett type sounds but still puts out way cool air. I have been told that waiting till it completely craps out I am risking a much more serious job of having to flush the system. Is there any truth to this? Being really strapped for cash I am thinking about either used or aftermarket. Has anyone changed this on a 3 series and if so was OEM or aftermarket used. Also I found a new compressor on e-bay for a good price but they said in order to validate a 1yr warranty a new drier had to be replaced at the same time. Is this necessary?
