If you're lucky, dmax will have his hose with him and help you isolate the source of your chirping...he'd probably check AC compressor first if I know him. He's not that funny...so you're better with his hose, if you know what I mean?
Upcoming NYC dates: Jan 8 and 27. See Facebook for other shows and PM me if you can make one...love to see you there!
Mangofy your E46!
