Hey there, My 87 535iS has a clutch problem in cold weather. It's rather stubborn below 32F getting it in gearin the morning, works after some warm up. Could this be moisture in the hydraulic fluid? Doesn't seem to have any leaks in the master or slave? Thanks Bob Krejci 73-2002, 87-535iS, 72-R75/5 and a 68 280SL ------------------------------
