My son gave me a scare a couple of days ago... we were on a trip, and he was home, using the X5 (better traction than his e36 in the slushy, snowy, crappy weather we missed!) He drove it home & parked it outside, and the next morning the clutch pedal was hanging mid-stroke, and the engine wouldn't start. When we returned last night though, the clutch was fine, and the battery was too low to turn over the engine; nothing a battery charger couldn't fix. I'm guessing that the clutch was maybe caused by some icy buildup around the slave cylinder that thawed out in the interim. Just thankful that my wife has a working vehicle!
