I thought I would be immune from repair expenses by leasing ... Think again. The "service engine soon" light was illuminated on my 2008 335xi. No worry; I'll just drop it off at the dealer and check out a loaner 330 sedan for a day or two. The diagnosis: a fuel system vent hose had been chewed through by a mouse. Needless to say, that's not a covered defect. Bummer ... So now both my BMW's are out of the garage, and the cat has been sent inside to try to collect $250 from a mouse with expensive tastes in German rubber.
