I had my car parked in the garage for the last 4 months during the Chicago winter. I started it once or twice during that time. Last weekend I started it up for the season and noticed no pressure in the clutch pedal. The reservoir was empty, about a shot glass low. I found nothing on the ground under the car and no visible leaking. I topped it off and it seems ok for now. Should I be concerned? It can’t possibly evaporate. Anyone else ever had this experience? It’s a 91 TT with 45K original miles. Everything is like new. I have owned it for 15 years and this has me stumped. Thanks.
