I have a 2002 cambiocorsa. The other day we drove it around town for a little while. When the engine was cut off we heard a whining noise coming from the gearbox. We have never heard this before. This noise lasted about 10 minutes. Now the car won't start at all, and the check engine light is on. Luckily the car was in our garage at the time. Any ideas as to what may have caused this?
