my car is fluctuating when cold, when hot runs really good, but i'm having a little problem even keeping the car on when cold.
do you think is the temperature sensor or what can cause this problem?

Got an Auto-Scan?

Use VCDS to monitor the temperature sensor. Let car sit overnight and assume ambient temperature. Check coolant temperature before starting car. Is it within a few degrees of actual ambient temperature? Start car. Watch (or better yet, log) temperature rise. Is it reasonable?
