I have a 2001 VW Passat if it's warm or cold it tends not to start . I could drive it to the store and parked it come out 15 minutes later it might start with no problem or not or I could drive it 5 different places and it'll start every time . Some mornings it starts right up other times it hesitates have to keep trying and then it starts if lucky. It is a toss up ! Could be cold or hot weather not started for a day or drove off and on all day, you never know if you are going to go or not. It is never the same saturation. HELP!
