uneven start problems 99er 2.5T petrol

Hey all V 70 one fans, I greet you!! Drive now for 11 years V70 and want nothing else more. Currently: 3 x 2.5 T 97er and GAS, and in the hands of friends 1x 2.5 T 99er gasolineerFreue me for exchange with you. The 99er petroler has a very special star problem: He always runs on , but quite differently bad! To zero degrees around very bad in the morning, then when he has run times he starts a little better. In the summer he starts sloppy , and when he is then warm / hot , then it’s really bad with the start. Up to thirty times the start attempt possibly, BUT THEN WHEN HE LEARNS THROUGH HE ALWAYS NEEDS LIKE. This one of all four has the best agility “in my care “. Have tried a lot over the years that this already goes on. Until the exchange of the ECU , all relevant sensors, injection rail overtakes, ignition coils, spark plugs ……… .. Greetings the Günter, at home in 89264.
