9-3 2.2 Tid

Hello, need urgent help or tips! My 9-3 2.2 TID has now stayed in a short time twice or has jumped and then gone out again. The first time a Saab branch could “reset” the car again, but now he and they are “mine”, it would be the injection system. The first time they said that an old software is the problem, which was wrongly played up by another Saab workshop at the end of last year. After I complained, s If anyone knows this problem or has a tip for me, super1 Thank you, your Ollikaf.
