Hello dear Saab community, on Saturday I was with my new acquisition from April, 900/II Cabrio BJ 95, 2,3 SE Automatic in the next SAAB center, because occasionally the engine is “smoothed” when I insert a driving stage. In addition, the idle speed varies sometimes, and the consumption of 11.5 – 12 liters without running air conditioning with restrained driving mode, mostly still over land, seems too high, according to what I read here. The error memory has stored above all diagnosis. As a vehicle I have a used car warranty (BMW dealer) , so far they had found nothing (allegedly?) but had hit an ASU as a test. With the search function I found nothing usable here in the forum. But the friendly Saab screwdriver made the impression that this was not unusual, unfortunately I was in time (and thought I had found more here). Is there the camshaft sensor in addition or instead of a crankshaft sensor? Think the error picture k Can fit. Does the engine management run into an emergency run program when the sensor fails? And automatically out when it returns? What may an exchange cost? Where does it sit exactly? I would like to mark it before I bring the car into the workshop. And with some background knowledge it negotiates more easily. Many questions. Think, few can answer. Bet, the hangover knows something about it; gell, Chris? Thank you and love! Jörg
