Hello all, I wish you all a happy, healthy and puncture-free new year. I am Saab newcomer, recently bought me a Saab 9000 2.3 Turbo CS BJ 1992. A great car, inside and outside perfectly maintained, no rust, stitching and a silk-soft running engine with automatic transmission. Yesterday evening lit up in the display CHECK OIL LEVEL. So to the next gas station, to measure oil level. The oil level was still short over MIN, so some oil was refilled, De The oil rod shows the stand exactly in the middle between MIN and MAX, so too much is not in it.The starter turned, but the engine didn’t jump any more. At a glance under the bonnet I found a hose that had loosened (see appendix), but nothing changed at the start. The pointer of the turbo indicator has been in the middle since then, even if the car is out. ADAC Mann jammed the battery to reset the on-board computer, since he suspected the error there, but did not bring anything, except that now lights up in the info display when starting ANTI LOCK. Can anyone explain this error? Thank you for your help. Christian
