Hello Saabgemeinde, according to LiMa, Agr-Ventil, diesel pump now follows the next stroke (within 6 months). Perhaps one of you knows this problem….. During the undertouring acceleration (~1800 rpm) the “Check Engine” lamp starts. The error is stored in the control unit because I can not delete it by “battery disconnecting”. In the error memory (read out with Bosch) is then: altitude sensor, suction tube pressure sensor P0106. In this connection (??) I had last year at Übe At the highest point the car started to jerk – I gave it full throttle was the jerking away. On the Italian side then the miraculous healing: no more jerking…. On the way back in place (highest point) again the same problem. Saab on suspicion then changed the air quantity meter. Somehow I have the feeling that it could also be the AGR valve (had installed a used one a few months ago. Thanks already in advance for your feedback Bummerl
