2008 Saab 9-3 Linear 4 Cyl 2.00L
Vibrations and sound during idle.
Hi, I need help with my 2008 SAAB 9-3 Sedan (B207E engine). Every now and then I can feel vibrations and hear sounds coming from the floorboard area. It sometimes come whenever the car is idle on P and D with the footbrake. The vibrations and sound completely go away when I turn off the aircon (in P or D with footbrake) or slowly goes away with the aircon turned on when the car is moving off. This issue started after I sent the car in the workshop to get the aircon refrigerant leak fixed and the rear crankshaft oil seal replaced.
Many possibilities; a/c hoses or rigid lines routed incorrectly, exhaust system touching / rubbing the chassis, wiring harness routed incorrectly - to list only a few.
