Hello everyone, at about 1500Umin, when accelerating, a vibration from the dashboard occurs for a short time. I can’t get places from where it comes from. My experiments were already: center console & car radio removed and held everywhere and obeyed, but no change can be detected or located. Vibration still available. Furthermore, the windscreen wiper cover is removed to get to the 4 screws that hold a large part of the armature. These screws pulled after, no difference, unfortunately. Now I’m perplexed. Can anyone else help me? Is there any such thing as technician bulletin or secret tips that only the friendly one knows? Thank you, Mario Volvo, BJ2000, 200Tkm, gasoline, 140PS
