Hello together, during my last visit to the workshop I called for drones or resonances in the range 2600 – 2800 rpm. I noticed this especially when driving at 140 km/h, because then the engine touches this Drrehnumber range. I know another D5 driver (also XC70) who has this problem. My workshop also noticed the resonances (should be area exhaust gas), but could not circle the error so far because of lack of documentation. But wants to make an effort for information. experience my question: does someone know the problem and has it been solved in the affirmative and how ? For answers already before thank you
