After my CS passed the initial 2000-mile period, I started revving the engine to higher speed: close to or pass 4000rpm. Slowly I observed the issue shown in my video below. Gear indicator starts flickering around 4000rpm. When it is not flickering, I also realize rev matching is not functioning in both Sport and Sport Plus mode. Anyone had seen similar issue in any of the Porsche before? I will bring the car to the dealer in 2 weeks. Meanwhile, just want to know what could potentially be the cause of this issue.
