Hello, I have an Insignia B Sports Tourer D20DTH (2019). I drove approx. 100,000 km. I bought it with a mileage of 90,000 km. The problem I have is that since I bought it, the car whistles quite loudly just when accelerating (from cca. 1800 RPM to 2700 RPM) in any gear, but the car drives without problems, the performance is fine and it does not show any errors. Is it normal for these cars to have a louder whistle noise? The whistling has a high pitch sound. ​​​​ In an Insignia A (A20DTE) with over 350,000 km, I have a quiet turbo and engine compared to this one. Thank you.😊

My turbo is also whistling but I like it, I can only hear it when the windows are down.
