I created a video showing better the noise I get in the superb 2020 model 1.5 TSI with MT 6s. For those that says here the noises are normal, I dare to totally disagree if those noises are same as in the video I posted. You don't hear this type of noise if you drive with your windows closed. While the dealer agreed that there is a noise, the outcome of their check was that its "characteristic" and normal.
I asked to check another 1.5 TSI with 6s MT car (which happened to be an octavia) and the same type of noises are there present as well. To me it looks that these are some mishaps in the engine rev management control that are affecting the clutch and/or the MT, most probably as some side effect of the fixes they did for 1.5 TSI engines (https://www.honestjohn.co.uk/news/new-cars/2020-03/volkswagen-announces-fix-for-15-tsi-engine-hesitation-issues/). These kind of noises cannot finish well for your transmission (at least) in a longer run. Getting your transmission broken in 2 years (after warranty) is a perspective that I'm not pleased with at all.
