So I bought a new-old (less than a year old) Fabia III the other day and I'm loving it so far -- except for these 2 different high pitched sounds that come from the engine (?) when your foot is on the gas.   Please have a listen here:   1. https://vid.me/GS2G 2. https://vid.me/TKgS   In video 1 you can hear it clearly, while in video 2 you may want to turn up your volume a bit louder. There are 2 different kinds of sound, the 1st one is something like a high-pitched "t-t-t-t-t-t-t-t-t" so
