Who knows these sounds???

Hello all! My Laguna III 2.0 140hp EZ 2010, gives some annoying sounds of itself and I don’t mean the flapping 😉 . When driving e.g. in 5 or 6 gears, so between 1700 and 2000 turns it always comes to a beep or whistle noise, can that come from the gearbox? Have read something similar here in the forum, where the workshop probably thought that this was normal… Then a loud beep comes out of the engine compartment (possibly the alternator) as soon as you get the key card one Is especially good to hear when there is little surrounding noise, e.g. in the underground garage it makes nice loud piiieeeeep. Besides, I feel the “servo noises” extremely loud. Especially in the city, when you drive (due to congestion) slowly and steer, it does constantly sssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss,,,,,,,,,,, gt. I look forward to your information and experiences!
