Hi everyone, new to owning a Seat and new to this forum, I was hoping someone could put my mind at rest with something i noticed about my new to me car, Its a 2021 Leon 1.5 TSI Evo and i have noticed, usualy in 2nd or 3rd i can here a quite loud 'chick' sound when the car enters or exits 'ECO' mode, has anyone else noticed this? or should i be worried, TIA all

Normal. It's the sound of it engaging ACT and running on just two cylinders, the engine then sounds like a cheap sewing machine if you have the windows open.

HA, yeah sewing machine , was worried as i can hear the quite loud click of it activating AND deactivating 2 cylinders, i got new car 'knockanoia' and the more i listen the more i hear and the louder the noises get, thanks for the reply
