147 TS 2.0L - Engine whistle/whining when throttle applied
Hi, i tried a search but found no results the same so here it goes...
Im new to the forum and have just bought a 147TS Lusso 53' plate. drove it 300miles today and noticed that when throttle is applied between 70/80mph it has a loud whistling noise (loud enough to hear over the bose speakers with the windows up) coming from the engine. the noise will be more prominent the the more you apply the throttle until a point in which it will disappear. over 80mph its gone, below 70mph it goes too. if i select cruise control in this range i get the sound constantly. Im a bit concered and was hoping to get some insight into what could be causing this.
any help would be appreciated??
