Hi

Just bought my fabia vrs but there is a droning sound as soon as I get to 20 mph gets louder accelerating and slowing down louder at low speeds think it may be the the tyres even though they look fairly new thought it was the bearings but think there ok drives smooth enough also the pipe for the turbo popped off not the best start but you have to spend a little as it is ten years old hope someone can help thanks.

Very possible your tyres could be "stepped" makes a sound VERY like a dead wheel bearing. 

 

What I'd suggest as a cheap fix would be to swap your front wheels to the rear and vice versa, take the car for a drive and see if the noise persists. 

 

I had this when I 1st bought my Fabia with Nokian tyres, they looked ok but the leading edge of each ruber block was about 1mm lower than the trailing edge making a saw blade or step type pattern which causes the noise. 

 

New tyres and it was sorted
