Strange, Weird sound

[PTNoob01695]

Hi guys

I've noticed a strange vibrating/bzzzzzz noise whilst accelerating/decelerating and turning at roundabouts etc. im really not sure what causes it though. Has anyone experienced anything like this. Sorry i cant be more specific

Thanks for any help you can give

did it only happen when you get hard on it? I mean like accelerating very hard, braking the most you can or turning at a point that when you hit the littelest crack in the tarmac the rear slide a bit.

if so you I would blame it on the tires, when I changed from the stock 15 inches wheels and all season tires to 17 inches wheels and sport summer tires I noticed a lot less vibrations under hard conditions

or another time I notice some vibrations is when I accelerate at 700-1300rpm, which most cars that can do it does

To help narrow it down, see if you can isolate between engine and drivetrain.
Find out where you can make the noise happen, look at your tachometer to see the engine speed. Put the vehicle in neutral and see if the noise goes away when the engine speed drops.
Then rev the engine in neutral to the same speed to see if the the noise comes back.
