Not sure this is in the right area, so if not can someone move it for me please?
Collected my Astra Coupe on Tuesday, which is a great car and I love it, but when im slowing down (IE - Taking foot off the throtle, and rolling a little rather than braking) there is the most hourendous drumming sound It sounds exactly like when your driving on the motorway and you go onto the hard shoulder over them raised bumps on the white lines.
At first I thought it might be just because the car hadn't been driven for a while, but its still doing it this morning and its getting louder by the day.
Anyone any ideas as to what could be causing it? My first thought is the tyre pressure is wrong, or becuase the tyres are new it might be that
Anyone experienced this before? Any help would be greatly appreciated
