Annoying sound - suspension
When I am driving on a rough road (slow speed), my car (alfa 147) is making extremely annoying noises. I think it's coming from the suspension. You can hear it in the front and in the rear. You can only hear it when the car has driven for more than 15 minutes and when it's warm weather. Is there anybody who knows what the problem is?
The car is one year old and has 37000 km.
Please give some advise. I already went to the garage, but they couldn't find anything.
