    Hi I have a 2012 plate Astra 2.0CDTI and there is a humming sound coming from the engine. This however only happens when the vehicle is warmed up and tends to happen when im at traffic lights. It humms like hell. When I press accelerator slightly then it stops! I took it to garage first time...
