VW New Beetle knocking rear noise - arnold2
1.6 New Beetle, there is an odd knocking noise from the rear, noticeable during acceleration (engine past about 2,000 rpm), or during braking, or over rough surfaces ? Had a mechanic check the exhust, which was OK - I\'m wondering if the exhaust is out of alignment and knocking on the suspension. Kind of sounds like mice with small hammers ! The noise goes once you\'re cruising ....
