  1. A4 engine rattle at idle

    General A4, RS4, and S4 Discussion
    We have a 2005 A4 1.8 automatic that has a rattle when it is idling in gear. It comes from the area of the belt tensioner and you can see the tensioner vibrating back and forth as it keeps the proper tension on the belt. We have had it repaired at a general repair shop and an Audi "expert"...
