Use the correct multipoint tool for the actual drive.

On the listed Audi RS5 applications, it belongs to the alternator and mounting-bracket arrangement. On the first-generation R8 configuration below, it secures the assigned rear anti-roll-bar clamp attachment.\u003c\/p\u003e\u003cp\u003eThese are separate joints with separate service procedures. The same part number does not make their tightening values, required quantities or access procedures interchangeable.
