OVERVIEW
N-912-225-01 Genuine VW/Audi Upper Shock Absorber Mounting Bolt - M10 x 40 mm. This Genuine VW/Audi fastener secures the assigned upper shock absorber mounting connection. The mounting joint holds the shock assembly in its designed position while suspension movement loads the connection. Matching the correct bolt and the vehicle's mounting arrangement is essential when replacing a shock or servicing its upper mount.

Common reasons to replace
A new bolt is required when this specified fastener is removed during shock absorber or upper mount service. Replace hardware with damaged threads, a distorted seating area, corrosion affecting the connection or a rounded hex head. A loose or damaged mounting connection warrants inspection of the bolt, mount and mating threads rather than simply tightening an unknown used fastener.
Installation and service notes
Support the suspension assembly as directed by the vehicle repair procedure before releasing its mounting hardware. Inspect the mounting holes and mating threads, compare the new fastener with the specified part number, and install it in the factory-assigned position. Follow the prescribed suspension support position and tightening procedure; this listing does not substitute a generic torque value for the repair manual.
A new bolt does not correct a torn mount, damaged bearing, elongated mounting hole or stripped mating thread. Inspect those components separately and replace any other single-use hardware required by the repair. Confirm the suspension equipment and mounting diagram before ordering; the same vehicle may use different fasteners at its lower mount and other suspension joints.
