OVERVIEW
Genuine VW/Audi Powertrain Mount Bolt
N-905-970-05 is the original M10 x 70 x 32 fastener for the assigned engine or transmission mounting attachment. The same OEM number serves different mounting positions across the listed vehicles. Match the complete number and the mounting diagram before ordering; vehicle fitment does not make this bolt interchangeable with every fastener on the mount.
Technical details
- OEM reference: N-905-970-05 / N90597005.
- Published nominal size: M10 x 70 x 32.
- Collared hex-head fastener for a specified powertrain mounting connection.
- One individual bolt supplied. Mounts, brackets, washers and other hardware are separate.
- The fitment table identifies the confirmed engine, gearbox and attachment restrictions.
Powertrain mounts locate the engine and transmission while their rubber or hydraulic elements manage movement. The mounting bolts hold the assigned bracket or mount against its mating surface. Correct length, collar geometry and engagement matter: a similar bolt may bottom out, engage too little thread or clamp the wrong surfaces. This fastener does not replace a worn mount or repair damaged receiving threads.
Common reasons to replace
Replace hardware with stripped threads, a rounded drive, corrosion, bending or other visible damage. Renew the bolt when the applicable workshop procedure identifies it as single use, including procedures involving angle tightening. Replacement is also appropriate when a previous repair installed an incorrect fastener or the original bolt is missing. Inspect the mount and bracket for separation, cracked rubber, leaking hydraulic fluid where applicable, elongated holes and contact damage. A clunk or excessive engine movement can have several causes and should be diagnosed before selecting parts.
Installation and service notes
Support the powertrain using the specified workshop equipment before releasing a mounting connection. Identify the exact mounting position, check the mating surfaces and receiving threads, and align the mount without pulling it into place with the bolt. Follow the vehicle-specific tightening sequence, replacement requirements, torque and angle values; no universal tightening value is assigned across these applications. Use the specified clean, lubricated or locking-compound condition from the repair procedure. After assembly, confirm mount alignment and clearance and inspect the connection during the prescribed post-repair check.
