OVERVIEW
Genuine bolt for the original Multitronic valve-body assembly
The N-104-551-01 Genuine VW/Audi bolt secures the assigned valve-body and oil-pump assembly position in the specified Multitronic CVT configurations below. Its M6×70×37 factory specification identifies the correct fastener for that attachment.
The CVT assembly uses similar-looking bolts with different lengths and shank arrangements. This bolt is distinct from N-104-550-01, which carries an M6×90×37 specification. Match the complete number and original position before reassembly.
Technical details
- Complete factory number: N-104-551-01.
- Factory specification: M6 × 70 × 37.
- Design: combination hexagon-head bolt with the original extended shank/pin arrangement.
- Quantity supplied: one individual bolt.
The full catalog specification is important to the mounting geometry and thread engagement. It does not establish interchangeability with a conventional M6 bolt or hardware from a different automatic transmission.
Common reasons to replace
- The original valve-body mounting bolt is missing during service.
- Threads are damaged or cross-threaded.
- The drive head or bearing surface is damaged.
- The shank or locating section is distorted.
- The factory CVT service procedure requires a replacement bolt.
Inspect the receiving threads and valve-body mounting surfaces using the factory service procedure. A new bolt cannot correct hydraulic wear, electronic control faults or a damaged transmission housing. Diagnose transmission symptoms separately.

Installation guidance
Follow the factory CVT valve-body procedure with the prescribed cleanliness controls and support methods. Keep contamination out of the hydraulic assembly, place each bolt in its assigned position and apply the exact tightening sequence and specification.
Complete the required CVT fluid-level, leak, diagnostic and adaptation procedures for the repair performed. Do not transfer torque values from a different-length valve-body bolt or another gearbox.
Ordering information
Supplied as one genuine bolt. Valve body, oil pump, seals, fluid, electronics and a complete hardware kit are not included. Confirm the installed gearbox and original bolt position before ordering.
