BMW E90 N46 Pressure Plate Torque Specs: 25 Nm or 34 Nm for M8 Bolts

User question

hi, what is the torque setting on a bmw e90 n46 pressure plate

Artificial Intelligence Response

Direct answer to the question

For a BMW E90 with the N46 engine, the clutch pressure plate-to-flywheel torque depends on the bolt type BMW fitted:

• M8, property class 8.8: 25 Nm
• M8, property class 10.9: 34 Nm
• If it uses ZNS torque-angle bolts: 15 Nm + 90° (±5°)

However, on the E90 320i N46 TIS page, the N46 itself is listed under the 25 Nm / 34 Nm bolt-grade specs, while the 15 Nm + 90° ZNS spec is listed for a different engine group that includes N46T, N43, N52, etc. So for an N46 (not N46T), the usual spec is 25 Nm or 34 Nm depending on whether the bolts are 8.8 or 10.9. BMW also says to replace the screws. (workshop-manuals.com)

Detailed problem analysis

BMW’s clutch torque table for the E90/N46 distinguishes the pressure-plate fasteners by fastener class and fastening method, not by a single universal number. That is why different answers online quote 25 Nm, 34 Nm, or 15 Nm + 90°. They are not necessarily contradictory; they correspond to different bolt specifications. On the E90 320i N46 clutch torque page, BMW TIS explicitly lists:

• M8 8.8 → 25 Nm
• M8 10.9 → 34 Nm
• a separate ZNS-bolt torque-angle procedure, but that engine list names N46T, not N46. (workshop-manuals.com)

Current information and trends

The most reliable source I found is the BMW TIS-derived workshop material for the E90 320i (N46) and the BMW group torque standard extract. Both agree that the base clutch-to-flywheel values are 25 Nm for M8 8.8 and 34 Nm for M8 10.9, with new screws required. (workshop-manuals.com)

Supporting explanations and details

Your N46 clutch is a SAC (self-adjusting clutch) type in BMW repair documentation. BMW’s repair procedure says the clutch disc must be centered with the specified tool, the clutch must locate on the dowel pins, and the locking element/piece must not be removed until the clutch is screwed down. BMW also states that the screws must be replaced and that torque/angle instructions must be followed exactly where applicable. (workshop-manuals.com)

Practical guidelines

If you are standing at the bench and just need the number:

• If your pressure-plate bolts are marked 8.8: use 25 Nm
• If they are marked 10.9: use 34 Nm
• If you have BMW ZNS torque-angle bolts for an engine/application that calls for them: use 15 Nm + 90° and replace them (workshop-manuals.com)

Possible disclaimers or additional notes

If your car is actually an N46T/N46N or the clutch kit includes a different bolt set than what came out, use the spec that matches the actual supplied bolts and BMW procedure for that exact application, not the old torque value by assumption. (workshop-manuals.com)

Brief summary

For a BMW E90 N46 pressure plate, the safest answer is:

Pressure plate to flywheel:

• 25 Nm for M8 8.8
• 34 Nm for M8 10.9
• 15 Nm + 90° only if it specifically uses the ZNS torque-angle bolt setup; that torque-angle listing is associated with other engine groups such as N46T, not the plain N46 on the TIS page. (workshop-manuals.com)

If you want, send me your VIN last 7 or a photo of one pressure-plate bolt head, and I will narrow it to the exact one.
