Contact point detection (F13 MTA/F17+ MTA)

Note:   The contact point is the position at which the thrust plate and the clutch disc touch and transfer a small torque (approx. 4 Nm ). The control unit is despatched with a preset contact point. This characteristic value varies as a consequence of clutch and vehicle tolerances. Therefore this parameter must be determined when the vehicle is first used.

Not OK Criterion after Determining the Contact Point

After determining the contact point with TECH 2 it is essential to assess whether the start-up procedure was successful. The following not OK criterion is applicable:

  • Vehicle type, after determining contact point 2
  • Z16XEP contact point >14.0 mm

If the Not OK criterion is exceeded after the 2nd contact detection point it is necessary to repeat the filling/bleeding process and contact point detection. Fluctuating engine torque signals or air in the hydraulic line of the release system can cause this type of error. Increased clutch temperature has a negative influence on contact point determination or indicates defective contact point determination.
