Determining the contact point (F13+ 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 contact point determination

After determining contact point using TECH2, an evaluation must be undertaken as to whether initial use was successful. The following not OK criterion applies:

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

If heh not OK criterion is exceeded after contact point determination 2, toping up/bleeding and contact point determination must be repeated once only. Fluctuating engine torque signals or air in the hydraulic lines of the release system can lead to this error profile. This not OK criterion is obtained empirically by means of production data evaluation and is similarly implemented in production plants. Increased coolant temperature negatively affects contact point determination or is evidence of incorrect contact point determination. After repairing and starting up the MTA system:

  Remove

1.   Connect TECH 2 Note:   Determining the contact point may be interrupted. The reason for the interruption is displayed in the TECH 2 display. Save the test instructions for a remedy. 2.   Perform procedure for determining contact point Select corresponding vehicle identification Select "Transmission" in the "System Selection" menu Select vehicle identifications "Easytronic (MTA)" Select "Additional functions" Select "Determination of contact point" Follow the continued menu system of TECH 2 3.   Comply with the start-up routines required
