Adaptations And Equipment Variations: Notes

Adaptations enable automatic adaptations of parameters in the engine control unit software. As a result, engine control automatically adapts the component tolerances or adapts the values in the system. Equipment specifications are also taught-in using messages or actuation commands during the first start-up.

The "Reset all adaptation values" service function resets all adaptation values in the engine control unit to their original condition. A replaced teach-in of the values is carried out upon terminal change, engine running, partial load operation or full load operation, depending on the adaptation.

Resetting the variants that have been taught in means the equipment specifications are once again taught-in upon the next terminal change. In this process, engine control units independently learn whether actuators or control units have been installed and which equipment specification they are dealing with. An example would be the electrical exhaust flap or a trailer tow hitch. The system must be trouble-free to correctly teach-in the variants.

The VANOS adaptation values must be reset after having worked on the VANOS adjuster, crankshaft, camshaft or timing chain.

Reset the minimum quantity adaptation after having replaced the injectors.
