To install:

  1. Replace sealing ring between throttle body and intake manifold.
    A faulty throttle adjusts the adaptation values stored in the DME control unit. These adaptation values must be reset after the throttle assembly has been replaced.

  3. The installation continues in the reverse of the removal procedure.
