Affected Vehicles



Condition



MIL on. One or several of the following DTCs for the cam actuators are stored in ECM memory:



P11A2 cam actuator "A" cylinder 1: implausible signal



P11A4 cam actuator "B" cylinder 1: implausible signal



P11A6 cam actuator "A" cylinder 2 implausible signal



P11A8 cam actuator "B" cylinder 2: implausible signal



P11AA cam actuator "A" cylinder 3: implausible signal



P11AC cam actuator "B" cylinder 3: implausible signal



P11AE cam actuator "A" cylinder 4: implausible signal



P11B0 cam actuator "B" cylinder 4: implausible signal



P11B2 cam actuator "A" cylinder 5: implausible signal



29



P11B4 cam actuator "B" cylinder 5: implausible signal



P11B6 cam actuator "A" cylinder 6: implausible signal



P11B8 cam actuator "B" cylinder 6: implausible signal



Technical Background



After the activation of the cam actuator to change to the other cam profile, the pin of the actuator is pushed back in by the cam. This is confirmed by



a voltage impulse, which is registered by the engine control unit and confirms the operation. If this does not happen, or not at the right time, a DTC



"implausible signal" is saved in ECM memory.



Check the distance of the pin tip of the cam actuator for valve lift system to the camshaft when it is not operated with a gauge. The measurement of



the tip to the basic camshaft circle outside of the groove must be taken, see Figures 1-3 below.

If this measurement is 0.9mm, the actuator 06E103697J must be installed.



Note:



The actuator 06E103697J must only be used, if the measurement is 0.9mm or bigger.
