Hab eben den Fehlerspeicher ausgelesen:

Fehler 15 Lamdasonde vorderer Block inactivation error

Fault Description
Inactivation errors 15 (left) & 23 (right) indicate the sensor never "woke up" from cold. Cold sensors produce little or no output voltage. Once the engine RPM exceeds 1500RPM, the PCME expects to see the voltage on the sensor(s) go above 500mV within 100 seconds. If it does not, the inactivation code gets set.
Inversion errors 17 (left) and 24 (right) occur when the sensor stops responding to the PCMEs adjustments to the A/F ratio. Inversion refers to the sensor swinging back and forth (or inverting) across 500mV as the PCME alternately makes the A/F ratio slightly richer or slightly leaner. If the sensor does not mirror theses changes, the PCME will set the inversion code.

Also heißt Lambda im Toleranzbereich doch nicht, dass die Lambdasonden nicht fehlerhaft sind.
