Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Leading evidence: 'Set point' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Set point' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

O2 sensor heater, function NOTE The function checks the sensor temperature (by measuring the internal resistance of the Nernst cell) depending on the exhaust temperature. This can be used to discover discrepancies between the set point and actual temperature of the O2 sensor, from which a faulty heating control can be deduced. If the DME has detected a vehicle voltage > 16 V, fuel trim is also interrupted. Diagnostic conditions DME control unit power supply voltage (DME) 10 V … 16 V Exhaust temperature 300 °C (572 °F) ... 600 °C (1,112 °F) Time after engine starts > 200 s Intake air temperature > -7 °C (19 °F) No overrun No other driver fault of O2 sensor heater Possible fault causes Vehicle voltage > 16 V Connector corrosion Contact resistance in the lines O2 sensor faulty DME control unit faulty
