Q: What does code P1615 mean?

Engine Oil Temperature Sensor Circuit Range Performance. P1615 on Volkswagen vehicles means the engine control module (ECM) has detected that the engine oil temperature sensor signal is outside the expected range or is not behaving rationally compared to other temperature inputs. The ECM uses this sensor to protect the engine during cold starts and high-load conditions, so it flags the fault when the voltage or calculated temperature does not match the model's predicted values.
