The error appears only on cold starts or after the car sits overnight. It may clear after driving for 10 minutes. 2. Failing Throttle Pedal Position Sensor (Pedal Value Sensor) The accelerator pedal in BMWs has two redundant sensors. If the values from sensor 1 and sensor 2 don't match (plausibility error), the DME interprets this as an unsafe driver request and activates torque limitation.
using BMW ISTA (factory software) or a high-end scanner like Autel MaxiCOM or Foxwell NT510. Generic OBD2 readers will not show D52C44 properly.
Error D52C44 accompanied by codes like CDB704 or D01619 (pedal sensor ranges). 3. DSC (Dynamic Stability Control) Sensor Misfire The DSC module sends torque reduction requests to the DME during cornering, braking, or wheel slip. If the DSC yaw rate sensor, steering angle sensor, or brake pressure sensor gives erratic data (e.g., due to a failing DSC pump or hydraulic unit), the DME triggers D52C44 as a fail-safe.
– Look at battery voltage at the time of fault. If voltage is below 12.0V, start with the battery (charger or replacement).
Shifting feels clunky; error occurs specifically during 1-2 or 2-3 gear changes. 5. Software Incompatibility (Especially After Tuning) If you have installed a piggyback tune (e.g., JB4, RaceChip) or a flash tune (Bootmod3, MHD), you may have altered the torque model. The DME sees torque values that exceed its internal plausibility thresholds and throws D52C44. Similarly, if your DME software is outdated (pre-recall version), a BMW factory update is needed.
