On the E90, LH_UND_NSW_NICHT_GLEICHZ governs the fog lights going out when the high beam is flashed, while a separate parameter, FL_UND_NSW_NICHT_GLEICHZ, covers a continuously lit high beam.
On the E90, holding the fob lock button to close the windows and sunroof is enabled by setting KOMFORTSCHLIESSUNG_FB in the CAS module. Model years, steps and how to revert.
On the E90, having the key fob pushed out of its slot when you shut the engine down is enabled by KOMFORT_EJECT in the CAS module. It needs the start/stop button held two seconds longer.
On the E90, whether the doors unlock by themselves when the engine is stopped and the key is pulled is governed by ER_KEYOUT_AUTOVR in the CAS module.
On the E90, enabling daytime running lights, choosing which lamp acts as the DRL, or disabling the function entirely is done with the TAGFAHRLICHT and DRL parameters in the FRM/NFRM module.
On the E90, showing instant fuel consumption as a number in the cluster is enabled with DIGITAL_KVA in the KOMBI module. It is marked for every model year.
P0710 identifies Transmission Fluid Temperature Sensor A Circuit Malfunction. Diagnosis compares transmission fluid temperature, coolant and ambient cold-soak values, sensor voltage, gear, converter slip, and connector movement so its electrical, control, and physical causes are separated before repair.
P0701 identifies Transmission Control System Range or Performance. Diagnosis compares complete EGS fault memory, requested and actual gear, turbine and output speeds, pressure commands, fluid temperature, and voltage so its electrical, control, and physical causes are separated before repair.
P0641 identifies Sensor Reference Voltage A Circuit Open. Diagnosis compares reference A voltage, affected sensor values, module supply, ground quality, branch isolation, and harness movement so its electrical, control, and physical causes are separated before repair.
P0638 identifies Throttle Actuator Control Range or Performance Bank 1. Diagnosis compares throttle target, both position tracks, actuator current, pedal tracks, intake pressure, and battery voltage so its electrical, control, and physical causes are separated before repair.
P0501 identifies Vehicle Speed Sensor A Range or Performance. Diagnosis compares all wheel-speed traces, DSC vehicle speed, DME road speed, KOMBI display, steering angle, and network faults so its electrical, control, and physical causes are separated before repair.
P0409 identifies EGR Sensor A Circuit Malfunction. Diagnosis compares EGR command, position feedback, MAF displacement, MAP response, reference voltage, and connector movement so its electrical, control, and physical causes are separated before repair.
