P1536



Diagnosis information - Control unit DME (DFI)



Activation Oil pump



INFORMATION



- The measured oil pressure is compared with the setpoint oil pressure.



- The setpoint oil pressure depends, among other things, on the ambient conditions (temperatures, off time, etc), operating point of the engine...



- A fault is detected if the PWM signal is outside a defined range for > 30 seconds.



Diagnostic conditions



- Engine running



Possible fault causes



- Dynamic driving style when oil level is near minimum (oil foaming)



- Engine oil pressure too low (Oil level, Oil quality, Oil dilution, Soiling Oil circuit, Oil circuit Faulty - increased leakage inside the engine)



- Engine oil pressure too high (Oil quality, Oil thickening, Soiling Oil circuit, Oil circuit Faulty)



- Oil pressure sensor Faulty (incorrectly trimmed)



- Oil pressure control valve Faulty



- Oil pump Faulty

P1538



Diagnosis information - Control unit DME (DFI)



Activation Oil pump



INFORMATION



- The oil pressure-regulating valve is controlled via a PWM signal.



- The PWM signal depends, among other things, on the ambient conditions (temperatures, off time, etc), operating point of the engine (rpm,



load, oil temperature), measured oil pressure (at the oil pressure sensor)...



- A fault is detected if the PWM signal is outside a defined range for > 8 seconds.



Diagnostic conditions



- Engine running



Possible fault causes



- Engine oil pressure too low (Oil level, Oil quality, Oil dilution, Soiling Oil circuit, Oil circuit Faulty)



- Engine oil pressure too high (Oil quality, Oil thickening, Soiling Oil circuit, Oil circuit Faulty)



- Oil pressure sensor Faulty



- Oil pressure control valve Faulty



- Oil pump Faulty
