Diagnostic information - DME (DFI)

Oil pressure control limit value

NOTE:
- The measured oil pressure is compared with the setpoint oil pressure.
- Among other things, the setpoint oil pressure depends on:
- Ambient conditions (temperatures, off period etc.)
- Engine operating point (rpm , Load , Oil temperature ,...)

- A fault is detected if the measured oil pressure is outside a defined range for more than 30 seconds.

Diagnostic conditions
- Engine running

Possible fault causes
- increased leakage inside the engine
- Oil pressure too low
(oil level, Oil quality, oil dilution, dirt in oil circuit, oil circuit faulty)
- Oil pressure too high
(Oil quality, oil thickening, dirt in oil circuit, oil circuit faulty)
- Oil pressure sensor faulty (incorrectly trimmed)
- Oil pressure-regulating valve faulty
- Oil pump faulty
