Controller displays F29 – Oil level low alarm (separate from pressure)

Safety first: Shut down the engine and allow oil to drain back to the sump before checking level.

• Check oil level: Use the dipstick to verify oil level. Add MTU-approved oil if below the minimum mark.
• Inspect for leaks: Look for oil around the pan gasket, seals, filters, and external lines. Repair leaks before returning to service.
• Sensor check: Inspect the oil level sensor and wiring. Test its operation according to MTU specifications and replace if faulty.
• Monitor consumption: Track oil usage over several run hours. Excessive consumption may indicate internal engine wear requiring professional evaluation.
• Clear alarm: After correcting the level and any leaks, clear the F29 alarm and test run the generator.
