What to do if MTU Engine speed is not steady?
If the speed of your MTU Engine is not steady, it could be due to a faulty injector, a faulty speed transmitter, or a faulty Engine Control Unit. To resolve this, replace the injector, check and replace the speed transmitter as necessary, check the plug connections, replace the Engine Control Unit, or contact Service.
Why MTU Engine does not reach nominal speed?
If your MTU Engine does not reach nominal speed, it could be due to excessive load, a clogged air filter, a clogged fuel prefilter, a clogged easy-change fuel filter, faulty engine wiring, a faulty injector, or excessive exhaust back pressure. To address this, reduce the load, check the signal ring position of the service indicator, replace the air filter, drain the fuel prefilter, replace the fuel filter element, check the engine wiring, replace the injector, or check the SCR system. If problems persist, contact Service.
What causes MTU Engine to fire unevenly?
If your MTU Engine is firing unevenly, it could be due to faulty engine wiring, a faulty injector, or a faulty Engine Control Unit. To address this, check the engine wiring, replace the injector, or replace the Engine Control Unit. If problems persist, contact Service.
Why MTU Engine turns on starting, but does not fire?
If your MTU Engine turns on starting but does not fire, it could be due to poor rotation by the starter because of a low or faulty battery, faulty engine wiring, or a faulty Engine Control Unit. To resolve this, charge or replace the battery and check the engine wiring. If those steps don't work, replace the Engine Control Unit, or contact Service.
What to do if MTU Engine does not turn when starter is actuated?
If your MTU Engine does not turn when the starter is activated, it could be due to several reasons: a low or faulty battery, faulty cable connections, issues with the engine wiring, loose assemblies or connectors on the LOP, loose plug-in connections on the Engine Control Unit or Engine Interface Module (EIM), a faulty fuse F1 in the engine wiring harness, or a blocked running gear. To resolve this, charge or replace the battery, ensure cable connections are secure, check the engine wiring, visually inspect the assemblies, and check the plug connections on the Engine Control Unit and Engine Interface Module. Also, inspect the fuse and replace it if necessary. If the running gear is blocked, contact Service.
What to do if the MTU 16V4000M73L Engine has a water alarm?
If the maximum water level is reached, the water level electrode opens the water drain valve, discharging water. If the valve's opening time exceeds 4 minutes, the pump shuts off and triggers an alarm. To address this, press the illuminated 'Water alarm' button to acknowledge the alarm. You can also manually drain the water by pressing the illuminated 'Water drain' button, which opens the water drain valve.
What to do if the MTU Engine has white exhaust gas?
White exhaust gas could mean the engine isn't at operating temperature or the intercooler is leaky. Run the engine to reach operating temperature and check the condensate drain for coolant discharge and obstruction. Replace intercooler.
What to do if MTU 16V4000M73L Engine has pre-alarm?
If a pre-alarm occurs, it means the differential pressure exceeded 1.3 bar. Replace the coalescer filter element.
What to do if the MTU 16V4000M73L coolant escapes at intercooler?
If engine coolant is escaping at the intercooler, it indicates a leaky intercooler with major coolant discharge. Replace the intercooler.
What to do if the MTU 16V4000M73L speed is not stable?
Unstable engine speed can result from a defective injector, a faulty speed sensor, or a faulty Engine Control Unit. Replace the injector, check and replace the speed sensor as necessary, and replace the Engine Control Unit. Contact Service.
