What to do if MTU Engine shows pre-alarm?
- QqchaseSep 7, 2025
If the differential pressure exceeds 1.3 bar in your MTU Engine, it triggers a pre-alarm. To resolve this, replace the coalescer filter element.

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.
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 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 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 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 produces cloud of black exhaust gas?
If you observe a cloud of black exhaust gas lasting less than 5 minutes from your MTU Engine, it is likely due to a long period of low load. To resolve this, apply full load and wait.
What to do if MTU Engine room temperature is high?
If the engine room temperature is high in your MTU Engine, it could be due to leakage in the SCR system caused by high back pressures or high temperatures, or an incorrectly installed gasket. To resolve this, reinstall the SCR system, replace the housing as necessary, replace the gaskets, and check the gasket.
What to do if coolant leaks at charge-air cooler in MTU Engine?
If you notice coolant leaks at the charge-air cooler of your MTU Engine, it indicates that the intercooler is leaky, resulting in major coolant discharge. To fix this, replace the intercooler.
What causes charge-air temperature to be too high in MTU Engine?
If the charge-air temperature is too high in your MTU Engine, it could be due to excessive load, a high air intake temperature, an incorrect engine coolant mixture, or a contaminated charge-air cooler. To resolve this, reduce the load, check the fans and air supply/ventilation ducts for the engine room, check the engine coolant level, check the engine coolant with an MTU test kit, or replace the charge-air cooler.
