Engine shutdown but now fault MTU v10 Serie 2000

My first guess (strictly that) would be a fuel blockage, but it could be so many things.

A fuel issue would also result In other symptoms like low pressure, rough running, power loss. It sounds like an electrical or control problem. Loose wire or cable. If your engines can be started from the ER, try that and see if it shuts down.

Way too many possibilities and way too little info. Yep, could be electrical, brain or..... DK what other symptoms he had (like were his RPMs fluctuating), Given that it could be fuel flow and that's easy to check, but I suspect he has a visit from a mechanic in his near future if it's not fuel flow.

Yep, sounds like time to plug in the diagnostics.

If there are no alarms, nothing for the computer to diagnose (no codes). Being so intermittent, it would be impossible for the laptop to catch the shutdown code at the dock or within a reasonable amount of time. Fuel flow would show as an alarm. This is electrical, like the computer is seeing the key switch being turned off.

Try replacing the key switch and checking all harness plugs, then with the motor running start physically moving wires around and jiggling harnesses and see if you can duplicate the problem. Then have a marine electrician check all of the wiring on power supplies on the key switch circuit, harness connections, power supplies to the computers, batteries, battery connections. etc. etc. Sounds to me like a bad wire, bad connection, or key switch.

And do not overlook any ground wires to the ECUs, displays etc. years ago I had a fairly new car which would suddenly and randomly go into limp mode. Dealer could t figure out because there were no codes until an old fashioned mechanic checked the ground wire to the ECU... sure enough it was loose.

and I said earlier, next time start the engine from
The ER and see if it still happens.

Please return & let us know.

Hi did you ever find a solution. I have the same problem. I think its temperature related in the engine room. Once the temp goes above 42c the gauges reboot and then the engine stops and restarts. Had it happen at 2000rpm and 1000rpm. Check all wiring and cant find anything. No error codes apart from one time which was SE05 nd05 10+A001-sam can bus-1 error/bus defect

Hi
I have the same problem on my MTU engines.
It's the blue line electronics and also a friend of mine has tge same problem.
The ignition keys have been bypassed but problem remains.
Now he cleaned all connectors.
In my boat it occurred 2 times when I hit a wave so definitely a connection that is bad or a cable that has some corrosion.
If someone has some advice please let me know

I have the same issue with my Blue line display on my m91 v16 2000 series in my Viking. The port engine just shuts down while running perfectly like the ignition switch was turned off.
MTU Tech dosen't know what it is. It is getting worse happening more often Last trip it happened at 28k and the boat made an immediate left turn. Any ideas.

Before hoping to find a solution to such problem on a forum, after a technician specifically trained to work on your engines proved useless, I would consider changing it, first and foremost...

Capt. Ralph and Mapism,
Thank you, I will have my captain remove all the connections and check for corrosion, spray with cleaner and apply dielectric
grease on them. I had had a MTU Tech out 4 times so far with no solutions. I just replaced 4 turbos, charge coolers cleaned,
and a few other items that required a lot of disassembly. My situation ( engine shutting off) has got much worse happening on every
outing now. It makes sense with no power, no ECU code recording . I am sure cables were disconnected and reinstalled to complete these repairs.
I will keep you advised.

Don’t forget the fire suppressing system too. On ours, the signal is sent from the fire system relay box to the MTU control boxes at the helm. Could be worth disabling it for a test.

Where are you located?

Yup, that's certainly a possibility.
But upon activation, shouldn't it shut down both sides?
Tom only mentioned port engine...
