Volvo Penta D4 WOT Error

[pete78]

Hi all,

I’ve got a Jeanneau prestige 34 with VP D4260’s, 650hrs.

On 3 or 4 recent occasions I’ve had a ‘check engine’ error message on the starboard engine if I go WOT when accelerating , or going for a high speed run. The first time it was accompanied by a limp mode/ limited revs and yesterday when it occurred full power was still there.

Once I’ve restarted all error messages have gone. I was advised to change the primary fuel filter as it may be a fuel flow issue (now done), the fuel is crystal clear, and all other levels are good. Boost pressure is also matched across the engines.

I have a service in a couple of weeks, so I’ll get the engineers to check it out then. I just wondered if anybody had any ideas or suggestions as to what it might be?

Thanks

Is the service engineer from a VP dealer? If so, get them to plug Vodia in. The faults will still be there even if they are no longer active. My money is on either a fuel pressure or temperature fault if it only happens at WOT

Thanks - they have vodia, and I’ll get them to plug it in. Do you think is likely a sensor, or another mechanical problem? I’ve tried a bit of searching, but couldn’t find any reports of similar fault, so wondered if other may have had seen this before.

Cheers
