I’ve just discovered that the 2017 model NC11 which I bought in August 2020 has engine problems which were anticipated by Volvo Penta in 2018 in a service bulletin which applied to several types of engine, including my D3 200 A-H engines. The bulletin recommended that the engines be removed and re-torqued. The cost was covered by Volvo Penta but the bulletin expired in April 2021. The engines (approx 300 hours) have been maintained by two Volvo Penta agents - neither of which has flagged up this problem. I discovered the existence of the bulletin only in May 2022. Both engines now require removal and repair. Has anyone else experienced this problem?

This is almost 30 hours of work involving the removal of the engines - inverting them - re torquing - reinstalling! I suggest you get your Volvo Penta engineer to check your serial numbers against the bulletin and seek answers from Volvo Penta UK
Be careful to power up fully for a while regularly to keep your turbos clear of carbon deposits. The removal of the engines will be a nightmare as there is inadequate space in the engine bay. The designers did not anticipate this being necessary.
Is there a way to look up, perhaps via HID or engine serial numbers, to see if a boat needed and/or received the fix from a technical service bulletin? We're looking at a 2015 NC11 and want to know if this was required and/or completed. Thank you!
Yes. Get your local Volvo Penta appointed engineer to check the serial numbers of the engines against the VP data base but be aware that the service bulletin issued in 2018 was withdrawn in 2021 and may not recognise the issue without further investigation.
