Just to update - the PCU on our starboard engine also died... the error was "check actuator" - so swopped actuator from working side to dead side... same issue, so after swopping things around we found that the PCU was also dead, so 2 dead PCU's within a year on engines that have run 540 hours... really sad...
It took 2 minutes to swop it with the new one, then autocalibrate and calibrate driveangles, then all was good .-)
How much.

Interesting read this. I've recently lost the flybridge S/B engine control , D12s. Have been working with a local-ish VP dealer that have been only excellent so far, and its looking like it boils down to a failed HCU up on the flybridge helm. Am just about to order a replacement for them to load software on and fit.

But interesting comment from AndyRoonot there about leaving ignition on and turning off batteries, I'll try that when I'm on the boat tomorrow prepping for the cruise round to Dartmouth for a Monday morning lift out. am happy to give anything a go if there's a chance it'll bring the existing unit back to life..

I have just fitted a new HCU to a D12 , order it programmed you will need the engine serial number and state if it’s port or starboard , swapped the units over to pin point the fault .

If you want to prove this as an HCU fault then you have the luxury of a second helm station, and so you could simply swap the fly HCU for the lower helm & vice-versa. As long as you switch the stbd side unit at both helms then you won’t get any ID conflicts
Once configured (which is just a case of pressing buttons) if the fault moves downstairs then you’ve got it nailed. If it stays upstairs then you haven’t spent thousands on a new HCU…

Also, if it does look like a faulty HCU, whilst it would be significantly more than just replacing that alone, Volvo now offer an EVC Upgrade kit which would bring your existing EVC generation up to EVC-E4, and with it, access to much more modern displays inc. Glass Cockpit 👍

Great, Thanks Paul, no hint of any issue until 1 day it just came up as a light and msg on start up , and then obvs nothing on that throttle lever up on fly helm. I guess they do have a bit of a rough life up there !! Was it just plug and play once you get the unit with the software on it ?? Thx.

It’s worth stopping by the VP stand if you are going to the show as there is a display at the back of the stand for the upgrade kit, albeit in single engine form.

As attached, old kit on the left, equivalent upgrade kit on the right.

You don’t have to have Glass Cockpit, it’s just if you were looking for it then EVC-E is the minimum level you’d need to support it. There are other smaller display options, and yes, it’s more cost than just a single control unit but for what you get in the kit, the pricing really isn’t too bad if you compared it to buying the component parts of the kit separately.
