What's wrong with it?
Martin, we had a KAD44 ECU fail earlier in the year and I finally managed to get the old / broken one home to have a look at it.
The old one was largely working, but wasn't giving any lights on the EDC panel nor was it allowing the boat to select gear.
I opened it up and couldn't see any obvious signs of failure. I have heard of one person who managed to re-solder a loose connection but I know no more than that.
The terminals looked OK on mine but weren't perfect. I do wonder if some very careful cleaning might bring it back to life.
I sent internal photos to one ECU repair specialist to see if they could do a component test however they said that due to the type of potting that has been used it is not possible to get to the PCB.
Nobody has any way of testing these ECU's (other than fitting one to an engine).
I'll be interested in other people stories / theories.
Thank you Petem ...
Unfortunately, you can't buy a new ECU, I wrote an email to almost every company I found on the Internet and to no avail, especially at this time ...

Martin, do they say that this part is now obsolete (discontinued forever) or are they waiting for a new batch to be manufactured?I can contact them only with local dealer.

I suggested Costal Rides in post #2Have you tried contacting Coastal Rides to see if they have a second hand one?
Also, have you posted a message on the Facebook Group "Volvo Penta Victims" to see if anyone there can help?
It's also worth joining boatdiesel.com and asking there.
You did indeed (I don't think your link is the correct unit BTW) but the OP didn't seem to have acknowledge your suggestion. Deffo worth asking them but I suspect these units are in high demand.I suggested Costal Rides in post #2
When parts are on back order , I have not looked into this but if it’s the case worldwide the dealer submits what is called an ARGOS case , must mean something different in Swedish ! The dealer submits this with the engine serial number , it is then Expressed to Volvo , this can only happen on an express order not a stock order .
