Working in a company producing electromechanical and software related products for the rail industry obsolescence is a big problem for us we have to support the train system for 40 years. Anyway currently new replacement electronic assemblies have to redesigned with new components which meet the latest standards using components which are lead free. Your better off trying to get the original unit repaired as this will be much cheaper than buying a redesigned product.
Found this company that deals with volvo boards. Hope this helps.

Ross , I am said engineer in this post , I am also local to this company , they were the first people I tried , and guess what the answer was a big fat no , they were not willing to touch something that is ,
A encased in silicone .
B. From a marine supplier with no knowledge of the components or the programme .
The marine industry is classed as a cottage industry , it’s on no where near the level for example as Volvo cars or truck and bus .
we are still waiting for an answer from Volvo on questions asked as to what the problem is supplying this part .
Until 4 years ago I was an owner of 2 TAMD 75 P engines , I glad to say I’m happy I am not , I would not want to be faced with this type of uncertainty.
I can however get parts for my 1975 Ford Escort mark 2 quite easily .

I have had a couple of fully potted motorbike ecus repaired over the years at bdk racing ignition and another company whose name escaped me, they both successfully depotted the pcb, and recently I was partially able to depot my seadoo mpem enough to repair it by putting it in the oven to 90 degrees and going at it with the dremel and a wire brush wheel until near the components, then a plastic bristled brush wheel.
It taken hours but it was worth it.
Failing that there are a few manufacturers who make custom ecus for truck racing that might be able to tailor something for you if there is enough interest. There is some discussion on rusefi on adapting their setup to do pwm control of electromechanical diesel pumps if you want to have a go at cutting your own cool.

Paul - Would you say to be fair that this is like the early days when ecu's and electronics when first introduced in cars - where by the pre ecu cars where just down to simple mechanics or basic ignition and now this situation with the Tamd and other early ecu driven boat the problems are only now coming to light.

Almost certainly.....possibly

That would be a good idea for someone but at the moment they seem to have gone very quiet on me so I will have to reunite their interest in my quest again!

I doubt I will wait that long to chase them up, after all, life is too darn short to wait a "Volvo" couple of weeks!

Do you know what actually caused the failure of the ecu?

To be honest , no we don't know for sure.
It may just have been old age, built in obsolescence or just tough luck.
It is totally blown internally and will not even pair with a test rig.

Not quite a normal mk2 Escort though Paul?

Good morning all.
I have just been advised that there is a meeting this week to decide if and when replacement parts will be made.
I will get an update again after this meeting takes place, watch this space.??

Hopefully all turns out good for you and other's that may require them in the future.
On another note it would be nice if Volvo wasn't interested in making parts from their "obsolete" engines that they shared information to able other's to remake and program them - but I cant see that happening as its all about the money

after all this pushing Volvo, I wonder if the price (if and when ECUs are available) magically goes up by a grand or so to 4k
good luck!
good luck!

Goes well in that case. You must have tuned it up a bit!

We had a failed ECU earlier in the year. Interestingly, it didn't completely fail, it ran the engines but wouldn't display the neutral light on the control pad and also caused gear engagement issues. I believe the ECU damage was caused by running the engine with a knackered battery (unknown to me at the time).
I've actually kept the ECU and will be testing it on another KAD44 engine. If it doesn't work on that engine then I might see if I can remove the potting as per @smdts post above.

Interesting. Didn't the wire brush get clogged up?
