Trying to source a new/used unit or a repair facility, any advice really appreciated. Tried Scuderia and no longer able to get new part. Attached are some pictures and I have already tried to replace a Capacitor with little benefit. Hoping that the forum will come up with a solution.

Many thanks Zep I'll give them a try. Getting new ECUs on cars like this is near enough impossible so heading down the repair route is the only way forwards. Their average rebuild price of Euro 340 also seems fair. There is also an outfit in Monza Italy that are offering this service https://www.f-autronica.eu/
Do you go German or Italian for repairs? I'm leaning towards the Germans ;>)

It’s the electronic equivalent of a grandfather clock. There are probably 8 year olds that could fix them these days. So you are probably safe either way ;)

My Brera ECU went to Germany,after three in the UK failed. Took 5 months but all good.

Found this info here under Problems/Ferrari; https://www.systemsc.com/problems.htm

Valeo Clutch ECU - The Mondial T ('93) Valeo clutch ECU (150393) can be problematic if the battery
is jumped, or if a battery charger is used with the ignition key "on" or to start the car. The typical failure
mode is the inability to disengage the clutch via the clutch actuator, not allowing the engine to start.
The ECU may also fail to engage the clutch. The ECU uses a potentiometer to provide the feedback
position of the clutch actuator in the clutch actuation process. Powering the clutch actuator directly
when troubleshooting should always be done with the ECU disconnected or the ECU will be damaged.
