I sent the car to the main dealer for a service. The car came back with the engine warning light on so I sent it back.
They checked and found not issues, reset and said they would deliver back.
The day before delivery I get a call that they were putting the car on the trailer and it wasn't working properly and stopped and they could hear a loud ticking noise from the engine bay.
Turns out the ignition ECU mulfunctioned ( i wonder if it may have anything to do with having disconnected the battery and then not gone through the full re-learning procedure on re-start up)
ECU was sent back to Ferrari but they said they dont have the capacilty to look at it for a while and I cannot find another ECU on the market (part 210116)
Quite frustrating. We have the option to send back to Bosch.
Any advice from anyone having experienced the same or who can source this part?

The ticking noise is the throttle body - the MOSFET that drives it is will be toast. Unfortunately I've not been able to repair one as yet due to the ECU construction.

In the past your only option would have been to buy a new ECU but it is possible to utilise any used 360 engine ECU, regardless of part number. You need to find someone who can erase the immobiliser pairing in the EPROM and transfer the firmware from your good ECU to the replacement. The people mentioned in the post above are the only people in the UK who can do both of these things.

Thanks Aldous much appreciated.
In fact I have managed to source a new part but your post got me thinking ... could it be the MOSFET failing by itsef and nothing to do with the ECU? Apparently the car would not restart after filling it with fuel and that loud ticking noise started when the ignition key was in.

The MOSFET is part of the ECU. It's job is to convert the signal from the Chip (which is in millivolts/milliamps) into a powerful enough signal to drive the motor in the throttle body. Inside the ECU the components are covered in a transparent glue which makes repair impossible. Picture below...
