Does anyone know which ECU controls the Electronic Parking Brake?

Under the control of the ABS Unit:

Quote:

EPB (Electronic Park Brake)

A button activates and deactivate the parking brake, thus eliminating the conventional system for engaging the parking brake.
The button for the parking brake is located in the central tunnel.
The parking brake function is carried out by the ABS module.

Brilliant, thank you.

Sounds expensive

£1200 new from fiat so I am buying a used one from an identical car on eBay for £250.

Got the second hand one today. Taking to the garage with my fingers crossed tomorrow.
