No loss of performance or any discernible fault by the way

Yellow ECP warning light is on. My garage couldn't diagnose any fault but advised me to take it to a main dealer. No loss of power or any other discernible fault.

Anybody able to give an approximate estimate of cost at a main dealer of replacing an ECU.
