Focus RS TroubleShooting
My 2017 RS has a developed an engine noise during a Rally-Sprint. (Tarmac)
It is 20,000 klm young (12,500 Miles) and has seen about 80klm (50 Miles) competitive driving.
Not the 'do you think that's actually a thing' straining to hear it type of engine noise, but a bonnet (hood) down, sitting...
