I changed the oil in my Ford Fiesta - why won't the turbo work now?
I changed the oil and filter on my 2012 Ford Fiesta. Now the engine fault light is on and the turbo isn't working.
I would guess that some carbon has shifted and is blocking the turbo bearing oil feed pipe and also preventing proper circulation of the oil. Probably need to replace the turbo oil feed and oil return pipes.
