I don't have any specs on that engine . Only US ..
.. but if it has a fuel rail , [ EFI] it would be up front with a vac hose connected to it.. if so, pull the hose and see if there is any fuel evident. Should not be any.. if there is, it has a ruptures diaphragm and is allowing pressure over spec., which will cause the rich running and limit codes.
Is that a RHD car???
