Good that you've found what it is. Sounds like a warranty issue to me so would it be best for the dealer to resolve?
For interest I have tried to find which Ford cars use the 2.0 gdi engine - my findings so far indicate the most common is the Focus - but unfortunately the 2.0 gdi model is not available in Uk or most other European countries. Therefore, not sure whether spares for it would be available through the Ford network in these countries. The new Mazda MX5 has a 2.0 GDI variant - maybe this uses the same engine as I believe the Ford 2.0 gdi is originally derived from a Mazda 2.0 Gdi (from when Ford owned Mazda). Anyone know?
