Good news for anyone with a blown engine. Ford have today said that they will refund anybody who has had a blown up engine in full. That includes any retrospective claims and seems to relate to the degas hose issues and cylinder heads.
The turbo coolant pipes and de gas pipe are rusty on my 2013, if they perforate the coolant loss will cook the engine in a very short time. My neighbours Fiesta is the same year but has what appear to be stainless pipes.
Japanese cars are looking very likely for my replacement in a few months time.
