The air outlet circulation pipe on the newer 1.6TDCi has been re-designed to help relieve pressure from the turbo better,
If unsure about any ford; get the reg and type it in to ford etis for full information on build date to engine model and chassie number all for FREE!!
The 1.6TDCi engine is helped if serviced in compliance with manufacturers spec.
As a precaution you could get the turbo oil feed pipe replaced as it is this part that blocks with oil causing oil starvation in the turbo as result overheats and PoP!
Cheers for that Lenny do I have to register to be able to use reg number as it's only giving me the option of using VIN number?
As for the turbo oil feed pipe is it a relatively minor job? The CMAX i've seen appears to have full Ford history but from what i've read this doesn't always make a difference due to length between service schedules?
