Some error codes for comment please

Hi,

Warning light had come on but with no other symptoms (Note: Apart from the engine mounting bolt subsequently shearing and that is in the process of being fixed).

Codes:

17544 air leak, fuel pressure, etc
17705 hose leaking to turbo charger
17704 temp sensor, stat or water pump.

As above, nothing strange noted with performance.

Regarding 17704 I've noticed the temperature gauge is only getting up to about half way to 90 in this cold weather, but I tend to do motorway miles so that might be normal considering the natural cooling effect???

Thanks,

Tris.

Should be at 90 no matter what.
Are the vents hot when on HI?
If not Thermostat gets my vote, if not be the CTS.

Thermostat was replaced only a month ago. So that should still be under warranty. May just chase it up in case it has failed again!

Was it ok afterwards?
If not might have an air lock?

The other two codes point to a boost leak.
