Came across this yesterday - one of two irremovable faults on a saloon with slight head gasket issues*.

Anyone had experience of similar faults? Diesels are something I know very little about!

Thanks, Adam.

* Had been experiencing water loss prior to anti-leak product addition; #1 injector is compensating with a fairly large decrease in fuel delivery at idle.

Postscript: First C5 I have Lexiated without aerial fault!

Probably just a glowplug gone down.

Thanks. It was the post-heating bit which threw me there.

Should I take the injector correction as a hint as to which one?
