Hmm thanks Coupster. Was hoping others would not show cracking. Not to say of course that mine may just be a few months ahead of yours. Could still be the issue. Plenty on the net to assist with tracing the fault but you need to know where the various components are located. That's one of my problems. The pump is obvious as is the exhaust valve but can't find where the solenoid is.......

Looks like I may be onto something

Yes it's the EGR valve. Fingers crossed......
Result on EGR?

Not sure Coupster. Code waited longer to return but return it did! Wondering if it could be an intermittent relay next. As far as I can see on this engine the system consists of a feed a fuse a relay a pump a valve and finally a "whatever" which signals the failed state to the ECU. Since the purpose of this system is to warm up the cat quicker I'm guessing there is a sensor after the cat which signals the ECU. Can't find anyone to clarify though.
