Thanks Lee
Since then, the code has come back again but no EML yet. That is how it used to be code would nearly always be there and then EML would eventually come on after a few days.
I found the other tests in Basic settings (not output tests)
The EGR would cycle on and off and I could see the EGR actual was always more than specified, and even so the EGR always seemed high as in even at it would only go down to about 280mg/St. and up to 420mg/St.
I will check the vacuum system with a vacuum tool and also block off and check the EGR valve operation and air-tightness and check valves etc....
Thanks again. Car is driving fine though and never any smoke.
