"Check Engine" lit on a Disco...

GRRRRRR

filled up with fuel, and as I pulled off the forecourt, the Disco didn't
feel right. Got 150yds, and the revs were going from 500 to 2000 and back
again at about .5Hz.

Couldn't pull over there, so got another few hundred yards, and the "Check
Engine" light came on.

Stopped, restarted, and all appears ok, but that damned light is still on

Is it a "dealer" job to get it disabled? or can the homebrew mechanic jury
rig it?

Si
(still not properly back to work after 8 weeks and getting really fed up
with being told "you cant do that" by SWMBO)

Seeing as it did it just after you'd fuelled up, try removing the fuel cap,
check the seal is ok and refit it ensuring it goes all the way down and also
ensure the cover flap closes fully also. Tank vacuum leak-rate is monitored
by the ecu for emissions reasons and will give the light if all is not ok.
Common as muck situation on BMW's, btw, and guess where the motronic ecu
came from......

Not 100% certain, but if it doesn't, try unplugging the ecu (with the
ignition off, obviously!) and waiting a few minutes then reconnect and see.
Don't just disconnect the battery as that may cause alarm/immobiliser
issues.

My plan B is to swap the ECU from the Charities 3.9 to see if that clears it

might do that anyways ;-)

Plan A disconnect ECU count to 50 and reconnect worked a treat.
