2.0 TS CF3 no start
2003 GTV 2.0 TS - CF3/drive by wire engine
so... engine light had been on and off for a month or two. MultiECUscan indicated a problem with throttle potentiometer. So after a search on here I went up under the dash on driver's side, found the white connector that apparently causes trouble, played with it a bit, engine light went off and stayed off, no fault codes showing.
Couple of days later, i.e. this morning, it didn't start. No coughing or spluttering or signs of life when cranked. after a few tries it started and ran perfectly, but did the same when I left to come home this afternoon. MES says U1600 - Electronic Key; suggesting it's a code immobiliser problem.
So I guess I disturbed something when poking around trying to sort the throttle pot. problem, but what might I have done exactly? Can anyone tell me where the code box is and whether there's a receiver coil around the ignition barrel in the normal way, where the connections between these components run etc etc?
Thanks in advance!
