For what its worth - the code reading via the dash is of very little use at the best of times. The codes shown on there are rarely direct fault codes from the engine ECU. Most of them are from the GEM module/dash setup.Dicko - if you want to send some screenshots of the live data from the Autronic over to me i'll happily take a look at them and see if I can see anything out of the ordinary.It is possible that a sensor is playing up as has been mentioned. I'd quickly check the pipe connection to the MAP sensor too for what its worth!
