thanks for that alan i have looked at it,my main problem is the autodiagnos doesnt seem able to show these pressures.have also watched an autoinform presentation on youtube by david massey from ads he was using autologic which showed the relavant readings and mentioned that sensors gave problems so need to ask around mates in trade for another scanner that will help.any further help with this would be appreciated a picture or good description of position of relavant sensors.
