    Morning All, Just come to me that when i cleaned the intercooler pipes a couple of days ago and reconnected, I forgot to plug the map sensor back in and just thought it was limp mode again. But the strange thing is i had no eml warning just wondering how could this be when every other car iv'd had comes on as soon as the engine is started?? 1.9 awx engine. Thanks In Advance for any suggestions.

    This does happen sometimes ive found, Fault codes can be present but no engine light. The map sensor will be reading boost pressure, so id imagine if would be pretty flat to drive
