Hi all so today I took off the plug/sensor to have a look at my air filter. I stupidly then put it back together and drove to work 5 miles the car lost power and then I realised I hadn't plugged the sensor back in doh! Now I'm getting a message saying 

Emissions workshops? And the engine management light stays on. HavIn plugged it back in the car runs fine how do I get rid of the message or can I thanks all

@sumpplug - You can wait and it might clear itself, or you can disconnect the battery over-night (if you have the radio code anyway), or you might be able to shift it permanently with a code reader.
