Just got this appear along with the orange spanner. Happened at about half throttle in third gear in sport mode. Any thoughts? Other than taking it back and asking for a refund... My venture into Megane ownership is proving very successful so far.
Came on when I started the car this morning. Stayed on for about 15 minutes then went away. I've read online that it might be a boost sensor or the wiring.
Need to get it on clip, could be a number of sensors, i had that along with something else when the air inlet temp sensor unplugged.
Well, the car is already booked into Renault for some warranty work, so I guess this will be added to the list!
In the mean time, check the plugs on sensors you can find in the engine bay, if its something thats coming or going, could be something loose.
