I guess it makes sense as the ECU will be weakening off the mixture for higher temperatures. The long term fuel trim is also very high at 25%, but I had only been idling the engine in the garage for some time so not sure if this is genuine .

Can anyone tell me please if these intake air temperature sensors are a common failure point on Renaults??

Also, Jules - does yours get worse as the engine gets hotter?

Before I change anything, I've just whacked a load of injector cleaner in it - see if that helps!

Thanks for any comments.

Mine gets better as the engine gets warmer !
