Does anyone know how to read the cause of the EML coming on. It seems to only do it on warm days & if I stop the engine & immediately restart it, it resets & stays off, makes me think the trigger may just be a momentary fault but that the light latches on until the engine is powered off.
It was an infrequent event but now happens on most longish journeys. There is no apparent loss of power or anything else noticeable. If you google it - it can mean a number of things. Just wondering if anyone else has experienced same & thereby work out which on the list of possibles I should try first. [I am thinking dirty mass airflow sensor] Thanks
