yellow check engine message?????

cdtman · 5th October 2012, 22:32

Hi Rover 75 diesel men (and woman) anybody had on the message window saying in Yellow, CHECK ENGINE symbol light come on when your oil and water etc is OK , mine now comes now and then, I think for no reason,

Get it on some diagnostics, clear any recorded fault codes, run it until the light comes on again and run the diagnostics. It should then produce for you a fault code.

the light isnt for oil and water.the mil lights up to tell you the ecm isnt happy with the way something is working.as said by harry have the codes read then run car and see what code comes back ,you will then have an idea of why the light is coming up.

regarding my yellow check engine coming on when driving, yesterday after finding nothing wrong( tried all connections under bonnet),

decided to disconnect battery for a couple of minutes, the check engine symbol has now disappeared, been for a run and it has not come back on, so if it happens to you try that first . ?

probably a dodgy Lambda sensor?

If your car is a later model and the egr is isolated/ bypassed then the mil has been known to light up. It does on mine every so often but no fault codes are recorded on the scanner, so i press 'clear faults' and all is ok for another few weeks. hth
