Can't clear DTCs?

Postby asktoby » Sat Mar 07, 2020 5:16 pm

I've just replaced the glow plugs in my Megane.
I have a MaxiScan MS509 OBDII tool and would like to clear the diagnostic trouble code.
If the engine is running it will show the Glowplugs DTC that was there before I started work (P0670).
When I try to erase the code it says "Erase Failure. Turn Key On with Engine Off"
If I turn the engine off and the ignition on (i.e. press the Start button twice) it says the same.
Is there some trick to this?
