Well, new pump cured it, but maybe I was barking up the wrong tree with the scope traces.
The PWM has changed very slightly but it is still nothing like the Megane trace.
In the original Kangoo idle trace, the PWM was at around 35%. Now with the trace below (new pump) it has come down to 30% which is the same as the Megane even though the Megane is going at a different frequency
Thanks for all your help guys
This is idle with the new pump
