I have now noticed the boiler works perfectly when the time kicks in in the morning that is until I use the hot water then the cycling begins. Could this be a fault with the diverter valve? Thanks in advance.

Pinking is a sharp mettalic ping under acceleration is this what you mean? Or are you talking about missfireing and loss of performance. The Zetec Ford has a problem with plug flash over on number 3 4 cyls due to the positive polarity of these two cylinders. Fit new plugs and don't gap them over...

Yes, it affects CH and DHW.

Yes, it's the same on HW and CH, however I have noticed the fault disappears when lit from cold, once it has warmed up the cycling begins.

Boiler is Sime Friendly Format (Combi) Problem is boiler lights then goes out then lights and so on, radiators get nice and warm; water is not as hot as it used to be. Changed thermocoulple, thermistor, limit sensor, overheat sensor, and frost stat, checked air switch, anyone got any ideas.
