Not sure about YWC500312 I think it is for very early cars, but YWC500730 is a superseded part number for the other three units.

Early modules enable the fronts and slow speed

Surely they all work at low speed wouldn't be much use if some only worked at 50mph. |

I think you missed the word enabled |

There was a switch on the dash of my old 09 plate which switched the fronts on and off and the PDC automatically disabled at speeds over 10mph so not unique to early versions.

But how do the front get enabled ? If you just drive forward into a space.

OP, what’s the symptom before you replace your module? These cars have problems with the wiring to the sensors, it’s very unusual for a module to fail. 2019 5.0 SC SVA (Current)

You have to switch them on first using the PDC switch, unless you engage Reverse first then into Drive, it's the same on the facelift variant if memory serves me correctly, but could be wrong on that as can't remember last time I used the switch. Not sure what the range is but guess the fronts would keep going off in say slow moving traffic if permanently enabled Cheers Col |

That’s what I thought.

That would drive me crazy in a traffic jam. I can see why it was ditched! 2019 5.0 SC SVA (Current)

The only issue is when cyclists go past
