I am looking at a 2015 RR Sport SDV6 and understand that the belt change is due and hasn't been done. I am trying to understand whether the timing belt and hpfp is supposed to be changed in situ on these vehicles and is simpler (sort of) than on my current D4 where body off is recommended?

I have searched high and low but can only find descriptions and movies about this for older vehicles (Discos and RR1s).

Change them in situ

That said, D4 isn't body off either...

Thanks, Mikey. Much appreciated.

I am aware that some with appropriate skill level do it in situ for D4s. But for mere mortals body off may sometimes be the way. And when it happened the cross-over pipe was leaking and also the brake lines pre-emptively replaced.

Good to know about the L494 though, as I now better know the negotiation space for the belt change that lies around the corner for the vehicle that I am currently looking at.
