Spanner Juggler,
As far as you know,is the info. re relays pertinent to the latest cars or have things changed?
The location has certainly changed as there is an electrical centre under the bonnets above the drivers knees on RHD cars. As to the specifics of the relays I am afraid I have no idea sorry? Not worked on the latest cars as they have not worn out their kingpins yet ;-).
Whoever dreamed up the idea of putting relays and fuses in inaccessible places needs to be condemned to a hell where a fuse or a relay blows out every 10 minutes or so on a dark and rainy night.

I'm glad to hear that they have "seen the light" on the latest models.
PS. My 2012 car did not come with any indication of which fuse was for what so I made a diagram from information on the wiring diagram. The relays do not include the aircon relays.
