Boot only opens with keyfob now?
The boot always opened OK with the button on the boot or the button on the dash, as well as via the keyfob.
I had to disconnect the RCCM recently and then noticed that the boot only opened via the keyfob.
Reconnected the RCCM and the boot still only works via the keyfob, not by any buttons anymore.
What have I done?

Reckon I'm the one with the loose wire for buying this car in the first place.
I'm not alone with this odd behaviour, there was another member either here or on the UK site that noticed the same with his boot after disconnecting the RCCM, which is why I checked mine.
I also noticed that the MIL ilght came on once the RCCM was disconnected and the car was driven, which went out once the RCCM was connected back up again.
I've tried with wiring diagrams before and end up lost and confused?
On top of this, I've spent the day wiring in 2 x fuses to the DCCV wiring and jumpering a wire on the RCCM board only to find the blowers are still not working correctly. Hot on passenger side and cool on the drivers side, which is the opposite to how it started. Really p1ssed off now.

I've looked at the glovebox wiring and am wondering if this is a plausible theory. Assuming the basic wiring in all theses cars is the same for both markets and just that not all of it is used, depending on the market it's in.
In the US, there is a valet button in the glovebox. In the UK, it is not present. The valet button stops access to the boot via any buttons except the keyfob, which is why you'd give the valet parker the basic spare key, not the full function remote key, as per the owners manual.
On my car, the glovebox wiring comes out of the glovebox light as two wires on a brown connector. The wiring is then wrapped but at some point along it's 10" length, it becomes four wires which then then connects to a grey connector. This grey connector then goes off into the dash.
If I disconnect the grey, four wired connector, therefore isolating the glovebox, the boot will only open via the keyfob.
If I disconnect at the brown, two wired connector, the boot remains operational with all buttons as before.
I believe that the four wires are only used in the US, but not in the UK.
Does that make sense?

Aha - brilliant! I like the valet key theory. Looks to be that. When fitted it's just a switch so just shorts out a connection when NOT in use. That connection provides the enabling of the trunk button (and fuel flap etc). The UK spec is meant to be a permanent short i.e. permanent enabling of trunk switch etc. Disconnect it and it's like setting the valet feature.
