Gentlemen,
A question. I am in a sort of quandary. Intermittently when I jump into the beast and insert the key I am faced with the hazard lights coming on and the interior lights lighting up.
I have to manually switch off the hazards and the interior lights.
The beast starts, no problem, but I have noticed that the master lock switch (below the hazard lights) does not lock the doors.
If I switch off and then restart all is ok.
As I say it is intermittent, I thought that I was pushing one of the buttons on the key but no.
Any thoughts?.
Beast is a FFRR Vogue, TD6 MY06.
Thanks in advance.

PS getting the FBH upgraded seems to be impossible in both teh UK and Belgium!

It seems to be related to the tailgate. Try to close the tailgate again, at least it's like this that I get rid of the hazards and lamps thing.

Having now had sometime to read it would appear that this is indicating a Crash Signal. - ANy thoughts on how a crash signal is activated when the beast is stationary?.

Crash Signal
When the DCU outputs any of the fire signals it also outputs a crash signal to the Body Control Unit (BCU) and the
ECM. On receipt of the crash signal, the BCU goes into a crash mode and the ECM cuts the power supply to the fuel
pump relay. In the crash mode, the BCU:
l Activates all of the unlock signals of the vehicle locking system, even if the vehicle is already unlocked
l Ignores all locking/superlocking inputs until it receives an unlock input, when it returns the locking system to
normal operation
l Activates the interior lamps. The interior lamps remain on permanently until they are manually switched off at the
lamp unit, or the BCU crash mode is switched off and they return to normal operation
l Disables the rear window child lock input until the crash mode is switched off
l Sends a crash message to the Light Check Module (LCM), via the K bus, instrument pack and I bus, to activate
the hazard warning lamps. The hazard warning lamps remain on until cancelled by the hazard warning switch or
the crash mode is switched off.
The BCU crash mode is switched off by a valid locking and unlocking cycle of the locking system.

No idea if it has anything to do with interference, but I have noticed sometimes in Valet parking lots if there are several other RR near mine when I request my car upon return, if they have to move them around to free up mine, sometimes my alarm starts going off for no apparent reason (paved lot on solid ground so not an issue of moving heavy vehicles on a suspended floor of a parking garage leading to vibration/shaking). Not really the same issue you are having but it has had me scratching my head a few times and may have something to do with interference. Only seems to happen when other RR are nearby. I've never had it happen anywhere else.
