Re. the suspension switch:
I read in my owner's book that Fuse 34, 30A, supplies: 1/the Hydractive suspension and 2/the Central door locking.
Therefore I'd think the seller was honest to say that the purpose of the switch was to control the alarm, which is why u r getting the different locking behavior with this switch ON or OFF. Perhaps he didn't realise that it also hardenned the suspension. Or maybe he did, and then went looking for e-crofting kits, etc solutions....Maybe the switch had not been installed by himself, but by some mechanic in some garage who was instructed to "cancel the alarm" and didn't even know what the Hydractive is...
In the beginning, reading also about the e-crofting kit, I thought the switch had been installed by a person who tried to do fault-finding for his hard suspension. At a time I didn't even know if the cause of my hard suspension was electronic or hydraulic, I almost installed such a switch, but I'd have installed it on Fuse 19 which serves only the Hydractive ECU.
I did much testing on the motorway to feel the difference between soft-hard, and had become an expert in opening up the under-steering fuse box and removing Fuse 19 while driving...
I never installed that switch as I eventually solved the problem, but it'd be very very handy for similar purposes.

Hi George, thank you for that information
George and ekaftan, I acutally think you are spot on and thats what the switch was there for, the alarm rather than the suspenion, but the suspension has been cought up in the switch too.
As with the switch in the soft position, or as i would think the off position, evenything seems to be acting as it should, the alarm works, the indicator flashers work when unloking and locking, the orange sport light lights when the sport button is pressed. Also with the odd switch in the off or soft position when you open a door the click sounds and then is buzzes slightly as its in soft, then with the door close after 30 seconds it cuts out, leave the door opens and it remains on for a while longer. Flicking the odd switch ino sport with the door open stops the buzzing and goes straight into hard mode.
So it would seem that soft on the switch is the normal cars mode, the switch interferes when its flicked the other way and takes the power away from the ECU and disables the alarm. Though i will confirm this this weekend.
So it seems this is to disable the alarm, and not anything to do with the suspenion, it just so happens to take all of the power away from the suspension ECU. In which case ill leave the switch be, might be handy at some point, maybe if i want to drive like my hair is on fire (
clarckson technical term!)

On the plus side, it has the advantages of the Hydractive two with this little switch in one position and then with it in sports mode on the added switch its Hydractive one.
Is this a first, an Xm with H1 and H2 suspension
Ive got to say, i do use the sports mode on the Xms quite a bit, as i like how they feel and handle with it turned on, some nice twisty roads and flowing bends with the car in sports is a joy
