I am off on holiday soon, and maybe leaving the D3 parked up for three weeks at home.

Now my D3 has a small current drain, which means that if left for a week the battery is pretty low. Now I'll be leaving it for 3 weeks, so it will most likely go flat if left connected.

Does anyone know how (if its possible) to lock the car after disconnecting the battery.

I'll let you know I tried this 18 months ago and failed, and in the end left the key with a neighbour to start and tun the car for 1/2 hour or so every 5 days.

What I have tried that failed.

A)
Use MMI to disable the central locking on all doors and boot, except the drivers door.
Lock and unlock the car, then lock it again with the boot open.
Disconnect battery.
Great except now the alarm goes off.

B)
As A above, but this time leaving the car unlocked.
After disconnecting the battery, there is no way to lock the drivers door. The key can be used in the mechanical lock, to open a locked drivers door but not lock it.

Using A, all is fine except the alarm goes off.
Using B, all is fine except the drivers door remains unlocked and cannot be locked.

Anything in VCDS perhaps.

The car is kept outside, so hooking up a charger or similar is not really an option.
