Default Economy mode not activating?

I ran the car for a week or so, then it went dead, and just did a double warble on the key.
It turned out that the battery was down to 8V, so I put a new one in using the advised procedure. All now fine; and the alternator is working.
Obviously, I'd like to find out why the previous battery discharged itself.
When I turn on the ignition now, I get the "economy mode active" message if the car's gone to sleep. I never got this message AT ALL before changing the battery.
Here's the question: is it possible that the economy mode turned itself/was turned off previously (hence the lack of dash message), leading to the old battery discharging itself through systems not being shut down?
And the follow up: does the battery replacement procedure reprogramme the systems to set defaults, including activating the economy mode if previously disabled?
If the answer to both is 'yes', then I may not have to investigate the battery drain. Thanks for reading.

perhaps the old battery was not holding a charge due to age,,;;;is the car behaving itself with a new battery?

I don't know how old the previous battery is - it looks pretty new, but I have no way of reading the barcode on it.
I take your point though; I was going to swap it out anyway, as it seems to be a cheapish make.
The car's behaving now, so far; but I only swapped batteries yesterday, so it's much too soon to tell...

Is the replacement battery a brand new battery? If so have you had the alternator output checked to ensure it is not the fault? Have you checked the fan belt?

Economy mode CANNOT be turned off regardless of what some seem to thing it can be temporarily turned off but will reset once car is restarted.

Cannot explain why you never got it before must have been a glitch.

Replacement is a brand new Varta 027 size 63Ah thingy.

The battery taken out was not too old as the exact make and model are online today.

Belts are fine, and alternator output is around 14.6.

I read, on these forums I think, that the economy mode can be disabled by some programming procedure.

Good to know the the reboot (re-?)establishes economy mode.

Windy1603, I'm sorry I don't understand your banter, have no conception of what a parc shunt might be or where on a 'BSI' it's to be found. I'm still trying to locate the distributor rotor...

OK, found the PARC shunt fuse location in the manual, will check if it's in the right location tomorrow.

The PARC shunt fuse appears to be in the correct 'Customer' slots.
