Problem P 406 HDI!?!?!

Help me! I have P406 2.0l , 80 kW, 2000y.
Today my car went crazy!
I did not open my remote key.
The engine is running OK, but the electronics in the cabin canceled
obedience, the display first appeared in the notice of error ABS (not
true), then information about the low level of brake fluid (not true).
When I parked the car and I was switch off the engine, at departure
appears sound that a some device is still on but is not!
After 30 minutes I return to the car and see that the lights in the
meantime switch on??
The only thing I could do to after parking is disconnect the battery.
What it could be, and what should I do?
Perhaps to reset the BSI or what?
Thank you very much everyone!

 

I forgot, last two days whether were very wet (rainy)!

 

PROCEDURE FOR BATTERY DIS-CONNECTION (The 3 Minute Rule)
Whenever a vehicle battery has to be dis-connected, switch off all
equipment, interior lights etc, close the doors leaving the drivers
window open.
Switch off the ignition and remove the key and any DIAG equipment.
Wait a full 3 minutes before disconnecting the battery.
The BSi must be allowed to go to SLEEP ie into "power save mode". Do not
operate any equipment on the vehicle during this time. Remember, even
opening the bonnet will wake the BSi on a vehicle fitted with alarm.
If the battery is under the bonnet, open the bonnet first and leave it
up. 807 batteries can be dis-connected through the drivers window,
remove floor cover first.
ALWAYS disconnect any DIAG equipment and do not operate any plips from
other vehicles during the 3 minute waiting period.
PROCEDURE FOR BATTERY RECONNECTION
Unless otherwise instructed by Peugeot or Product Service, you must
always carry out the following procedure, often referred to as a "soft
re-boot", to minimise the possibility of the BSi corrupting its own
software when reconnecting the vehicles battery supply.
Ensure the procedure for battery disconnection has been adhered to and
importantly all BSi functions were switched off with the drivers window
left down.
1 Close all doors
2 Remove ignition key if left in ignition
3 Reconnect battery. DO NOT open any doors
4 Wait 10 seconds
5 Switch on healights through the drivers window (you will hear a "bong")
6 Switch on ignition then start the vehicle and check system functions

NOTE: Upon reconnection, if any vehicle function controlled by the BSi
i.e . interior light is switched on,the internal operation of the BSi
has the potential to spike or corrupt its configuration and software
program......
