Thank you for your answer.

In your opinion you think it can be a battery problem so? I think it's the original batter so i must change ok.

Ok for the battery charger too. However i don't understand "pull codes"?

Bad Batteries do cause a lot of warnings to go off in our cars so changing the battery is probably a good idea.

Our cars store error messages in their computers when something is not working correctly. "Pull Codes" means having a dealer or other car repair shop with the right software read those codes in the car's computer to tell you what the car thinks is wrong. Again, a bad battery can cause a lot of codes to be generated that aren't really what is going wrong but it is always good to check those codes.

Good luck!

Jim

I totally agree with you, i think i haven't choice, to solve my battery problem i must to maintain full time while sitting otherwise i'd still have problem.

Can you give me the name of your trickle charger please?

Thank you.

Mike Miller of BMW Car Club of America Roundel Magazine recommends this charger if you don't want to go the BMW factory route: (don't know about its availability in Europe though)

I recommend a Deltran Battery Tender Plus (www.batterytender.com) for storing these
cars longer than a week. The Battery Tender Plus is not a trickle charger, which will
overcharge the battery. It is a voltage-sensing battery maintainer, which sense when
voltage drops below 12-volts and then activates at a 1.25-amp charge until battery voltage
reaches 13.5-volts. Then it reverts to monitoring mode. Stay away from trickle chargers –
they are not for use when the car is stored unattended.
It is not necessary to access the remote-mounted battery to use the Battery Tender Plus.
The Battery Tender Plus connects to the positive (+) power tap under the hood, which is
located under a black plastic cover marked (+). The ground connector of the Battery
Tender Plus connects to any underhood ground including the grounding lug which is
located near the positive power tap. The unit also comes with a hardware cable, which
can be connected to the power tap and grounding lug and routed to the grill area or under
the bumper for ease of use.
