I am waiting for your ideas and suggestions. Continuous economy

I am waiting for your ideas and suggestions. I always have the new 2008 2008 CITROEN c5 sxpk 1.6 HDI chassis vehicle. At 215 thousand km.

I bought the car at 160 thousand KM. Its steering was at normal power steering stiffness. But we changed the steering oil 1-2 months ago. The belt has changed. and we changed one of the round balls on that side.
For 2 weeks the steering was like cotton. it was very comfortable especially when parking. I didn't know it was that soft.
But now he is back to his old hardness.

They said it could be from the battery. I changed the battery. I put on 74 A Bosh. But the battery I installed was constantly entering economy mode. I said from the battery. We changed the battery.
Economy mode is constantly active in the new battery.

Could the charger be not filling the battery or not enough? Could the steering wheel be stiff due to this?
If I say there is a leak, if I say it is making chassis or something, so it is not going into economy mode. because I installed the battery and started the starter. I went 10 km. I was close. I got out, got on again, economy mode came into play.

I am waiting for the help of those who come to you or who have suggestions. mode active?

Economy mode is an active mode to protect the battery in these vehicles. So I think this is not about economy mode.

This type of vehicle has nothing to do with this mode, it is not electro servo steering, it is not hydraulic.
