This can oscillate quite a lot depending where you are measuring it and if the alternator is charging or not and overall RLC of the car system.
Adding a capacitor to ground can help but I would do it locally like you place the decoupling caps close to the supply pins of an IC.

in french now ?
plz donc forget that im french ... RLC ? .. IC ? ecu is ok
