Been OCD about battery terminals, i thought lubing it will prevent corrosion in future.
Used this oil, but in about week i got nasty dash flashing lights with various esp esr abs and whatnot messages....
during ride randomly tacho/rpm dial went on-off.

now i degreased and sanded the terminals.
problems seems gone , motor starts better now... but esp error is still there.
i guess not many people here with citroen/peugeot experience; but i will try my luck with question:
can such error fix by itself with driving, or service visit is neccesary?
