i have a citroen c2 with flappy paddle gearbox thingy.
the battery went flat and after changing it the car will not go into neutral
it's been plugged into a modus and the modus says it's in neutral
any help please
many thanks in advance

Try disconnecting the battery then unplugging the ECU and leave it for about 30mins.

Sometimes helps rest everything.

tried that still nothing but the battery light flashes!
