I recently replaced the battery on the wife’s C3 2012 Executive Picasso.
Since doing that the parking assist has not worked,(of course it’s my fault)

Is there a connection maybe? Anyone else come across the problem?
Car of course has been rendered totally undriveable, so any help at all would be great fully accepted. I have tried fuse F14. That was fine. I have also searched past pages and can’t find anything.
