I have a 2013 C4 Picasso II. It has started displaying error "Engine Fault Repair Needed' when I slow down to stop. Sometimes see ECO mode deactivated message. Cruise control is not working and I am also seeing parking sensor errors!

I have taken car to citroen dealer who said that this is alternator fault and will need to be replaced. However when getting quotes for the repair one garge suggested getting the battery tested which showed that it needed replacing!

Can anyone suggest how I should proceed? Replace the alternator or the battery?

If your car still has the original battery the chances are it needs replacing at seven years old, modern cars are reliant on a good battery and if it is less than perfect all sorts of spurious error messages, one that I had in the past did this showed several random error messages. All was well after new battery

I would get the battery and altenator properly tested and take it from there.
