Engine management light on

[Tim watson]

Hi guys
I have a 1.2 puretech citroen c3 2018
The engine management light came on saying catalytic convert bank high.
The cat has been changed and the readings are now saying fuel temp 4000 degrees below zero.
And still the light came back on.
New map sensor fitted and still the light came back on.
An auto electrician looked at it and said it could be the bsi body control module.
The reset routine has been done to no avail.
I'm at the point of hitting my head on a brick wall.
Any help will be much appreciated

Don't do anything until you have had a proper diagnostic run. Provide us with any and all fault codes (preferably using Lexia or Diagbox) along with the VIN. Absolutely no point in replacing expensive parts before doing this.
