Welcome to the forum.

 

If it is the engine fuse box that needs replacing then you will not need to change the ecu or need any diagnostic programming. Make sure the replacement is from a car with the same options as yours so everything will work, presuming you are going the used part route.

 

What makes you think the fuse box is faulty, what year is the car and which petrol engine is it - 1.4 75 hp TU3JP or 95 hp vti ?

 

If it is the dash fuse box (bsi) then that is a different matter. Going the used route here would need the ignition remote keys, ecu, radio since they are all programmed together.

hi i had a guy come and do a diagnostic on it he said it was the fuse box under the glove box. its a 1.4 v8.petrol and its a 2002. just wondered if it has to be the same key as mine as i am not sure what the different keys mean. car went into eco mode tried to reset it but no luck. he said its the body control module if that helps. any advise help would be very much appropriated.

thank you.

The fuse box behind the glove box is the bsi (built in systems interface) one.

 

Is the engine running ? If not the eco mode will not clear until it runs and eco mode is not usually a sign of a problem.

 

Before going to the trouble of replacing the bsi, etc. I would use a Citroen dealer for a diagnostic check since I have read on here a few times where people have tried replacing the bsi/ecu/keys to match the ecu and bsi so the immobiliser works (or just the immobiliser chip in the key swapped but you need the keys from the donor car)/plus door locks and ignition lock (or just the key chip swapped)/radio or getting their existing one programmed in to the bsi - and at the end of the day the car has still not worked. So getting a correct diagnosis of the fault is important.

 

I have moved the topic in to a subforum since ones outside only show for a couple of days and are then hard to find.
