can't open doors to get rpo code

hi all
I can't open the passenger door on my c3 to optain the rpo number I have looked in the maintance book but not been written in there I have tried the bsi reset but still nothing so car still in eco mode and no ingnition lights I have changed the battery for one that is more powerful to see if it was the battery at fault but still nothing is there anyway to get the code so I can use my lexia to see if it is a bsi fault
many thanks

RPO is just the date of manufacture. You can get quite close by guessing the date it was made by date of registration.

RPO info citroen-c3-tips/citroen-c3-orga-rpo-rp- ... -t204.html
There is a link in that topic to a tool to calculate the date, start at 9400 and work your way up to your guessed date

Its not a serial number or anything specific to the car other than the date it was born

ok many thanks will give that a try hopefully it will make lexia work my date of reg is feb 04 its on a 53 plate so d.0.b will be around march to December hopefully

Things didn't change much till around 2006 so you have a big window to play with. Each day increments the RPO by 1.

Non starter and dead, if not the battery could be a maxi fuse, one of the hidden ones under the engine bay fuse box. Often blow with a bad starter motor.

Will take the fuse box out tomorrow and have a look thanks for that info didn't know there was any more fuses under there all I get is eco mode and the battery light flashing but only if I turn on hazard lights
Many thanks

fuse box locations on the Citroen C3 topic.

Many thanks to c3cars for the information on the main fuse box great information found a popped fuse and now have ignition lights

Great work. Just bear in mind that high value fuses like those don't just blow to annoy you. They blow because of a serious over current situation on the part of the circuit that the fuses helps to protect.

If its the starter fuse, you may have a failing starter solenoid.

Any idea which fuse it was that had popped?

The maxi fuses are 'Citroen only' to replace, hence they are hidden from the usual fuses. The thinking is that 'if one of these has blown the car needs to be investigated further'...

It was a 30 amp the 5 th from the left you have 3 30 amp and then the 40amp then the 30 amp that popped thanks
