IDIOTIC BSI FUNCTION CONFIGURATION ??

[Ksi]

Hello everyone! Because I'm a stupid s**t mechanic engineer that sometimes has too much free-time, today I managed to totally mess up the BSI configuration and almost any other ECUs in the whole car...

The car is a Citroen C5 X7 - 2011 - 1.6THP.

I completely rebuilt the engine and the turbo because of the lack of power and also great oil consumption and it seems I managed to solve these problems.
Because I have a Launch tester, I thought it would be necessary for the new rebuilt engine to calibrate and configure different parameters of the car for a better engine functionality and response (like throttle body calibration).

Anyway, that's how I found BSI, ECM and any other cars ECU has "Configure" function, so I thought "Wow, soo cool, look how many things around here deactivated/not activated and so on...so I started messing with their factory configuration trying like an idiot activating functions car never had

Now, I got no more battery, "Parking brake faulty" error every 5 seconds, No headlights DLR and so on

Is there any possibility to factory reset the whole car ecus, or find ecus whole factory configurations by VIN??
Please help me, give me a hand, cause I'm in great trouble

A Citroen approved workshop can download the original ECU configurations, but I don't think that anyone else has access. The only alternative I know of is to find a car with the same set of options and copy the settings one at a time into your ECUs.

This is probably one where it is simplest to take the pain and get a dealer involved.

You could spend many hours trying to restore the original setup one code at a time, or an hour or two of a dealer's time to just load the orignal config from the Stellantis mothership.

Thank you very much for your replies!! Most certainly I'll go to the dealership to solve this situation...It seems even if I'm 26, I'm still a moron child full of curiosities...

Moral of the story learned: "Curiosity killed the cat!"

Thank you again to all of you for fastest replies!

Might I suggest (as if you needed it) that when you get the settings sorted out you record them for future 'safety', so that if you ever need to make changes you should have the information to hand to reverse those changes should problems arise.

Hi @Ksi, did you use a battery maintainer when using Lexia diagbox? If not, your battery might go below a treshold where things do go crazy, programming might fail, with corrupted memory. I also recommend you to go to a dealer or to a garage with "Stellantis approved" diagnostics.
