Ds3 crossback Speedo gone blank + crash data in BSI

[theRage]

BG: DS3 salvage repair I am undertaking.

Changed seatbelts and airbag ECU, but there is crash data still showing in BSI which I believe someone with Diagbox can clear for me (or I need to remove and send BSI module to be cleared)

Also, digital dash speedo screen was broken so I bought a replacement screen. Fitted but it's just blank. I returned the old screen but it's also blank.

My Autel BSI error codes are attached for the 2 issues.

I live in Derby and would appreciate help with these 2 issues.

Thanks

I can not help much but you need to be aware when swapping speedos the car will adopt the highest mileage of the old one or the replacement one if it is on a higher mileage. Same applies to the bsi.

Thanks, I don't know (or think) the speedo circuits were fried that I'd need a new board. Does a thing like a relay or fuse exist, or something cutting off it's power supply. The HUD works and I still get the beeps that come up during engine checks (obviously from the speaker).
