I think you should check your altered file (for OFF) if there was annulated all needed values for \SCR.
Sometimes something is forgotten and Ista is throwing errors. |

RE: X5 F15 25d SCR 805256 fault
My mistake guys, i disconnected the 3 connectors of the active tank
 Now i replugged the 3 connectors, unplugged SCR control unit and now it's better ! Only 1 message on NBT screen and 1 fault in ISTA If someone delete P faut code in DDE the problem should be fully resolved ? Thanks If this post helped you don't forget to press rep

RE: X5 F15 25d SCR 805256 fault
I did DDE update with e-sys, now i can correctly read ECU with K-TAG.
Can someone disable EGR, FAP, ADBLUE please ? Do i need to reset value or something before writing new modified flash ? Thank you |
