Hi, I have a problem with cas4 (5M48H) in F07.
I need to replace it, I have a donor from cas4 (1L15Y) with working key.
How to make it work?
Is it enough to swap them and coding or need to do ISN in cas4?
I have tool for 1L15Y, but don't have tool for 5M48H, so can't read it.

Hi..you can try to do it but I think your donor cas not compatible..It is 1L15Y used on older models..I am prity sure you will need 5M48H or 1N35H maskets at least I did when I crashed cas4 before..for adaptation part best way is to read old cas4 eeprom(if avalible) and write to donor(at least xprog needed)..or like you say new cas4 + key so you can read/decript ISN and transfer it to ECU..all can be done by autohex.when you finish ISN part make coding and programing with..I didnt have time to play with 1L15Y maket becouse customer was breathing on my neck :-) but if you alredy have it is worth to try

Autohex can not decrypt using key

same mask is needed and full clone.
