    Default burnt piece on cas3

    hi alli tried to do milleage change on 2008 bmw e60 cas3

    these are before and after files
    can anyone tell me if these files seem ok

    the pic is a surface mount resistor or something which looks like its popped or burnt

    can anyone look at the 2 files and then look at the pic and explain what i might have done
    to stuff up the cas3 because nothing is turning on in the car

    would anyone know what part it is so i can try replace it because a new cas3 from bmw is 700 dollars

    thanks

    Cas3 throw it in the garbage, buy another used and do the job professionally

    hi soxtan
    I originally used an r270 and was fiddly to read and write
    so not sure if that's what popped it
    so I'm wondering if there is a safer tool to read and flash the used cas3
    thanks

    Sideshow, if you are still wondering. It is a 3.3ohm resistor. Arthur.

    ah thanks for that I might try solder in a normal resistor and see if that makes the cas2 wake up

    I still want to know if the r270 could have done this
    or my bad soldering

    I modify engine looms daily so have been soldering for 20 years
    and do mileage change on some clusters
    but this was my first time using r270 so need to know if it was my fault or the chinese tool
    and if so buy a better tool

    thanks

    well we decided to give a new resistor a try soon
    prob wont work but worth a try

    so if I have a good read of the orig cas3 dump
    can I flash that into a used cas3 from another car and will it work

    still don't know why the resistor would have blown in first place just from writing a file to chip

    unless it didn't write properly and it turned something on at wrong time

    ill get dumps and post them up here to see if anyone can see if they are faulty or corrupted

    thanks all for the replies
