A Class A168 immo problem

[Tyson500]

Hi can someone pls help to repair corrupt dump for 1D69J

For a mercedes A160 168model

Immo Unit 1688200426-5wk4736

Think something went wrong when I read it.

Info of steps.
1.Car came in for duplicate key, so have original remote key working.
2.Read with ak400 (think this where it went south)
3.Saved file successfully
4.Put file to tango, recognized it.
5.Generated new TP with Tango
6.Put IC back on immo unit - so i did not write any data back.
7.Car dont start with either key.
8.Got secondhand immo transferred data still no comms with immo.
9.Put second hand immo with transferd data into donour car also no comms. The second hand immo had comms with donour vehicle before i transferred ori data.
10. Fault codes in ecu P0600 and P1570

I also suspect a fault on the car as well (maybe ecu) cause i am not getting comms with a good immo unit in it.

Any help will be appreciated.

Are you sure that you are soldering back mcu as well as needed ? If file where wrong i think tango won't recognize it

Hi try connect emulator ,no more trouble with immo.

Hi simplo, yes confirmed solder 100%, soldered to second immo unit to confirm.

t77 is there a emulator for MSM 2.0 A1661413125(on throttle body)? do you have a link for it. My emulator can only work on 1.7cdi and MSM0255454123.

Look here ,last is for VDO MSM petrol

Eureka!! I managed to fix the problem. Turns out just because a processor can read and write in the programmer it does not mean it is 100%. I Wrote info onto another processor used the same hardware and BOOM.

Thanks for advice. T77 i also use that emulator but don't work on the A class with MSM 2.0

Common problem that processor goes faulty on these m8. Glad you solved it ..
