hello guys i want to ask you for help with FRM2 repair. the problem is that the unit does not communicate, but it is possible to read the UIF with INPA. I guess it's a bad eeprom, so I managed to read it with xprog. I fixed a lot of FRM3 but I don't have much experience with FRM2. So thank you in advance for any help.

It is FRM2 E70 XE 
6135 9153803
HW:0x07
SW:5.30.51

have you tried programming with winkfp?

however the fastest solution in my opinion is to take a frm3 and encode it on the car.

I tried, but it would not communicate. Friend brought it to me for repair, if it is possible. In the car is already new one.

So i wrote eeprom from different FRM2 a now it works.

Nothing didn't worked for me. FRM2 are dead ... no comunication from them

if you also did write the flash your frm is indeed dead as it does mis data...
your solution is, write  eeprom from ori frm to "exact" same donor and leave flash alone

there is a solution for this error on reading mcu but you need knowledge for this

This eeprom worked in my case. Try it and let us know.
