I'm having some difficulty with BMW cluster EEPROM and Hexprog. I was working with an F02 cluster with 160DOWQ chip, which I desoldered and placed in the hexprog socket. When attempting to set or erase mileage, I would get a "Failed to unlock Chipset Reference: 2103" at some point in the erasing process. This would result in a random mileage being set in the chip. Trying to backup the original data resulted in the same error. I could not set mileage, erase mileage, or backup original data.
I decided to try the same operations with a spare 080DOWQ and experienced the same issues. It will erase up to a certain position, then fail. I was able to complete these operations using the exact same chips in a different programmer, so the EEPROM appears to be fine.

please send us the original eeprom and damaged one's.your eeprom is getting corrupted in mileage part that's why showing some random numbers.

160D0WQ_original.bin.txt (2kb) downloaded 4 time(s). 160D0WQ modified.bin.txt (2kb) downloaded 2 time(s). 160D0WQ revert.bin.txt (2kb) downloaded 1 time(s).

I think I got the 3 files attached. The original has a mileage of something like 147572km on it. The modified file is the result of trying to reset back to zero, and the third file is what happened when I tried to write the original file back to the chip. I tried with both the chip clip, and putting the chip in socket.

your eeprom file we tested with our 160dw IC and it is working.so i guess problem from your IC itself.

I did one 160DOWQ previously, and it worked perfectly on the first try. I used the clip and it worked in-circuit, didn't even need to take it off the kombi. After that first cluster, I've been having problems where I get the "Failed to unlock Chipset Reference: 2103" message. It always fails erasing the same memory block. With the 160DOWQ, it failed on block 14. Now I have been testing with a different 080DOWQ chip and it is failing on block 4. I have experienced this issue on 2 different chips, and both are functioning with a different programmer. Should I try clean install or something?
Here are files from an additional attempt with 080DOWQ. Hexprog managed to erase the first several blocks, but gave the 2103 message after working on byte 4 for some time. 080D0WQ_original.bin.txt (1kb) downloaded 4 time(s). 080D0WQ_modified.bin.txt (1kb) downloaded 2 time(s).
