XZBMW  BMW F31 wrong checksum in KOMBI
Someone wanted to change the mileage in F31, he couldn't do that so now on Instruments I can see a BIG RED DOT. ISTA shows wrong checksum in KOMBI. Is there any chance to correct that checksum with ISTA or ESYS?

RE: BMW F31 wrong checksum in KOMBI
Looks like the km or VIN is stored in the processor too. I had to change F30 cluster because it will not let the car go to sleep. I found same part # as the original and swapped the eeproms. The new cluster is showing the correct mileage and works fine after coding, but the red dot is present.
