« on: December 04, 2025, 03:03:20 AM »
Can anyone reset the flash counter on my MED17.5? Or does anyone have information on how to do this?

The counter is stored inside the Tricore chip on the eeprom part.
It is not properly a counter but blocks of data for each flash done.

Read attempts and success flashes on ECU via OBD mode, then read eeprom. Look for both of them back in order, there should be one or two instances of the counters. Change them to 01, correct eeprom checksum using WinOLS or another tool. Flash back and tada.
If you give me the advanced id output from VCDS and the E2P file I can change and correct them for you.

this is exactly what I did, but there are much more values inside! About 50 seats changed after loading by OBD.

Upload your eeprom file and I will try to help you.. I'm writing a simple C tool to help to find the km and correct the checksums.
