Some users reported that foxflash failed to read Mercedes/Chrysler Siemens EGS52 or EGS53 TCU. They can see it in the menu, but unable to read?
Foxflash will read/write EGS52/EGS53 in boot mode if ECU is not encrypted.
If you fail to read EGS52/EGS53 in boot mode, make sure you don’t connect the bench box during boot operation.
