We can now supply a mod to fully disable CanCheck on BMW Philips (24c64 eeprom based) units.
This mod will allow you to re-use your unit in a non CanCheck vehicle or it can also be used to allow bench testing/repair of the unit.
A manual is here which shows the full procedure of this very simple modification and the units verified thus far.
It is likely that this mod will work on ALL 24c64 based units. User manual last updated 9th December 2007.
