I think if you fitted this particular car with the identity (VIN code) of another, it is to be expected that ABS and engine lose their codings. Me and golfi_vend tried only a CCM from another car in my car and of course ABS lost its coding.
i fitted CCM,engine ecu and ESCL from other car because cant adapt new ESCL,
I have autoscan before and old coding to,but not accept it,for exp. in ABS is still coding as before swap parts,but have error incorrectly coded and need some Basic Setting to perform
