About CAS3 files

CAS3 is a BMW Car Access System immobiliser module. We currently have 41 CAS3 files in stock and 32 hardware numbers. Each one is an original read from a working unit. Vehicles that use this unit here include BMW and MINI. Frequent models: 520D E60, X5 E70, 320D E90 and X6 E71. Available as EWS / CAS dumps. These dumps were read with XPROG, VVDI PROG and MULTI PROG, so they load straight into the same tool. Always compare the software number on your label with the number in the file title: two units with the same ECU type can still need different software. Missing your version? Request the file with the label numbers and we will source it.
