What this service does

A CAS3+ (Car Access System 3+) can be bricked when an ISTA-P flash, coding or update attempt fails or is interrupted — a common problem when programming these modules. The CAS goes dead: no communication, the car won’t start, and standard diagnostic tools can’t talk to it. We recover bricked CAS3+ modules on the bench, rebuild the corrupted firmware and data, and return your module working — with your vehicle’s data and existing keys intact. No need to source and program a virgin CAS.

Who this is for

– You or a workshop attempted an ISTA-P update / coding / flash on a CAS3+ and it bricked
– The car won’t start and there’s no communication to the CAS after a programming attempt
– The CAS3+ is dead on the bench and won’t respond to diagnostic tools

What we do

We read and rebuild the CAS3+ directly on the bench — recovering the corrupted firmware and EEPROM data and restoring the module to a working state, keeping your vehicle’s data and keys intact.
