Flex 8.18.0.0 Supports Mercedes CPC5 Boot Unlocking

Magic Motorsport Flex adds new boot glitch unlocking protocols on September 8th, 2026.

Version 8.18.0.0 of Flex Out Now

Mercedes Truck CPC5 control units installed on vehicles produced after 2020 are now among the new units supported by Flex + Korhex.

The dedicated procedure allows you to work in Boot Glitch mode using EMFI — Electromagnetic Fault Injection technology, with support for the latest Mercedes Truck heavy-duty vehicles, including Actros and Arocs.

Position Korhex, follow the Flex-guided procedure, and directly access the SPC58 microprocessor.

In order to use the protocol, you need either the FLS0.20 license or the Flex Full FLS0.5 configuration.

Flex Software Freezes? Try These Solutions

Problem: The screen suddenly goes a bit darker and the Flex programmer software app freezes. At the same time, the USB and update icons start flashing red. It only started doing this in the last couple of days. Any ideas what could be causing it?

Solution:

1). The laptop is on standby. Quick reboot and its fine.

2). You are running it in browser. Use the software application.

3). Flex suggests uninstalling everything and doing a clean install.

KESS3 Update OBD Protocol for BMW Mini MD1CS001 "Locked" ECUs

Alientech KESS3 released a new OBD protocol for Bosch MD1CS001 locked ECUs with KESS3 and Powergate.

The Bosch MD1CS001 ECUs fitted to recent BMW and Mini diesel applications with 1.5L and 2.0L B37 and B47 engines can now be read and written directly via OBD after the initial BENCH unlock with the dedicated KESS3 protocol. This is the first of several releases for these ECUs.

• Unlock the ECU first in BENCH, then continue with reading and writing directly via OBD.
• Make subsequent tuning operations faster and more direct, without accessing the ECU in BENCH again.
• Extend the programming service to your End-Users with Powergate on supported applications.

With KESS3, you can now read and write via OBD the MD1CS001 "Locked" ECUs fitted to 1.5L and 2.0L diesel engines from the B37 and B47 families.

The new OBD protocol therefore integrates with the BENCH mode already available: first unlock the Bosch MD1CS001 "Locked", then read and write from the diagnostic port with KESS3 and Powergate.

This release is the first in a series of developments dedicated to these ECUs.

The new protocol is available to KESS3 users with CAR OBD + BENCH/BOOT activation and an active subscription.

Powergate users can access the protocol after unlocking with KESS3, provided that the relevant Powergate Manager has CAR BENCH/BOOT activation.
