How does ALIENTECH KESS3 Unlock Module Complete Kit work ?

Sep15

The ALIENTECH KESS3 Unlock Module Complete Kit is designed to unlock selected protected Bosch MD1/MG1 (MDG1) ECUs so that KESS3 can access their internal memories and perform ECU programming in BOOT mode. It was introduced with KESS3 Upgrade 3.50 in September 2026.

How it works ?

1. Remove and open the ECU
The supported ECU is removed from the vehicle and opened so the technician can access the ECU circuit board. BOOT mode requires direct access to the ECU’s internal electronics.

2. Connect the Unlock Module
The KESS3 Unlock Module is connected between the KESS3 and the ECU using the supplied adapter board, ribbon cable, jumpers and VFL3 connection cables. The complete kit includes the 14AS00T11S hardware module and 14AS00T12S adapter.

3. Perform the BOOT Unlock procedure
Using the appropriate KESS3 protocol, KESS3 communicates with the protected ECU through the Unlock Module and performs the required unlock/patch procedure. This allows the previously protected ECU memories to become accessible.

4. Read / write / backup the ECU
After successful unlocking, KESS3 can access the ECU in BOOT mode for supported operations, including:

  • ECU identification
  • Full read
  • Write/programming
  • Complete backup
  • Access to supported memory areas

5. BENCH operation may be available afterward
For supported ECU versions, Alientech has also released BENCH protocols. After the initial BOOT unlock, the ECU can subsequently be accessed directly through its connector in BENCH mode, meaning the ECU does not necessarily need to be opened again for every subsequent programming operation.

Simple workflow

Vehicle → Remove ECU → Open ECU → KESS3 Unlock Module → BOOT Unlock → ECU Memory Access → Read/Backup → Modify File → Write → Reinstall ECU

Supported ECUs

The current Alientech release includes models such as MD1CS003, MD1CS069, MD1CP007, MD1CS012, MG1CS042, MD1CS004 (HW80), MG1CS031, MD1CP006, MD1CS005 and MG1CS002. Coverage is protocol-dependent and mainly concerns protected Bosch ECUs used in vehicles from around 2021 onward.

Important: the Unlock Module is an accessory for KESS3, not a standalone ECU programmer. The relevant KESS3 CAR BENCH/BOOT activation and active subscription are required for the new unlock protocols.

For a product page, a concise description could be:

Unlock Protected Bosch MD1 & MG1 ECUs with KESS3
The ALIENTECH KESS3 Unlock Module Complete Kit enables professional BOOT-mode unlocking of supported Bosch MD1/MG1 ECUs. After unlocking, KESS3 provides access to ECU memory for reading, writing and full backup, helping workshops complete ECU programming in-house.

Is FormulaFlash Compatible with the Bosch MD1CS003 ECU?

Aug18

One of the most common questions we receive from European workshops and ECU tuning professionals is:

“Can FormulaFlash read and write the Bosch MD1CS003 ECU?”

The short answer is:

Yes. FormulaFlash currently supports the Bosch MD1CS003 ECU in BENCH mode for supported vehicle applications.

However, compatibility depends on the specific ECU hardware version and supported protocol. Before purchasing, we always recommend verifying your ECU information to ensure compatibility.

What Is the Bosch MD1CS003 ECU?

Because of its widespread use across European vehicles, MD1CS003 has become one of the most frequently requested Bosch ECUs among FormulaFlash users.

How Does FormulaFlash Support MD1CS003?
FormulaFlash is a professional ECU and TCU programming platform that supports multiple communication methods across different ECU families, including:

OBD
BENCH
BOOT
For the Bosch MD1CS003 ECU, the currently supported programming method is BENCH mode.

BENCH programming provides a stable and reliable communication method while keeping the ECU enclosure sealed, making it an ideal solution for professional workshops.

Current support includes:

ECU Identification
ECU Read
ECU Write
Checksum Correction
Professional ECU Programming Workflow
(Actual available functions may vary depending on the ECU hardware version and software protocol.)

Why Is BENCH Mode Used for MD1CS003?
Customers often ask why FormulaFlash supports OBD, BENCH, and BOOT, yet MD1CS003 currently uses BENCH mode.

The answer is simple:

Each ECU family has its own communication protocol.

While FormulaFlash supports OBD, BENCH, and BOOT across its complete protocol library, the Bosch MD1CS003 protocol is currently designed for BENCH programming, providing a safe and stable programming environment for supported applications.

Flex Failed to Write PSA SID807EVO by OBD Solution

May7

Problem:
Magic Motorsport Flex programmer reads Peugeot 307 SID807EVO ECU ok, but can not write the modified file by OBD. It is a keyless system.

Error autohrization from ECU failed.


Solution:

The keyless ones have to see the key in the emergency key position to allow operation.

Key must be in a coil detection area, that is why you couldn’t read.

Put key in the correct compartment and try again. Put key in the slot beside the steering.

Also if manual put it in 1st drivers seat belt on and hazards

Optional Solution:

Try leaving the ignition on even when it asks you to turn it off, or disconnect the battery for a while and try again.

Play around with ignition on off timings. Don’t wait for flex, when it says ignition on click ok and then wait around 5-5 seconds before you turn it on. If you’ve done any resets with diag make sure ignition off for 2 minutes before you connect flex
SID87 EVO if password protected can be done obd, if non password protected boot only,, should still connect to update to latest software.

User feedback:
Disconnected battery for some time did the fix and worked
