Alientech KESS3 Add Boot Unlock for VAG MD1CS014 Locked ECU

Alientech KESS3 released new BOOT unlock and BENCH protocols for Bosch MD1CS014 "Locked" ECUs — Audi and Volkswagen.

KESS3 expands its coverage of latest-generation Audi and Volkswagen diesel vehicles equipped with 3.0 V6 TDI engines, from 2021 onwards.

Update highlights:

• Unlock protected Bosch MD1CS014 ECUs using the dedicated Glitch BOOT procedure
• Perform writing operations in BENCH mode after unlocking
• Work directly through the ECU connector without reopening it for subsequent operations
• Coverage for Audi A4, A5, A6, A7, Q5, Q7, Q8, S5, S6, S7 and SQ5, and Volkswagen Touareg

With KESS3, you can now work on protected Bosch MD1CS014 ECUs fitted to Audi and Volkswagen models with 3.0 V6 TDI diesel engines, produced from 2021 onwards.

The initial operation requires opening the ECU and unlocking it using the dedicated BOOT Unlock protocol with the KESS3 Unlock Module accessory.

Once unlocked, you can also perform reading and writing operations in BENCH mode, connecting directly to the ECU connector, without having to open it again for subsequent operations.

The practical benefits for your workshop:

• Work in your workshop on Bosch MD1CS014 "Locked" ECUs fitted to Audi and Volkswagen 3.0 V6 TDI models from 2021 onwards.
• Unlock the ECU in BOOT with KESS3 Unlock Module.
• Perform reading and writing operations in BENCH mode after the initial unlock, without reopening the ECU.

With KESS3 and KESS3 Unlock Module, you extend your capabilities on the latest-generation Audi and Volkswagen models, managing new operations in-house on 3.0 V6 TDI diesel engines, even when protected ECUs are fitted.

ECUDesk 2.4.0.0 Restores ECU Files to Factory Settings

ECUDesk released a new function: RESTORE STOCK (ECUDesk ECU chip tuning software 2.4.0.0, desktop client and Telegram Mini App).

Returns an already modified file to factory values: switched-off DTCs come back on, and EGR/DPF/CAT and other feature patches are removed. Maps, coding and all other data stay untouched.
The button appears only when the ECUDesk database holds an original of the same software version that matches the file everywhere except the tuning changes.

Shown on every subscription; using it requires Premium. Use it first, before any other feature.

After the restore, features can be applied again. The file name gets _stock.
