CG FC200 Boot Unlock and Read/Write for VAG MD1CS004

Successfully locked a Volkswagen Bosch MD1CS004 H80 TC298 locked ECU using CG FC200 programmer.

In boot mode using the DME unlock adapter + new BD25 cable for FC200.

The DB25 cable is a must for locked ECU. The new DB25 adds a GPT-4 wire for encrypted ECUs. The 0-ohm resistor needs to be desoldered.

Unlock ok.

Read ok.

Write ok.

Checksum correction with FC200.

Everything is fine. The car started and is running after flashing the modified file.

AutoTuner Adds DCU102 Support for Jumper, Boxer and Ducato

Autotuner programmer released new OBD protocol for CITROËN, PEUGEOT & FIAT LCV- Visteon DCU102 goes live on OBD Virtual Read & Boot Normal Read!

Expand your commercial van calibration capabilities on your AutoTuner Tool with dual programming support for the Visteon DCU102 ECU. Covering the iconic Citroën Jumper, Peugeot Boxer, and Fiat Ducato powered by 2.2 HDi and 2.2 JTD engines, this protocol lets you choose between convenient OBD Virtual Read directly through the diagnostic port and Boot Normal Read on the ST10F276 MCU with automatic checksums correction.

Autotuner is pleased to announce that the Visteon DCU102 engine control unit is now officially supported via OBD Virtual Read (VR) and Boot Normal Read (NR) on your AutoTuner Tool. This protocol covers European light commercial vehicles across Citroën, Peugeot, and Fiat models from 2002 to 2006, specifically the Citroën Jumper, Peugeot Boxer, and Fiat Ducato powered by the durable 2.2 HDi and 2.2 JTD diesel engines.

ECU Spotlight: What You Might Not Know

Why does a French and Italian commercial van carry an engine management system developed by an American automotive electronics giant?

The answer is the Visteon DCU102 (Diesel Control Unit). Visteon was Ford’s own electronics division until it became independent in 2000, born from the same Ford–PSA diesel partnership that shared engines between both groups. It manages the 2.2 HDi / 2.2 JTD of the 2002 Jumper and Ducato, and the Ford link goes even deeper on the 2006 Jumper and Boxer: their 2.2 HDi is in fact Ford’s own 2.2 "Puma" turbodiesel.

Built around the STMicroelectronics ST10F276 16-bit microcontroller, the DCU102 is made for workhorse duty: delivery fleets, campervans and ambulances. These vans came off the line at Sevel Sud in Atessa, Italy, a Fiat–PSA joint venture often described as Europe’s largest light commercial vehicle plant.

One ECU, three brands, two generations of vans: now you can read and write them all with your AutoTuner Tool.

How to Fix Renault Master SID321 AdBlue Warning

Problem: After read and write Renault Master SID321 ECU with Autotuner programmer, adblue message pops up for 1 second then disappears, only happens on first ignition cycle after locking the van, did resets, EOBD clear too and battery off, have tried different solutions still the same problem, any ideas?

Solution:
Unplug the SCR module.

Reset the SCR module: before writing, disconnect the SCR module, write the file, and then reset all car — done!

If it’s after 2022, the SCR module is behind mud cover — need to be disconnected! Anyway make "start authorisation" from diagnostic and should be ok.

User feedback:
Disconnected SCR module at the end fixed, never had to before! But even with the 0 mileage the van still started and ran ok.

KESS3 Enables BENCH Tuning for Audi MG1CS163 ECUs

Alientech KESS3 released new boot unlock protocols for Bosch MG1CS163 locked ECUs- Audi, Bentley and Cupra.

KESS3 expands its coverage of high-performance sports and luxury vehicles equipped with 2.5 TFSI/TSI and 6.0 W12 TwinTurbo petrol engines.

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

Once this procedure is complete, you can perform writing operations directly in BENCH mode using the existing protocol, connecting to the ECU connector. The initial unlock does not need to be repeated: for subsequent operations, you can work in BENCH without opening the ECU again, simplifying your daily workshop activities.

The practical benefits for your workshop:

• Work on Bosch MG1CS163 "Locked" ECUs fitted to Audi, Bentley and Cupra 2.5 TFSI/TSI and 6.0 W12 TwinTurbo engines.
• Unlock the ECU in BOOT using KESS3 Unlock Module.
• Perform writing operations in BENCH mode after the initial unlock, without reopening the ECU.

With KESS3, expand your possibilities for working on high-performance sports and luxury cars, extending your workshop services to engines of particular interest to the tuning market.
