Bosch MD1CS004 — supported tools
Bosch MD1CS004 — ECU reading, writing and tool support. AutoTuner: Bench (read, write); AutoTuner: OBD (virtual read, write); BitBox: Bench (read, write); Flex: OBD (read, write); Flex + Korhex: Boot (read, write); Flex + Korhex: Bench (read, write); PCMflash: Bench (read, write); Abrites ECU Programming Tool: Bench (read, write). Coverage is limited to the variants and conditions stated for each tool, including required unlocking. Check the diagrams section for Bench and Boot pinout availability; wiring must match the ECU variant and programming tool.
Compatibility depends on ECU HW/SW, protocol and active licence. A tool missing from this list does not imply lack of support.
- Read (type unspecified)
- Write
Bosch MD1CS004; TC298TP; Audi; PCB v4.2; manual variant, page 124
Abrites manual v4.2 describes reading and writing in Bench; compatible AVDI/Distribution Box equipment and authorizations are required. Match the exact connector/PCB variant. Do not extend coverage to other HW/SW versions or other modes.
- Read (type unspecified)
- Write
MD1CS004 TC298 H80; after Mail-in Unlock
Perform Bench identification and confirm eligibility first. Supported after the unlock service.
- Virtual Read
- Write
VAG 2.0 TDI; supported HW/SW versions
Virtual read (VR) supplies a stock file, not a backup of a modified ECU. File availability depends on software identification.
- Read (type unspecified)
- Write
VAG 2.0 TDI; variants supported without additional unlock service
Connect through the ECU connector without opening its housing. H80 requires separate verification and Mail-in Unlock.
- Read (type unspecified)
- Write
- Checksum
Bosch MG1/MD1 BENCH; VAG; compatible unprotected variants
Bench memory/EEPROM read and write with checksum correction on writing. Requires Scanmatik SM2/SM2 Pro/SM3 and automatic power control. This module excludes protected versions introduced in the second half of 2020; Gen2 requires a separate protocol. Match the wiring to the MCU and HW/SW identification.
- Read (type unspecified)
- Write
- Checksum
VAG; MG1/MD1 Gen2 FID 582; TC298/TC299, after BSL unlock
ECU opening and BSL Voltage Glitch unlock are required first, followed by Bench Flash/EEPROM read/write with checksum correction. Requires Scanmatik SM2 Pro/SM3, updated drivers and the manual circuit or BITS002 adapter. Boot is the unlock step; no Boot read/write capability is asserted.
- Operations unspecified
Audi; Bosch MD1CS004 TC298; Bench compatibility listing
The list confirms Bench support. Check the exact ECU variant for the available operations.
- Operations unspecified
Audi A3 (8V) 2.0 40 TDI, 190 HP, 2019; historical list 4.8.0.0
Historical compatibility from the 2020 list. Modes are listed without operation details. Check the current Flex version before use.
- Read (type unspecified)
- Write
- Checksum
MD1CS004 TC298, HW 05L907309AA; VAG 2.0 TDI 2022–2024; after RFT
Map read/write/checksum; RFT licence/service required.
- Read (type unspecified)
- Write
- Checksum
MD1CS004 H80 TC298; Flex 8.27.0.0, Boot Glitch
Boot Glitch: internal Flash read/write/checksum; EEPROM read/write, full backup. FLS0.20 or Full FLS0.5 required. No public official Boot wiring photograph found.
- Read (type unspecified)
- Write
MD1CS004 H80 TC298; after Korhex unlock
Bench read/write after unlocking; this does not imply ordinary Bench access to a locked ECU.
- Read (type unspecified)
- Write
- Checksum
VAG 2.0 TDI; TC298; module 92
Module 92: ROM and EEPROM read/write, ROM checksum. Scanmatik 2/Pro/3 or Dialink; ECUs produced after mid-2020 may be unsupported. Bench pinout, pages 31: T91: +12V 6,50; GND 2. H22: CAN-L 52, CAN-H 51. H30: CAN-L 30, CAN-H 31. Diagram v3: CAN-L 13, CAN-H 14; this variant is not identified as H80. Match the connector variant and pin-numbering orientation to the diagram.
