Programming for Bosch MD1CS004 & MD1CS104 ECUs Now Available

Written on 30 June 2026. Published on 30 June 2026.

We are now offering programming services for Bosch MD1CS004 and MD1CS104 engine control units for a wide range of VAG Group vehicles as well as selected Ford and MAN models. This enables professional tuning and calibration of numerous 2.0 TDI Common Rail engines meeting EU6 and EU6.2 emission standards, as well as Ford 2.0 EcoBlue engines. Following a one-time unlock procedure (Mail-in Unlock, requiring the ECU to be shipped for unlocking), the control unit can subsequently be read and programmed directly via Bench mode. No further shipping is required for future modifications.

Advantages:

• Long-term secured ECU unlock
• Reading & programming via bench mode
• Support for numerous VAG 2.0 TDI EU6 / EU6.2 and Ford 2.0 EcoBlue engines
