Question:
If Xhorse Multi prog can clone an MD1CS003 PSA ECU?
Answer:
The Xhorse Multiprog can clone a Bosch MD1CS003 PSA ECU as long as the unit is not locked. These ECUs are used in diesel vehicles from Peugeot, Citroën, Opel, and Toyota, and share an architecture with other modern controllers. The main chip is an Infineon Aurix TC298, which in certain versions is protected with OTP zones and lock bits that prevent cloning.
When the ECU belongs to the Bosch series with 3xx part numbers, it is usually unlocked and can be read and written in bench mode with Multiprog and other tools such as KESS3, FoxFlash, CG FC200, or OBDSTAR DC706.
However, units with 4xx and higher part numbers are usually locked, making cloning impossible with any tool available on the market.
Therefore, before attempting to clone an MD1CS003, it is essential to check the unit’s Bosch part number. If it corresponds to an unlocked series, Multiprog can perform the cloning without problems. If it is a locked ECU, there is no practical solution other than physically replacing the processor, which is complex and expensive.
