Bosch MD1CS003 Original files | 1.5 BlueHDI tuning files | Instant download |

The MD1CS003 ECU was installed on the 1.5 BlueHDI engines from 2018 onwards. The 1.5 HDI uses the latest EU 6.3 standards with Adblue, DPF, EGR.

There are two important strings to match in the file, the Bosch SW number starting 10SW or 1037 and then the SW Upgrade number which starts 96 and ends 80.

Generally it’s enough to match only the Bosch SW number because PSA don’t mix versions with the same number.

If the file you find has a different car name or car brand, but the SW Upgrade and Bosch SW variant are both identical, you are ok to use the file. This is because the same sw was used across many brands and platforms.
