MB Citaro 7.7TDI — Siemens/Continental MCM21 — 0024461735002 0384482235001 0704481535001 OM936LA
ECU tuning and emission-solution file for this exact calibration · 299hp / 1200nm · 2021
About this file
This page covers one exact calibration: Siemens/Continental MCM21 with software 0024461735002 0384482235001 0704481535001 OM936LA, as indexed on the MB Citaro 7.7TDI. Work is done on your own original read — we do not send a generic file for the controller family, because two vehicles sharing a controller can carry different maps, limiters and diagnostics.
Send the file exactly as your tool saved it and tell us which tool produced it. You get the modified file back in the same format, with the checksum corrected, ready to write. Turnaround is 1–3 hours for the solutions listed as available below.
If your readout shows a different software number from the same family, use the version list at the bottom of the page — every calibration we have indexed has its own page.
Everything on this page is reference information. Not finding your exact version here does not mean we cannot do it — a solution can be developed for any calibration. Create an order on the file service and send us the original read.
What can be done on this ECU
These are the services offered for the Siemens/Continental MCM21 and their list prices. Ordering several in one file is cheaper — the calculator below applies the bundle rules.
| Service | Price | Notes |
|---|---|---|
| DPF/FAP Delete | 150 € | To delete the DPF, the AdBlue/SCR system must also be removed - please select the SCR/AdBlue OFF option as well if needed. You can perform the coding yourself via Xentry (instructions will be provided after placing the order) - in this case reading the ACM (AdBlue) module is not required. If you cannot perform the coding, you must read and attach files from both control units: ACM ECU (AdBlue) and MCM ECU (engine). You must also physically disconnect the DPF pressure sensor and the exhaust temperature sensors. |
| EGR/AGR Removal | 95 € | |
| SCR/AdBlue OFF | 160 € | If you want to remove only the AdBlue system and keep the DPF filter active, you must read and attach files from both control units: ACM ECU (AdBlue) and MCM ECU (engine). If you also want to remove the DPF, you have 2 options: disconnect the ACM plug (no reading needed) and perform the coding yourself via Xentry (instructions provided after placing the order); or, if you cannot perform the coding, attach reads from both control units - ACM and MCM. You must also physically disconnect the AdBlue injector plug, the AdBlue pump and the NOx sensor. |
| Stage 1 tuning file | 160 € | Please visit our website tuning catalog to see final results after Stage 1: https://auto-remap.com/catalog/trucks |
| Throttle Valve TVA Disable | 95 € | |
| Swirl valve/Flaps OFF | 95 € | |
| DTC's selectivity OFF | 70 € | |
| Checksumm correction | 50 € | Checksumm correction: select this option ONLY if you really need checksumm and your device not do it automatically, because this option cost additional money! |
| Back to ORIGINAL file (restore file to original) | 30 € | Please select this option only if you really need to recovery all changes to original. In case if your attached file after our checking content original changes, order will be completed and the cost of the checking will be deducted from your account!!! Because we are loosing time on checking and comparing it with original database= this is same like price return to original. |

Other software versions on Siemens/Continental MCM21
Reading this platform: ACM and MCM
Switching AdBlue off on this platform always needs both controllers read — the ACM and the MCM.
For a DPF + AdBlue delete there are two routes. Read the MCM and unplug the connector from the ACM: the job works, but the vehicle then needs Xentry coding afterwards, and we send you the instructions for it.
Or read both the MCM and the ACM. No coding is needed afterwards — this is the route to take if Xentry is not available to you.
