ð BMW Bosch MG1CS049 DME Replacement / Data Transfer Service â Including Post-2020 Locked ECUs ð
Is your BMW Bosch MG1CS049 DME (Engine ECU) faulty, damaged or in need of replacement?
Have you sourced a compatible replacement MG1CS049 but need the required vehicle-specific data transferred from your original DME?
We can professionally read and transfer the required data from your original Bosch MG1CS049 to a compatible replacement unit, providing a cost-effective alternative to purchasing and programming a brand-new DME.
We can now work with the later security-protected Bosch MG1CS049 TC298 DMEs, including units manufactured after June 2020.
These later BMW DMEs incorporate additional Bosch/BMW security which previously made bench access considerably more restricted.
Our specialist equipment now provides bench access to these locked MG1CS049 units, including:
The MG1CS049 contains important vehicle-specific and security information, meaning that simply fitting a used MG1CS049 from another vehicle does not necessarily provide a working replacement.
Our service allows us to read the required information from your original MG1CS049 DME and transfer the applicable data to a compatible replacement unit.
Depending on the particular DME and software version, this can include:
The aim is to prepare the compatible replacement DME with the required information from your original unit so that it can be used as a replacement in your vehicle.
The Bosch MG1CS049 is primarily associated with BMW's S58 3.0-litre TwinPower Turbo petrol engine. ECU databases identify MG1CS049/DME86S0 hardware with S58B30 engine variants.
â ïž IMPORTANT: ECU fitment can vary depending on production date, engine version, market and DME hardware.
Please check that âMG1CS049â is shown on your original DME before purchasing. If you're unsure, send us your registration/VIN and a clear photograph of the DME label and we can confirm compatibility.
For this service we normally require:
Compatibility between the original and replacement units is extremely important.
Where possible, we recommend matching the relevant:
If you're unsure whether your replacement DME is compatible, please send us clear photographs of the labels from both units before purchasing.

Q: What is a Bosch MG1CS049?
A: The Bosch MG1CS049 is a petrol engine management ECU/DME used particularly with BMW's S58 3.0-litre TwinPower Turbo engine, including modern BMW M applications. MG1CS049 hardware includes the Bosch/BMW DME86S0 family using a TC298 processor.
Q: Can you work with post-June-2020 locked MG1CS049 DMEs?
A: Yes. We can now bench-read and write the later security-protected MG1CS049 TC298 units.
Q: Is this the same as cloning an older BMW DME?
A: Not exactly. The later post-2020 MG1 DMEs incorporate additional security, so the process differs from a conventional older ECU cloning procedure. We access the original DME on the bench and read/transfer the applicable DME, EEPROM, FLASH and immobiliser/ISN information required for the replacement.
Q: Which engine is the MG1CS049 normally fitted to?
A: MG1CS049 is particularly associated with the BMW S58 3.0-litre twin-turbo petrol engine, including S58B30 variants.
Q: How do I know whether my vehicle has an MG1CS049?
A: Check the identification details on your original DME for MG1CS049. Alternatively, send us your registration/VIN and a clear photograph of the DME label and we can confirm compatibility before purchase.
Q: Do I need to send both DMEs?
A: Yes. For this replacement data-transfer service we normally require your original MG1CS049 and a compatible replacement MG1CS049, unless we have agreed to supply the replacement unit.
Q: Does the replacement DME need exactly the same part number?
A: We strongly recommend matching the relevant Bosch/BMW hardware and part numbers wherever possible. If the numbers differ, please send us clear photographs of both DME labels before purchasing so compatibility can be checked.
Q: Can you supply a replacement MG1CS049?
A: In some instances, yes. We may be able to source or supply a compatible replacement DME at an additional cost. Please contact us with the details from your original unit.
Q: Can you recover the data if my original DME is faulty?
A: In many cases, yes. An ECU can be faulty while its required data remains readable. However, the necessary information must still be recoverable from the original DME. Please contact us first if your original unit is completely dead, badly water damaged, burnt or physically damaged.
Q: Will my existing engine software or remap be retained?
A: Where the relevant FLASH/calibration data is readable and appropriate for transfer to the compatible replacement unit, the original software data can be retained. Please let us know when sending the units if retaining modified software is particularly important.
Q: Will the replacement DME require coding afterwards?
A: In most cases, no additional vehicle coding should be required where the required data has been successfully transferred to a correctly matched replacement DME. However, these later MG1 DMEs incorporate additional BMW/Bosch security and the process differs from conventional older ECU cloning. Depending on the particular vehicle, DME software and circumstances of the original failure, additional vehicle-side programming, synchronisation or setup may occasionally be required after installation.
Q: Is MG1CS049 the same as MG1CS024 or MG1CS201?
A: No. MG1CS049, MG1CS024 and MG1CS201 are different Bosch MG1 DME variants. The service must be matched to the actual DME fitted to the vehicle.
Q: How quickly is the service completed?
A: We offer same-day turnaround and dispatch where possible for units received before 12:00 PM.
Q: Can I bring the DMEs directly to you?
A: Yes. Workshop drop-off is available at our Scunthorpe premises, with same-day service available where possible.
Q: What return delivery service do you use?
A: Completed units are securely packaged and returned via Royal Mail Tracked 24.
