Supplier information checked on 11 October 2026. Flashtec lists EMP unlock, voltage-glitch unlock and mail-in options for selected Bosch MDG1 ECUs. Its September 2026 release page describes the equipment and risks of the two workshop methods. The earlier claim that Flashtec only offered a contrasting mail-in approach no longer reflects its published options.

Flashtec and CMDFlash

Flashtec says its EMP method uses separate electromagnetic-pulse hardware. Its voltage-glitch option involves more component handling and, according to the supplier, greater physical or electrical damage risk. These are supplier descriptions; this article does not establish which method is safer for a particular ECU.

The published mail-in list names the following Bosch units:

  • PSA: MD1CS003 and MG1CS042
  • VAG: MD1CS004 H80, MG1CS163 and MG1CS031 H80
  • VAG/Porsche: MG1CS002 H80 and MG1CS008
  • Fiat/Iveco: MD1CS069
  • BMW: MG1CS201 and MG1CS024
  • Land Rover: MD1CP007 and MG1CS028
  • Kia/Hyundai: MD1CS012
  • Porsche: MG1CP007 and MG1CS047
  • Ford: MD1CS005

Flashtec's mail-in instructions require CMDFlash ECU identification and an active subscription with at least seven days remaining. The casing may need to be opened. Check eligibility and shipping instructions directly with the supplier.

Magicmotorsport Flex

The Flex 8.3.0.0 announcement names BMW Bosch MG1CS049 TC298 and Isuzu Bosch MD1CS089 TC299, with Boot Glitch and Bench modes and Full Master or Full Slave licensing. That release concerns the listed control units; it does not establish coverage for every MDG1 ECU.

Send us the registration and ECU identification before booking. We can check the applicable supplier protocol, required equipment and whether an unlock service is available for that unit.
