Mercedes-Benz gearbox & TCU families

Cloning, renewal, programming and matching are different operations. This catalogue identifies the controller families we can assess; the exact unit and available original data determine the job.

Mercedes FDCT · P051300

“Start enable was not issued.” On affected FDCT units, this can accompany a drive-authorization problem, sometimes following low voltage. We assess the fault and module data, with data repair where applicable, before recommending replacement.

BEFORE WE BOOK

Send the VIN, TCU label, hardware/software numbers and fault report. The transmission family alone does not confirm service compatibility. Electronic work is assessed separately from internal mechanical repairs.

MD1 / MG1 and newer secured engine controllers need an individual hardware, software and access check.

Original unit + donor unit

Recoverable original data and compatible donor hardware determine the available route. Some cases require virginizing and adaptation rather than a direct clone.

BEFORE WE BOOK

Send photos of both labels and say whether the original unit still communicates. A donor with a similar casing or connector is not enough to establish compatibility.

What we can help with

  • Battery-management system fault assessment
  • Inspection of supported battery electronics

Common enquiries

  • Battery-management warning or communication fault

  • A battery assembly has been recommended for replacement

Assessment before a replacement.

A battery warning does not by itself confirm a failed BMS. The battery condition and relevant vehicle faults need to be checked together.

BEFORE WE BOOK

Send the battery label and diagnostic report first. Cell condition, physical damage and protection-system status determine whether electronic repair is appropriate.

Before booking your Mercedes-Benz

Can you clone every controller with this family name?

No. Hardware, software, immobilizer generation, donor compatibility and readable original data determine the available operation. Send both labels and the scan report.

What is the difference between cloning and virginizing?

Cloning transfers supported original data to a compatible replacement. Virginizing / renewal prepares a supported used unit for a separate matching or personalization process. Programming or coding configures software and vehicle functions.

What should I send for a quote?

The VIN, fault codes, original and donor labels, symptoms and work already completed. Tell us whether the original control unit still communicates.

Controller coverage references

Family listings were checked against manufacturer documentation on 2 November 2026. They identify assessment categories and do not replace a check of the actual unit.
