Engine and transmission module cloning

Your dead module’s identity copied onto a matching donor, so the vehicle accepts it without a dealer visit.

From $249 — confirmed against your VIN

How it is done

  • You post us the unit and we send it back ready to fit.

What's included

  • Copying your original module’s data onto a matching donor, bench-verified before it ships.
  • Your original returned unmodified.

What it doesn't cover

  • The donor module, unless you asked us to supply it.

Have this ready

  • Both units — original and donor — labelled, with the VIN.

How long

We confirm the part-number match the day it arrives, before any work.

Will it work on your vehicle?

Coverage depends on the exact year, model and part number — not just the make. Send us the VIN and we confirm on the tool before anything is quoted or ordered.

What it works on

BMW · Mercedes-Benz · VW Group, 131 engine and 20 transmission modules, model years 2000–2024. ⛔ Coverage is per part number, not per brand — send yours and we confirm before you ship.

Questions we get

What if the clone cannot be done?
You pay return shipping only, and your original comes back exactly as it arrived.
Does the donor have to be identical?
The part number must match exactly. Cloning onto a mismatched donor destroys it, so we check first and refuse if it is wrong.
Why clone instead of buying new?
A cloned module keeps your vehicle’s identity, so it plugs in without a dealer visit — often the difference between a bill in the hundreds and one in the thousands.

What we can clone

Coverage is per part number, not per brand — send us yours and we confirm before you ship.

Shipping, and what happens if it fails

  • Free return shipping, every job

    Coming back to you costs you nothing, whatever the outcome.

  • Free prepaid inbound label on jobs $199+

    Below that, you post it to us and we cover the return.

  • No clone, no fee

    If we cannot clone your module you pay return shipping only, and your original comes back exactly as it arrived.

  • Your original is never modified

    We read it. We do not write to it, and it comes home either way.

  • Exact part-number match required

    A donor whose part number differs is not "close enough" — cloning onto the wrong one destroys it. We check before anything is touched.

  • You hear from us the day it lands

    We confirm what we have, what it needs and when it ships back before we start.

  • Written terms on our work

    You see them before you agree. Nothing verbal.

What to put in the box

  1. Anti-static bag first, then a padded box — a bare module in a jiffy bag arrives damaged.
  2. Label each unit ORIGINAL or DONOR, and write the VIN on both.
  3. Include the working key for BMW CAS/FEM and Mercedes EIS jobs — the module cannot be matched without it.
  4. Print your confirmation and put it in the box so we can match it to your job.
  5. Photograph the part number before you seal it. It settles any question later in one message.
