Engine ECU, transmission control unit, EIS or CAS — send it in and we transfer the original data 1:1 onto an identical replacement unit. The immobiliser is preserved, the written report is included. All makes, all ECU types.

Even a seemingly dead unit can often still be cloned. Through dedicated read modes (BENCH, BOOT, BDM) we read the memory directly — even when the unit no longer establishes any communication in the vehicle. As long as EEPROM and flash are intact, we secure your data.
We name the fixed price in advance — based on the findings, not on a hunch. Should the clone not succeed after all, we charge the diagnosis hour only, with no cloning costs. The risk stays with us, not with you.
No. In a clone the replacement unit takes over the immobiliser coupling together with the VIN, the mileage reference and every adaptation value. The vehicle recognises it as the original — re-learning at a dealership is not required.
We have been working on vehicle electronics in the Hardegsen workshop (Lower Saxony, Germany) since 1978. Three master-level diagnostic tool chains — XENTRY (Mercedes), ODIS (VW Group) and ISTA (BMW/Mini) — combined with bench programming hardware (KTAG, MagicMotorSport, Autotuner) cover almost every modern ECU platform.
Same software the official dealerships use — XENTRY, ODIS, ISTA. SCN coding, FBS programming, variant coding included.
BDM, JTAG, Tricore Bench and Boot Mode for the entire Bosch / Continental / Siemens / Delphi range. We work on the chip — not just via OBD.
Every clone is accompanied by a written report: original VIN, target VIN, data regions, checksum, and the engineer's signature.
DHL insured, tracked. Return shipping is included in the fixed price — no hidden costs after the work is done.
Original data 1:1 onto a matching replacement unit. Immobiliser preserved. All popular Bosch / Continental / Siemens platforms.
Mercedes 722.9, ZF 6HP/8HP, VW DSG DQ250/DQ200/DQ500. Adaptation values transferred or reset cleanly.
Service clone with backend authentication, key data transferred, vehicle remains startable without re-coding the key.
Steering lock control unit cloned including FBS coupling. Especially common after EZS failure on W203, W211, W639, W906.
Crash data cleared, virgin condition restored. Cost-effective alternative to replacement after an accident.
Forensic mileage documentation; original mileage retained. Legal handling per § 22b StVG.
If your control unit is not listed, send us the part number and the failure description — we will check feasibility within one working day.
| Your situation | Best solution | Why |
|---|---|---|
| Control unit defective, data still readable | Cloning onto a replacement unit | Original data transferred 1:1, immobiliser preserved, no re-learning at an authorised dealer |
| Component damage on the circuit board | Repair of the original unit | Substance and original data stay with the unit — often the route that preserves the most value |
| Used control unit bought, vehicle will not start | Cloning your original data onto the used unit | Without the data transfer the immobiliser does not match — the clone makes the used unit yours |
| Memory destroyed, data no longer readable | A straight answer: cloning is not possible | A new unit plus learning then remains the route — we tell you after the diagnosis, before any costs arise |
| Vehicle needed urgently | Send-in service | Feasibility usually assessed on the same working day, 2–4 working days processing, insured return shipment |
Whether your specific device type is cloneable is shown by our cloneability check for your control unit.
You can source a matching used unit yourself and send it in together with your original — or we take over the sourcing through our parts channels. If you source it yourself, we check before cloning whether the donor unit really matches and is functional.
The part number is on the type label of the control unit — on engine control units usually a Bosch, Continental, Delphi or Denso number (for example “0 281 …” on Bosch diesel units) plus the vehicle manufacturer's own part number. A phone photo of the label is enough for our advance check; we agree the photo with you after your inquiry.
What counts is the identical hardware number; the software level may differ, because the software is transferred along with the clone. If the hardware revision is too far apart, we tell you before you place the order — not afterwards.
The control unit is addressed on the workbench through its original connector, without opening the housing. The standard route for many current Bosch and Continental generations (for example EDC17, MED17) — gentle, fast, no soldering.
At start-up the processor is put into a service mode that allows direct memory access. Required on generations that are locked in bench mode — the housing is opened and a contact point on the board is wired up.
Direct access to the debug interface of the processor — our route on older generations (for example EDC16) and on units that no longer establish any communication. As long as the memory chips are intact, the data can still be rescued this way.
Which method is needed is decided by the device family, not by a wish for a cheaper route. And the honest limit: if the memory chip itself is destroyed, no method can bring the data back. Which device families we work on is set out under the control unit types we clone.
Send us the vehicle, the ECU type and the failure pattern via our waiting-list form. We assess feasibility and quote a fixed price as soon as capacity allows.
Remove the ECU, pack it safely and send it by parcel. We can provide a shipping label. Important: no loose connectors, anti-static packaging recommended.
Once received, we run a full diagnosis. Backup of the original data, transfer onto a replacement unit or repair. All data regions are verified before return.
The cloned ECU is checked for readability, VIN binding and data completeness. You receive a written report with every step.
Insured return via DHL — return shipping included. Installation notes and warranty document are part of the package.
Yes — that is precisely the advantage of cloning over replacing. The original VIN binding, immobiliser keys and SCN coding are transferred 1:1. Your existing keys keep working. No re-coding at a dealership is required.
Yes. Cloning is a workshop technique that transfers your existing licensed data onto identical replacement hardware. Mileage from the instrument cluster is handled in accordance with § 22b StVG and documented. We do not perform any odometer manipulation.
Typical turnaround is 2–4 working days from arrival of the parcel. We confirm receipt the same day, run the diagnosis the next working day, and ship the result with an insured DHL return label.
We quote a fixed price before any work starts — based on ECU type, brand and complexity. Engine control units typically start at the level of a standard repair, transmission units and CAS/EIS modules sit slightly higher. Return shipping and the written report are always included.
Not always. For many platforms we can supply a tested matching replacement. If you have your own donor, we use it. Either way the inquiry process clarifies this within one working day.
Inquiries in English, German, French, Dutch, Polish, Turkish and Ukrainian are welcome. Please use the waiting-list form or email — we reply in the order requests arrive during workshop hours (Mon–Fri).
