Volkswagen Engine Computer (ECM / ECU / DME) Clone to a Donor — Every VW 2002–2026, Mail-In
Your Volkswagen's engine computer failed and the used one you bought cranks but never starts? One flat price clones your original onto the donor — VIN, immobilizer, coding and adaptations carried over — for every VW engine ECU from 2002 to 2026. Look up your ECU by year, model or part number, and if the car needs an on-car software step afterwards we do it remotely with ODIS over your J2534 interface.
Sending several modules? Add them all — one box, one return-shipping charge.

VW Engine ECU Clone (Any Model): the short answer
Auto Module Lab clones Volkswagen engine computers — ECM, ECU or DME — for every VW model sold in the US from 2002 to 2026 at a flat $350. You mail your original ECU and a donor with the same full part number to our Arlington, Texas bench; we copy the original's VIN, immobilizer data, coding and adaptations onto the donor, typically within 24 hours of arrival, so the replacement installs with the factory immobilizer intact. Covered families include Bosch ME7, MED9, MED17/ME17 and MG1, Continental Simos, and the EDC15/16/17 diesel controllers. Our VW ECU part-number lookup identifies your controller by year, model or label, and any on-car ODIS software adaptation afterwards is done remotely over J2534.
How It Works
Three simple steps. Hundreds of mail-in jobs completed for shops, locksmiths, and DIY pros.
Pay & Get Address
Click "Order Now", pay securely online. We email shipping address + instructions within minutes.
Ship Your Module
Pack per the instructions and ship to Arlington. USPS goes to our PO Box; UPS and FedEx must use the street address. Your prepaid inbound label arrives by email — shipping to us costs you nothing.
Get It Back Fast
Work typically completed within 24 hours of receipt. Ships back next business day at the return speed you chose at checkout — standard to overnight. Tracking emailed.
What You Get
- Your original VW ECU's complete data cloned onto the donor — VIN, immobilizer data, coding and learned adaptations
- Factory immobilizer kept fully active — the car trusts the module the way it trusted the original
- Part-number verification by VIN and label before you buy a donor, free
- Bench communication test of the donor before it ships back
- Both modules returned, with a note of what was read and written
- Typical 24-hour bench turnaround once both modules are here
- A clear answer, before any charge, if your original cannot be read
Compatibility
Confirm your part matches one of the variants below before ordering. Not sure? Text us a photo and we'll verify.
Your ECU part number is printed on the module label as three groups — for example 06J 906 026 CK. The first nine characters identify the controller family and are what our lookup matches; the trailing letters select the calibration, and a donor must match the FULL number, including those letters. Use the VW ECU part-number lookup to find your family by year and model, then text us a photo of the label with your VIN before buying a donor — we confirm the match for free, usually within minutes. The lookup is linked below the chips.

Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Used Volkswagen ECU installed and the engine cranks but never starts (immobilizer mismatch)
- Original ECU with water, corrosion or connector damage whose board still reads
- Replacing failing ECU hardware while keeping the factory immobilizer and all learned values
- A failed MED9.1 on a Mk5 GTI, Jetta GLI, Passat or Eos — the most common VW ECU failure we see
- A dealer-quoted new ECU plus online adaptation you would rather avoid, when a readable original exists
Won't fix:
- An original ECU that is completely dead and unreadable — a clone needs a readable source; see the dead-module recovery service
- Removing the immobilizer for a swap or standalone build — that is an immo-off service, not a clone
- A no-start caused by the immobilizer chain outside the ECU: a damaged instrument cluster, a key with no transponder, a broken antenna ring
- Fuel, ignition, sensor, wiring and timing faults — the car has to be diagnosed first; a clone copies data, it does not fix the car
- A donor with a different full part number — a calibration mismatch is not something a clone can bridge
- Emissions edits of any kind (not offered)
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
Codes that commonly lead here
What each code means, and what it does not prove on its own.
A stored code is evidence, not a verdict. Every code below can also be set by wiring, connectors, grounds, power supply, or the component the module is trying to drive. Rule those out before you ship anything — or text us the codes and freeze-frame and we will tell you honestly whether the module is even a suspect.
| Code | Meaning | What it does not prove |
|---|---|---|
| P0601 | Internal control module memory checksum error. | Points at the ECU's own memory and is the most defensible reason to replace one — but confirm the code is current, not a one-time write interruption, before buying a donor. |
| P0604 / P0605 | Internal control module RAM / ROM error. | Strong evidence of a failing ECU when it returns after a clear. A low battery during a flash can log the same codes once on a healthy module. |
| P0606 | ECM / PCM processor fault. | The ECU reports its own processor failed a self-test. Repeating P0606 with no other explanation is the classic case for cloning the original onto a donor; a single occurrence after a jump-start usually is not. |
| P062F | Internal control module EEPROM error. | The memory that holds the immobilizer and adaptation data. Act on it quickly — a clone needs that data to still be readable. |
| P1570 | Engine start blocked by the immobilizer. | On a car with a USED ECU this is the mismatch a clone fixes. On a car with its ORIGINAL ECU it points at the cluster, the key or the antenna ring, not the ECU — diagnose before shipping anything. |
| U0100 / U0001 | Lost communication with the engine control module / CAN bus. | Can be a dead ECU, but far more often a power, ground or CAN wiring fault. Check supply and ground at the ECU connector before concluding the module failed. |

Repair vs used vs replacement
Four ways out of this failure, compared honestly.
| Path | What you actually pay for | Programming needed | Immobilizer and your data | Main risk |
|---|---|---|---|---|
| Clone your original onto a donor (this service) | A used ECU you source, plus one flat bench fee to make it yours. | None in most cases — the donor leaves the bench carrying your VIN, coding and adaptations. Some cars want a short on-car ODIS step, which we run remotely. | Kept. Factory immobilizer stays active; every learned value survives. | An original that cannot be read, or a donor with the wrong full part number. Both are checked before anything is charged. |
| Used ECU installed as-is | The cheapest part up front. | Yes — it still belongs to the donor car and will crank without starting until the immobilizer relationship is dealt with. | Lost. You inherit the donor's VIN, coding and adaptations. | A module of unknown history that may fail the same way; the car does not run until it is cloned or adapted anyway. |
| New ECU through a dealer | A new part plus the dealer's online adaptation and coding labour, and a tow if the car is not driveable. | Yes — dealer online session to marry the new unit to the car. | Configured fresh to your VIN; learned adaptations start from zero. | Highest-cost path, parts availability on older platforms, and dealer scheduling controls your downtime. |
| Immobilizer-off | A bench edit that removes the immobilizer requirement from the ECU. | None, but the factory anti-theft is gone. | Immobilizer disabled by design. Appropriate for legitimate swaps and standalone builds, not for a daily driver you want secured. | Loses the theft protection the clone keeps. Sold on separate pages, with proof of ownership. |

Cloned, installed, and the car still wants a software step? We finish it remotely.
Most cloned VW ECUs start and drive the moment they are plugged in. Some cars still ask for an on-car step the bench cannot do — a software version management (SVM) update, module coding, or a basic-settings adaptation such as throttle body or readiness. Instead of a dealer visit, book a VW/Audi remote session: you plug a J2534 pass-thru interface into the car, we connect to it and run the factory ODIS software from here. $250, scheduled around your bay time, and the same session covers coding after any other module replacement.
