Bosch ME7.x Engine ECU Cloning — VW, Audi & Bentley Mail-In Bench Service, Immobilizer Preserved

Dropped a used ME7 ECU into your 1.8T, VR6, 2.7T, or Bentley W12 and it just cranks without catching? Mail in your original plus the donor and we clone the complete data across on the bench — immobilizer, VIN, coding, and adaptations — so the replacement runs plug-and-play and your existing keys still work.

  • A complete bench read and verify pass of both units before a single byte is written
  • Checksum-correct write plus a powered communication test on a stable, regulated supply before return

Will This Fix My Problem?

Honest answer: here's exactly what this service fixes — and what it doesn't.

Fixes:

  • ✓Used or salvage-yard ME7 ECU installed and the engine cranks but never fires
  • ✓Immobilizer-active warning or a stored immobilizer fault after an ECU swap
  • ✓Original ECU failing from water ingress, corrosion, or a bad repair but still responding — cloned before it dies
  • ✓Dealer or specialist quotes a coded replacement ECU on a Mk4, B5, TT Mk1, or Bentley Continental
  • ✓Second-hand 2.7T or W12 ECU that needs your car's identity written to it
  • ✓You want the replacement module fully ready BEFORE it goes into the car

Won't fix:

  • ✗Does NOT remove the immobilizer — this service preserves it. ME7 immobilizer removal is our separate vw-audi-immo-delete-vin-program service; do not order this page expecting an immo-off.
  • ✗Does NOT include emissions edits of any kind — no DPF, EGR, AdBlue/SCR, catalyst, lambda, or readiness-monitor defeat work, on any platform, for any reason
  • ✗Does not include the donor ECU — you source a matching used unit and we verify the part number first
  • ✗Does not revive an original that is internally dead, burnt, or will not respond on the bench — that is our ecu-advanced-recovery-service, and a completely unreadable original cannot be cloned from
  • ✗Does not cover the other VW Group families — Continental Simos is vw-audi-simos-immo-clone, MED9 is vw-audi-med9-immo-clone, EDC16 and EDC17 diesel and PCR2.1 each have their own pages, and MED17 / ME17 cloning is vw-audi-bosch-ecu-clone
  • ✗Does not repair or clone the instrument cluster or BCM2 body module — those are vw-audi-cluster-clone and vw-audi-bcm2-clone
  • ✗Does not bypass proof of ownership, and does not fix a no-start caused by fuel, ignition, sensors, wiring, grounds, or a weak battery

Clone (this page) versus immo-off (the other page) — do not order the wrong one

Both services touch ME7, and they do opposite things. This page is the CLONE: your original's immobilizer relationship is carried onto the donor, so the factory security system stays fully active and your existing keys keep working. That is what almost every road car wants. The immo-off lives on our vw-audi-immo-delete-vin-program page, which permanently removes the immobilizer requirement from the module for a swap, standalone, or orphaned build with no cluster or keys left to satisfy. If you are not sure which you need, send the VIN and a photo of the ECU label and a technician will tell you before you pay anything.

Shipping Instructions

These details are also emailed to you the moment your payment clears.

Verify first: text or email us your VIN plus clear photos of your original ME7 ECU label and the donor's label — a technician confirms the Bosch and VAG part numbers are a compatible match, and on Bentley W12 cars tells you whether one or both engine ECUs need to come, before you ship. Then send both units to PO Box 120241, Arlington TX 76012 if you ship USPS — or 1009 Oakwood Ln # 120241, Arlington TX 76012 if you ship UPS or FedEx (UPS and FedEx cannot deliver to a PO Box). We read, clone, and communication-test on the bench, then ship everything back via the return option you pick at checkout (Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95).

What to include in your box

  • Your original ME7 ECU (as long as it powers up we can usually read it) AND the matched donor ECU
  • Bentley W12: both engine ECUs if a technician told you the car uses a pair
  • Year, make, model, engine code, and transmission (e.g. 2002 Audi S4 B5 2.7T biturbo, 6-speed)
  • VIN of the vehicle
  • The Bosch number AND the VAG part number off BOTH ECU labels — we pre-verify the match
  • What is wrong now: dead original, cranks-no-start after a swap, water damage, failed repair
  • Proof of ownership — title, registration, or bill of sale (required for all immobilizer work)
  • Your name, return address, and an email address or phone number we can reach you at

Frequently Asked

Still have a question? Text us — replies in minutes.

What is a Bosch ME7 ECU and which cars use it?
ME7 is the Bosch Motronic engine-management generation VW Group used from the late 1990s through the end of the 2000s. You will find it on the VW Golf Mk4 and GTI, Jetta Mk4, New Beetle, Passat B5 and B5.5 (1.8T and VR6), Audi A4 B5 and B6, A6 C5, TT Mk1, the S4 and RS4 2.7T biturbo, the allroad, and on the 2003–2010 Bentley Continental GT and Flying Spur W12. The variant — ME7.1, ME7.1.1, ME7.5, ME7.5.10 — is printed on the ECU label.
Does the immobilizer stay active after you clone it?
Yes, completely. That is the entire point of this service. Your original's immobilizer relationship is carried onto the donor, so the factory security system keeps working, your existing keys keep starting the car, and nothing needs coding at install. If you want the immobilizer REMOVED instead — for a swap, a standalone build, or an orphaned platform — that is our separate vw-audi-immo-delete-vin-program service, not this one.
Do you cover Bentley Continental GT and Flying Spur?
Yes — the 2003–2010 Continental GT, GTC, Flying Spur, and related W12 variants run Bosch ME7.1.1 and are covered at the same $250 flat price. One thing to check first: some W12 applications run a pair of engine ECUs rather than one, so send clear photos of every ECU label you can reach plus the VIN, and a technician will tell you exactly what needs to ship before you pack anything.
Do you supply the donor ECU?
No — you source a used donor from eBay, a salvage yard, or a parts recycler, and we verify it before you spend money. Match both numbers on the label: the Bosch number and the VAG part number. Send us photos of your original's label, the donor listing, and your VIN, and a technician confirms whether the pair will clone cleanly. That verification is free and it happens before you buy.
My original ECU is water-damaged. Is it too late to clone it?
Not necessarily, and this is the case where speed matters. If the module still powers up and responds on the bench, we can usually pull the data out even when the board is corroding — which is exactly why we tell people to clone a dying ECU before it stops responding entirely. If it is already completely dead, there is nothing to read, and the job moves to our ecu-advanced-recovery-service instead.
Will I need a dealer visit or a key re-learn afterwards?
On a clean clone, no. The donor carries your original's complete identity, so the car sees the module it has always seen — no coding appointment, no key programming, no cluster adaptation. Some learned values such as idle and fuel trims relearn themselves over normal driving. If your specific job has any install-side step, we tell you about it in the notes that ship back with the modules.
Do you offer tuning, DPF, EGR, or emissions edits with the clone?
No. Auto Module Lab performs no emissions edits of any kind — no DPF, EGR, AdBlue/SCR, catalyst, lambda, or readiness-monitor defeat work — on any platform, for any customer, for any stated reason. This service is identity and immobilizer data transfer only. If your original ECU carries an aftermarket tune, tell us before you ship so we can discuss what does and does not carry across.
How much is it and how does the mail-in work?
It is $250 flat. After a technician verifies your VIN and both ECU labels, you mail the modules to Auto Module Lab in Arlington, TX — USPS to the PO Box, or UPS/FedEx to the street-addressed form of the same box, since UPS and FedEx cannot deliver to a PO Box. We clone on the bench, run a powered communication test, and ship both units back with tracking at the return speed you pick and pay for at checkout: Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95. This is a mail-in bench service only.
