What this service is
A Bentley ECU clone is the fastest route back to driveable when your original DME has failed but the car is otherwise sound. Rather than buying a dealer-programmed replacement and paying for VIN write, key sync, and immobilizer alignment, we read the original ECU’s complete memory map, clone it onto a compatible donor, and ship it back ready to plug in and start. No PIWIS, no ODIS, no trip to the dealership.
Clone-only service — you supply both ECUs. This service requires two units: your failed original ECU and a matching donor ECU (same manufacturer part number and hardware revision), both supplied by you. We clone your original’s data onto your donor and ship it back. Not sure which donor matches? Email us a photo of your failed ECU label first and we confirm compatible part numbers before you buy a donor.
How to source a compatible donor
The donor does not need to come from a car with the same VIN or mileage — after cloning it carries your original data. What it does need to match exactly:
- Same manufacturer part number on the label
- Same hardware revision suffix (AA / AB / AC, or PCB rev number where printed)
- Same Bosch / Continental / Delphi / Denso hardware code where applicable
Good donor sources: eBay Motors, Car-Part.com, local salvage yards with parts-lookup, and make-specific forums / Facebook groups. Send us the label photo before you buy and we’ll pre-clear it.
Bentley ECU platforms we support
Bentley shares most of its DME architecture with the Volkswagen Group (Audi D3/D4/D5) and BMW (N74 V12 on Mulsanne), so our workflow covers the common platforms cleanly:
- Bosch ME7.1.1 / ME9.1 — Continental GT and Flying Spur W12 6.0 twin-turbo (2003-2016)
- Bosch MED17.1.1 / MED17.1.6 — Continental GT V8 4.0 twin-turbo, Flying Spur V8
- Bosch MED17.1.27 — Bentayga 4.0 V8
- Bosch MEVD17.2.6 — Mulsanne N74 V12 (BMW-shared architecture)
- Bosch EDC17CP44 / EDC17CP54 — Bentayga diesel 4.0 TDI (V8)
USA-market Bentley models covered
- Continental GT / GTC (2003–present) — W12 and V8
- Continental Flying Spur (2005–2013) and Flying Spur (2014–present)
- Mulsanne (2010–2020) — 6.75 twin-turbo V8
- Bentayga (2016–present) — W12, V8, Hybrid
- Arnage, Azure, Brooklands (older platforms)
Common part-number prefixes
We match by Bosch DME number (4E0 907 xxx, 3W0 907 xxx, 4W0 907 xxx) where 4E/3W/4W are the Bentley/VW Group platform prefix, or by the Bosch hardware code on the label (0 261 S0x xxx). Matching the exact hardware revision is what allows the clone to start without component protection headaches.
How the clone works
- Email us the label first (recommended). Send a photo of your failed ECU’s part-number label and we confirm the exact donor part numbers that will work — before you spend money on a donor.
- You source a matching donor. Buy a compatible used ECU yourself through eBay Motors, Car-Part.com, or a salvage yard with parts-lookup. Must match manufacturer part number and hardware revision.
- Mail us BOTH units together — your failed original ECU AND the matching donor you sourced, shipped in the same box with your order number. Prepaid return label available on request.
- We bench-read your original — full flash plus EEPROM (immobilizer secret, VIN, mileage, learned values) captured intact. Most “dead” units can still be read on the bench.
- We clone onto your donor — your donor is blanked, then your original’s flash and EEPROM are written one-for-one.
- Bench verification — every clone is simulated before it ships. Immobilizer bytes, VIN string, and odometer confirmed to match.
- We ship your cloned donor back — 24-hour turnaround from when both units arrive. Plug in, turn the key, drive.
What’s preserved
- Immobilizer secret → existing keys still work
- VIN → cluster, body computer, infotainment stay aligned
- Mileage → zero odometer discrepancy
- Adaptations, throttle learn, fuel trims, injector codes
- Component protection pairing where applicable
Pricing and warranty
$200 flat. Clone work only — donor ECU must be supplied by you. Nationwide mail-in. 24-hour bench turnaround. 12-month warranty. Send a photo of your ECU label plus year and model — we confirm compatibility before you ship.
