What is Module Cloning?

Module cloning is the process of transferring all the critical data from your faulty original module (FEM/BDC/CAS/EWS) to a donor replacement module. This includes:

• ISN (Immobiliser Secret Number) – ensures your keys continue to work
• VIN (Vehicle Identification Number) – maintains vehicle identity
• Mileage data – preserves accurate odometer reading
• Key synchronisation data – all your existing keys work immediately
• Vehicle configuration (FA) – maintains all settings and options
• Central locking and comfort settings

BMW Modules We Clone:

🔧 FEM (Footwell Electronics Module) – F-series BMW (F20, F30, F10, F11, F25, etc.)
• Immobiliser control and key authentication
• Central locking and alarm systems
• Interior lighting and comfort functions
• Power distribution and relay control
• Common failure: blown relay causing no start, water damage, internal component failure

🔧 BDC (Body Domain Controller) – F-series BMW modules
• Similar to FEM but different internal architecture
• Controls body electronics and immobiliser
• Key programming and authentication
• Common failure: internal faults, water ingress, component damage

🔧 CAS (Car Access System) – E-series BMW (E60, E70, E90, E91, F-series transition)
• CAS3, CAS3+, CAS3++ variants
• Immobiliser and key management
• Central locking and alarm control
• DME/DDE synchronisation via ISN
• Common failure: internal electronics fault, no communication, key not recognised

🔧 EWS (Electronic Immobiliser) – E-series BMW (E36, E38, E39, E46, E53)
• EWS2, EWS3, EWS3+ variants
• Original BMW immobiliser system
• Transponder key authentication
• ECU synchronisation
• Common failure: circuit board failure, water damage, component failure

Common Symptoms Requiring Module Cloning:

❌ No start – engine cranks but won’t fire
❌ “Key not detected” or “Key not recognised” message
❌ Steering wheel locked, immobiliser active
❌ Central locking not working
❌ No communication with module during diagnostics
❌ Water damage to module location
❌ Internal relay failure (common on FEM/BDC)
❌ Tamper dot active, module locked

Why Choose Cloning Over Buying New from BMW?

💷 Cost Savings:
– BMW FEM/BDC new: £800-£1200 + programming + new keys (£200-£400 each) = £2000+
– Our cloning service: Used module (£100-£300) + cloning service = Typically under £500

🔑 Keep Your Keys:
– BMW requires all new keys when replacing modules (expensive and inconvenient)
– Cloning preserves your existing keys – they work immediately

⏱️ Faster Turnaround:
– BMW dealer: Order parts, wait for delivery, book appointment, reprogram entire car
– Our service: Clone module, install, drive away – often same day

📊 Preserve Vehicle History:
– Mileage preserved accurately
– Original VIN maintained
– Service history integrity protected
– No dealer flags for “major component replacement”

How Our BMW Module Cloning Service Works:

1. **Diagnosis** – We diagnose your BMW to confirm module failure
2. **Source Donor Module** – We can help source a compatible used module, or you can provide one
3. **Module Unlocking** – We unlock both your original and donor modules using specialist equipment
4. **Data Extraction** – We extract all critical data from your faulty module (even if “dead”)
5. **ISN Transfer** – We transfer the ISN and key synchronisation data
6. **VIN Programming** – Correct VIN written to donor module
7. **Full Cloning** – All configuration data (FA) transferred
8. **Testing** – Module tested to ensure keys work and all functions operate
9. **Installation** – Cloned module installed in your vehicle
10. **Final Coding** – Gateway and body programming completed

What We Need from You:

• Your faulty original module (FEM/BDC/CAS/EWS)
• A compatible donor module (we can source this for you)
• At least one working key for the vehicle OR the engine ECU
• Matching part numbers between original and donor (critical for compatibility)

Important: Part number compatibility is essential. We verify all part numbers before proceeding to ensure successful cloning.
