Generate NCD2/3 coding 2.0/3.0 from FA & SVT

Generate NCD2/3 Coding 2.0/3.0 from FA & SVT is a specialized remote/online service for modern BMWs (primarily G-series, i-series, Neue Klasse-era models with iDrive 7/8/8.5/9, ~2021+).

What It Is and Why It Exists

BMW introduced Secure Coding (also called NCD Secure Coding) around 2021 to lock down ECU coding.

• NCD stands for New Coding Data (or Non-Volatile Coding Data) — these are the parameter files (often .ncd or CAFD-related) that define how each ECU/module (e.g., BDC, FEM, HU_MGU, KAFAS, etc.) is configured.

• NCD 2.0 (main version for most 2021–2024 G/i models) and NCD 3.0 (newer iteration for latest ID8/ID9 hardware, 2024+, stricter security) require digitally signed NCD files. Unsigned or manually edited files are rejected by the vehicle's security system — coding fails or reverts.

• Purpose of Secure Coding: Prevent unauthorized/third-party modifications, protect proprietary software/IP, ensure safety (e.g., ADAS, eCall, emissions), maintain warranty compliance, and stop "free" activation of paid options (e.g., full-screen CarPlay, tow bar coding, region changes).

Traditional DIY coding (E-Sys/NCS Expert on older F/E-series) no longer works on secure modules — you need signed NCD files generated/matched to the specific vehicle.

FA (Fahrzeugausstattung / Vehicle Order): The complete factory equipment list/options tied to the VIN (like a detailed build sheet in .fa or .xml format).

SVT (Sachverhaltstabelle): The current ECU/software parts table (module versions, hardware IDs, status).

These two files are the "fingerprint" of the vehicle. Services use them to generate compatible/signed NCD files (full set for all relevant ECUs) that the car will accept.

How the Service Works (Typical Process)

1. Customer Side:

   • Connect to car via ENET cable + OBD → Launch E-Sys (or similar tool like ESysUltra/LauncherPRO).

   • Read/export current FA (and optionally modify it for retrofits/custom options, e.g., add 5AP for antidazzle, enable hidden features).

   • Read/export SVT (current or "Target SVT"/programming SVT).

   • If CAFD files are missing (e.g., FFFFFFFF), use "Detect CAF for SWE" in E-Sys.

2. Upload:

   • Send FA + SVT files (sometimes VIN + modified FA) to the service provider.

3. Generation:

   • Backend tool processes FA/SVT to create a full set of matching NCD/CAFD files (often signed or "secure-compliant").

   • Time: 3–15 minutes (24/7 automated services exist).

   • Options: OEM (original FA) or Modified FA (for changes/retrofits).

4. Coding:

   • Receive NCD zip/set via email/download.

   • In E-Sys: Connect to vehicle → Load NCD into relevant CAFD blocks (right-click → New → NCD → select file) → Execute "Code NCD".

   • Often done module-by-module or in batches.

   • Some services include secure tokens, SFA files, or repair packs.

5. Post-Coding: Backup, test, clear faults if needed.

Many providers offer remote sessions (screen share) for full guidance or end-to-end coding.

Common Use Cases

• Region conversion (imported cars: change to EU/US coding).

• Retrofits (add hardware like tow bar, cameras, ambient lighting → proper coding).

• Feature activation (full-screen Apple CarPlay/Android Auto, disable ads/start-stop, enable hidden menus, M Performance options).

• Disable unwanted functions (e.g., speed limit assist warnings).

• Post-repair or aftermarket ECU work.

• VO (Vehicle Order) coding where direct FDL edits are blocked.

NCD 2.0 vs. 3.0

• 2.0: Covers ~95% of modules in 2021–2024 models; widely supported by generators.

• 3.0: Newer/updated for latest hardware (ID9, Neue Klasse previews, some 2024+ facelifts); potentially stricter signing or different format — fewer services explicitly support it yet, but generators like BimmerFSC advertise 2.0-3.0 compatibility.
