Introduction to the OBDLink CX
The OBDLink CX is a professional-grade Bluetooth OBD-II adapter engineered specifically for BIMCO/BimmerCode compatibility and broader vehicle diagnostics. Designed for enthusiasts and professionals who demand reliable, fast, and accurate data, the CX bridges the gap between your vehicle's ECU and your smartphone or tablet with minimal fuss.
Whether you're coding BMW modules, reading live sensor data, or clearing fault codes, the OBDLink CX delivers a stable, low-latency connection that budget adapters simply can't match.
Key Features
- Bluetooth 4.0 (BLE) — Low-energy, fast pairing with iOS and Android devices
- BimmerCode & BimmerLink Certified — Officially recommended for BMW/MINI coding apps
- Multi-protocol support — Compatible with all OBD-II protocols including CAN, ISO, VPW, and PWM
- Secure by design — No open Wi-Fi hotspot; paired device-only communication
- Compact form factor — Low-profile design that won't obstruct your dash or door
- No power switch needed — Auto sleep/wake to preserve your vehicle's battery
- Compatible with OBDLink app — Full access to enhanced OEM diagnostics beyond generic OBD-II PIDs
What Vehicles Is the OBDLink CX Compatible With?
The OBDLink CX is compatible with all OBD-II compliant vehicles (petrol and diesel) manufactured from:
- Australia: 2006 onwards (most makes)
- USA: 1996 onwards
- Europe: 2001 onwards (petrol), 2004 onwards (diesel)
It is particularly well-suited for BMW, MINI, and Rolls-Royce vehicles when used with BimmerCode or BimmerLink, offering access to proprietary coding and diagnostic functions not available through generic OBD-II tools.
Supported Apps
The OBDLink CX works seamlessly with a wide range of diagnostic and coding applications:
- OBDLink App (iOS & Android) — Free, feature-rich diagnostics with enhanced OEM support
- BimmerCode — BMW/MINI module coding (officially supported adapter)
- BimmerLink — Advanced BMW/MINI live data and diagnostics
- Torque Pro (Android) — Popular third-party OBD dashboard app
- Car Scanner ELM OBD2 (iOS & Android) — Extended PID support for many makes
- DashCommand — Performance monitoring and data logging
How to Set Up the OBDLink CX
Step 1: Plug In the Adapter
Locate your vehicle's OBD-II port — typically found under the dashboard on the driver's side. Plug the OBDLink CX firmly into the port. The LED indicator will illuminate to confirm power.
Step 2: Enable Bluetooth on Your Device
On your iOS or Android device, navigate to Settings > Bluetooth and ensure Bluetooth is turned on. You do not need to pair the CX via the system Bluetooth settings — pairing is handled within the app.
Step 3: Download Your Preferred App
Install the OBDLink app (or BimmerCode/BimmerLink) from the App Store or Google Play.
Step 4: Connect Within the App
Open the app and navigate to the adapter/connection settings. Select OBDLink CX from the list of available devices. The app will establish a BLE connection automatically.
Step 5: Start Diagnosing
Once connected, you can read fault codes, view live data streams, perform resets, or begin module coding (if using BimmerCode). Always ensure your vehicle's ignition is in the ON position (engine running or key-on) before scanning.
Reading & Clearing Fault Codes
Fault codes (DTCs — Diagnostic Trouble Codes) are stored by your vehicle's ECU when a system detects an anomaly. The OBDLink CX allows you to:
- Read stored DTCs — Identify current faults affecting your vehicle
- Read pending DTCs — Catch intermittent issues before they trigger the check engine light
- Clear DTCs — Reset fault codes after repairs (note: underlying issues must be resolved first)
⚠️ Important: Clearing codes without addressing the root cause will result in the fault returning. Always diagnose before clearing.
Live Data & Monitoring
One of the most powerful features of the OBDLink CX is real-time data monitoring. Via the OBDLink app, you can track:
- Engine RPM, coolant temperature, and throttle position
- Fuel trims (short and long term) for diagnosing fuelling issues
- O2 sensor readings for exhaust and emissions diagnostics
- Battery voltage and charging system health
- Boost pressure (on supported turbocharged vehicles)
- Transmission temperature (on supported vehicles)
Data can be logged and exported for further analysis — ideal for tracking down intermittent faults or monitoring performance modifications.
BMW & MINI Coding with BimmerCode
The OBDLink CX is the officially recommended adapter for BimmerCode — the leading BMW/MINI coding app. Coding allows you to enable or disable factory-fitted features that are locked by default, such as:
- Enabling video-in-motion for the iDrive system
- Activating cornering lights or adaptive headlights
- Disabling the seatbelt chime or start/stop system default
- Enabling sport displays and lap timers
- Customising door lock/unlock behaviour
⚠️ Coding note: Always back up your vehicle's coding data before making changes. Incorrect coding can affect vehicle systems. The OBDLink CX's stable BLE connection is critical here — connection drops mid-coding can cause issues.

Troubleshooting Common Issues
Adapter Not Connecting
- Ensure the OBD-II port has power (ignition ON)
- Force-close and reopen the app, then retry connection
- On iOS, check that the app has Bluetooth permission in Settings
- Try unplugging and re-plugging the adapter
Slow or Dropped Connection
- Reduce distance between adapter and device
- Avoid interference from other Bluetooth devices
- Ensure your device's OS and the app are up to date
No DTCs Found But Check Engine Light Is On
- Some manufacturer-specific codes require enhanced OEM support — use the OBDLink app for broader coverage
- Confirm the vehicle is OBD-II compliant
BimmerCode Not Detecting Adapter
- Confirm you are using the OBDLink CX (not a clone or incompatible adapter)
- Check BimmerCode's supported adapter list in the app settings
- Reinstall the app if the issue persists
Tips for Getting the Most Out of Your OBDLink CX
- Keep the adapter plugged in during short trips — the auto-sleep feature prevents battery drain
- Use the OBDLink app for enhanced diagnostics — it unlocks manufacturer-specific PIDs beyond generic OBD-II
- Log data before and after modifications — baseline comparisons are invaluable for tuning
- Update firmware via the OBDLink app — ScanTool.net periodically releases updates improving compatibility
- Store in a protective case — the CX is compact; keep it safe when not in use
Frequently Asked Questions
Is the OBDLink CX compatible with my iPhone?
Yes. The CX uses Bluetooth Low Energy (BLE), which is fully compatible with iOS devices. Unlike older Bluetooth Classic adapters, no workarounds are required.
Can I use the OBDLink CX on multiple vehicles?
Yes. Simply unplug from one vehicle and plug into another. Re-connect via your app as normal.
Does the OBDLink CX work with Android Auto or Apple CarPlay?
The CX connects to diagnostic apps, not directly to Android Auto or CarPlay. However, some compatible apps (like DashCommand) can display data on your head unit.
Will it drain my car battery?
No. The OBDLink CX features an intelligent auto-sleep mode that draws minimal current when the vehicle is off.
Is it compatible with electric vehicles (EVs)?
The CX supports OBD-II protocols used by many EVs and hybrids, but EV-specific data (e.g., battery state of health) depends on the app and vehicle make. Check your app's EV compatibility list.
