How to Activate Hidden Renault Features with Renolink
Your Renault or Dacia likely has more features than you think — some of them hidden or disabled by default from the factory. With Renolink 2.12, you can unlock and customize hidden functions that dealerships rarely talk about, turning your car into a smarter, more responsive machine.
From auto-folding mirrors to DRL (Daytime Running Lights) changes and dashboard tweaks, this guide will walk you through exactly how to discover and activate secret Renault features using Renolink.
Let’s explore what your car is really capable of. 🚗✨
What Are Hidden Renault Features? 🔍
Hidden or inactive features are functions that exist in your car’s firmware but are disabled by default – often for regional regulation reasons or cost-saving tactics.
With Renolink, you can activate many of these using your laptop and an OBD2 interface. These are not “hacks” but factory-deactivated settings.
Some examples include:
- Auto-folding side mirrors when locking
- Comfort indicator / 3-blink lane change
- Rear wiper with reverse gear
- Daytime Running Light (DRL) options
- Needle sweep on ignition
- Auto lock at speed (central locking over 10-15 km/h)
- Deactivation of seatbelt warning chime
- Turn signal behavior and brightness
- Follow-me-home lighting control
- Rear parking sensor tone and volume
Before activating, make sure your car supports that particular function — Renolink can only enable features that your model’s UCH/ECU firmware already supports.
What You Need to Get Started 🧰
To activate hidden Renault features, you’ll need:
- A Windows laptop (Windows 10 or 11, 64-bit)
- Renolink 2.12 software properly installed and activated
- USB OBD2 interface compatible with Renolink
- Your vehicle (Renault or Dacia from approx. 2006–2020)
- Fully charged car battery or battery maintainer

Step-by-Step: How to Enable Hidden Features
Step 1: Connect Renolink
- Turn ignition to ON (engine not running)
- Connect the USB interface between your laptop and the car’s OBD2 port
- Launch Renolink on your laptop
Step 2: Select the Correct Module
- Use the module selector to locate the UCH or BSI system
- Load the module data to gain access to coding menu
- Always double-check your model and firmware version
Step 3: Backup the Original Configuration
⚠️ Very important: Always back up the current EEPROM or configuration file before changing options.
If anything goes wrong, you’ll need this to restore normal operation.
Step 4: Open Feature Coding Section
- Navigate to the “coding” or “custom settings” tab
- A list of toggles or hexadecimal coding values will appear
- Use contextual help (if available) or a feature chart to identify which string controls what
Some high-level tools auto-label these for you (e.g., “Auto Fold Mirrors: ON/OFF”).
Step 5: Edit and Write Changes
- Toggle the desired feature to “Enabled” or adjust values as needed
- Click “Write” to send the changes to your ECU
- Wait for confirmation screen – do not disconnect midway
Step 6: Test the Feature
- Restart ignition and manually test the function
- For lighting tweaks, step out and visually inspect
- For auto-mirror or door locks, repeat lock/unlock cycle
Congrats — your car just leveled up. 🎉

Common Questions
Will changing features void my warranty?
Maybe. Dealers may log or detect ECU changes if they scan in detail. Do this on vehicles out of warranty or for personal-use modifications.
Can I activate features on Dacia cars too?
Yes — many features also exist in Dacia models like Duster, Sandero, and Logan.
Is this different from dealership software?
Yes, Renolink gives you access to hex editing and customizations not typically available at dealerships.
Can I undo any changes?
Absolutely. Just load your saved EEPROM/flash backup and write it back if needed.

Renolink is far more than just a diagnostic tool — it’s a key to unlocking your car’s full potential. By accessing hidden or region-locked features, you can customize your Renault or Dacia to behave exactly how you want it to.
