How to replace Instrument Cluster Mercedes Benz W211/ W219 Overlay with AMG 320kmh

Upgrading the instrument cluster on your Mercedes W211 or W219 to an AMG-style 320km/h overlay is one of the most effective visual enhancements—especially if you’re running a powerful V8 Kompressor engine. This upgrade doesn’t just give your dashboard a sportier AMG appearance; it also reflects the performance hidden beneath your hood.

However, simply installing the new 320km/h faceplate or cluster won’t make it work out of the box. Unlike some other car brands, Mercedes vehicles use a high-security architecture that requires coding or adaptation before the new cluster can function properly. Without this crucial step, your speedometer, RPM gauge, or even cluster lighting may behave incorrectly—or not respond at all.

In this guide, AutoExPlain will walk you through the entire process, from physically replacing the overlay to the technical steps required to recalibrate and encode your instrument cluster—ensuring full functionality and factory-level precision. Whether you’re a DIYer or a pro technician, this article has the insights you need to complete the upgrade successfully.

What Is The Instrument Cluster Overlay?

The instrument cluster overlay is the printed plastic dial face that sits on top of the gauge needles inside the instrument cluster. It displays the speed in kilometers per hour (km/h), tachometer RPM scale, fuel level, and temperature. In AMG models, this overlay is different—it shows a 320 km/h speedometer scale instead of the standard 160 km/h, 260 km/h or 280 km/h.

What Tools Do You Need to Replace Mercedes Instrument Cluster (320 km/h Upgrade)

Upgrading the instrument cluster in a Mercedes-Benz, especially to an AMG-style 320 km/h version, is not a simple plug-and-play process. Due to the vehicle’s security protocols, Mercedes clusters require proper coding and configuration to work correctly. Below is a detailed list of tools you will need to carry out the replacement and ensure the cluster functions as expected.

Before you begin, make sure you have the following:

• Replacement AMG 320 km/h cluster overlay (OEM or high-quality aftermarket)
• Plastic trim removal tools
• Torx screwdriver (T20 or T25 depending on model)
• Gloves (to avoid fingerprints on the overlay or lens)
• Clean, anti-static workspace
• Microfiber cloth
• Soft pry tools or needle puller (for safely removing gauge needles)

How To Replace The Instrument Cluster Overlay For Mercedes W211 W219 Upgrade On AMG V8 Kompressor 320km/h

Step 1: Disconnect The Battery

Always disconnect the vehicle’s battery before working with the instrument cluster. Wait at least 10 minutes after disconnection to allow capacitors to discharge fully. This prevents triggering fault codes or damaging components.

Step 2: Remove The Instrument Cluster

• Use a trim removal tool to gently pry off the decorative dashboard trim.
• Unscrew the Torx bolts securing the cluster.
• Pull the cluster out slowly and disconnect the wiring harness at the rear.

Step 3: Open The Cluster Housing

• Place the cluster face-down on a soft cloth to avoid scratching the lens.
• Release the clips holding the back cover and remove the housing carefully.
• Remove the front clear plastic lens and gently lift the cluster face.

Step 4: Remove The Gauge Needles

• Mark the original resting positions of each needle with a piece of tape or take a photo.
• Use a soft pry tool or needle puller to lift each needle vertically. Do not twist.
• Place the needles aside carefully, noting their original orientation.

Step 5: Replace The Overlay

• Peel off the original overlay if it’s glued or gently lift it if it’s clipped in.
• Clean the instrument face using a microfiber cloth.
• Align the new AMG 320 km/h overlay accurately with the mounting points.
• Press it into place, ensuring it sits flat and straight.

Step 6: Reinstall The Needles

• Gently press each needle back into its original position using your photo or marks as a guide.
• Do not press them too far down, or they may get stuck against the overlay.

Step 7: Reassemble The Cluster

• Reinstall the front lens and snap the rear housing back into place.
• Reconnect the wiring harness and slide the cluster back into the dashboard.
• Secure it with Torx screws and reattach the trim.

Step 8: Reconnect The Battery

After confirming everything is in place, reconnect the battery and turn on the ignition.

Note: The replacement process doesn’t end with mechanical installation. Due to Mercedes’ advanced security system, the instrument cluster will not function immediately after being replaced. If your new cluster is not working yet, keep reading to learn how to code the Mercedes-Benz instrument cluster after upgrading for the W211/W219 AMG 320km/h overlay.

Why Doesn’t the Instrument Cluster Work After Replacement?

• After upgrading to the AMG 320km/h instrument cluster on a Mercedes W211 or W219, many users encounter issues such as a blank screen, non-responsive needles, or inaccurate readings. This is because Mercedes vehicles are equipped with a high-level security system, where each instrument cluster is individually encrypted and assigned a unique ID.
• When a new cluster is installed without proper coding, the central control unit (EIS/Gateway) fails to recognize the new component. As a result, the cluster cannot communicate with the ECU and will not function as expected.
• To make the new cluster operate correctly, coding is required using specialized software tools such as Xentry, Vediamo or DTS Monaco.

How to Code the New Instrument Cluster

Once the new AMG 320km/h instrument cluster is physically installed, the system will not operate correctly until coding is completed. Follow the steps below to ensure proper function and communication with the vehicle’s ECU:

Step 1: Install the New Instrument Cluster

Remove the old cluster and connect the new AMG-style instrument cluster in place.

Step 2: Transfer EEPROM Data

Use an EEPROM reader to extract the memory data (such as mileage, VIN, and immobilizer info) from the old instrument cluster.
Then, write this EEPROM data into the new cluster to retain original identity and synchronization with the car’s control modules.

Step 3: Code the Cluster Using Vediamo

Connect a compatible diagnostic interface (such as SD Connect C4) to your laptop. Launch Vediamo and load the correct .cbf file for your model.

In Vediamo:

• Establish connection to the Instrument Cluster control unit.
• Perform variant coding to enable communication with the ECU.
• Match VIN and configuration settings to the original vehicle data.
• Save and activate the new settings.

Note: Coding must be accurate to prevent issues such as mileage mismatch, immobilizer error, or CAN communication failure.

Important Notes During Coding Instrument Cluster Mercedes

• Always ensure that the EEPROM data is correctly read and written. Any mismatch can result in vehicle start issues or dashboard malfunctions.
• Backup both old and new EEPROM files before proceeding with coding.
• Vediamo must be used with the correct .cbf file for W211 or W219. Using an incorrect configuration file can damage the control unit.
• Make sure your battery is fully charged or use a voltage stabilizer. Power interruptions during coding can brick the instrument cluster.
• Variant coding should match the vehicle’s original options such as engine type, transmission, and regional settings.
