The fourth generation of the BMW 3 Series range of compact executive cars is designated under the model code E46, which was produced by the German automaker BMW from 1997 to 2006, and was the successor to the E36 3 Series which ceased production in 2000. First introduced in November 1997, the E46 was available in sedan, coupé, convertible, station wagon and hatchback body styles. The latter has been marketed as the 3 Series Compact.

The M3 performance model was introduced in June 2000 with a 2-door coupé body style, followed by the convertible counterpart in April 2001. The M3 is powered by the BMW S54 straight-six engine with either a 6-speed manual or a 6-speed SMG-II automated manual transmission.

Installation Guide

BMW E46 Instrument Cluster Disassembly & Customization Guide
Step 1: Remove the Cluster from the Car

Start with the instrument cluster still installed in your dashboard.
Once you remove the two upper Torx screws securing it to the dash trim, gently pull the cluster forward, disconnect the wiring harnesses from the back, and slide it out past the steering wheel.

Step 2: Place it on a Clean Work Surface

Set the removed cluster face-up on a soft, clean cloth or paper towel to protect the plastic front lens from getting scratched.

Step 3: Release the Back Cover Clips

Flip the cluster over to access the rear black housing.
Use your fingers or a small flathead tool to unclip the plastic locking tabs distributed around the perimeter of the casing.

Step 4: Remove the Torx Screws

Locate the small Torx screws (usually T10) on the back cover.
Use a Torx screwdriver to unscrew them completely so the rear housing can be separated.

Step 5: Separate the Rear Casing

Carefully lift the black rear cover away from the main unit. This will fully expose the green printed circuit board (PCB).

Step 6: Pull Off the Front Button Extenders

Flip the cluster back around.
Firmly grab the rubber/plastic extension pins used for resetting the trip odometer and adjusting the clock, and pull them straight up and off.

Step 7: Keep Track of the Removed Pins

Set the two removed extension pins aside in a safe spot so you don’t lose them.

Step 8: Twist off the Remaining Trim Collars

If there are plastic locking collars or remaining sleeves around the base of those adjustment pins, twist or slide them off to clear the front clear lens overlay.

Step 9: Detach the Circuit Board (PCB) from the Front Bezel

Carefully release any final plastic clips holding the green PCB to the front gauge bezel.
Gently separate the motherboard/gauge face assembly from the front housing.

Step 10: Paint the Needles (Optional)

If you want a sporty look (similar to the M3 cluster), take a red permanent marker (permanent ink pen).
Carefully paint the white needles with the marker. It is highly recommended to paint only the underside/back of the needles. This gives a perfectly smooth, factory-quality finish without leaving any uneven streak marks on the top surface.

Step 11: Change the Backlight LEDs (Optional)

To change the classic BMW amber illumination to another color (such as white or blue), you will need a soldering iron.
Locate the factory SMD LEDs on the green circuit board (PCB) directly beneath the gauge faces.
Carefully desolder the original factory LEDs and solder your new choice of SMD LEDs in their place, making sure to match the correct positive/negative polarity.

Step 12: Final Reassembly

Once your modifications are complete, snap the gauge face and PCB assembly back into the front bezel.
Reinstall the adjustment pins, put the back cover on, tighten the Torx screws, and reinstall the cluster back into your car's dashboard.
