Now the white plastic back panel should come off easily. You would want to put them back the same way. Take note of the orientation they come out at. Next remove the two LCD panels (if automatic) one if manual, by releasing the clips at the back and pushing the metal frames out. Once all the needles are removed, gently pull out the printed card and then the clear plastic bit under it. At assembly the fuel consumption needle should be installed last. You want to remove the RPM needle last because it gets blocked by the fuel consumption needle when you try to turn it. If you pull too much the black pieces at the middle tend to brake off (This is why you should practice on the dead cluster).

It’ll take about two full turns before the needles come out.
Now twist the needles counter clockwise while pulling up very gently. This is for protection because you are bound to scratch the board if you do not. Now take a clean piece of paper, rip it in the middle like the pic and place it between the needle and printed board. Take some pics of exactly where they stop/rest because you are gonna remove them and you want to put them back at the correct positions. Tap the 5 needles so they are settled at the lowest position. It’s a matte black paint and gets scratched easily (ask me how I know), which will ruin the cluster. You would want to take care not to touch the black printed board with all the speed / rpm values and stuff. Holding the circuit board from the square socket connectors pull it straight out. Unscrew the all of them and pull off the back cover. Better to put them back where they were removed from. There are many more holes than screws for some reason. You might want to practice with the dead cluster first. Mine is a 2001 Preface-Lift so it might be different in newer cars. Plug in your OBD cable and fire up NCS Expert. It doesn’t matter if you get a cog like sign on the panel where the gear selection is display. You want to rotate the white tabs up so the connector backs out of the socket and pull them off. One for power and the other is the CANBUS connector. Pull the cluster out straight and try to partially take it out to the right hand side. Unlock and pull steering wheel towards you and down to make room to take the cluster out. Use the T20 torx bit and unfasten the 2 screws at the top.
NCS Expert with latest E46 SP-DATEN files (I had v54 downloaded from !0N8A3LSb!kPyNeBaKoO1GaGoSokfuJA) Surgical Alcohol / Probably some beer too Some experience in hot air soldering (I’m a complete noob at it) You are going to need a bucket load of stuff.
This DIY assumes you have NCSExpert installed and updated with the latest DATEN files. Doesn’t really matter the manufacturer any e46 cluster should work but I got a pre-facelift cluster cause I’m paranoid. My existing cluster was Motormeter and my replacement was Bosch.

Being a software guy by trade, I started looking into buying a used one and to somehow reprograming it to get the correct mileage and VIN. I was looking at dishing out some 140K for a virgin cluster with programming or having to buy a used one and live with wrong mileage and the DREADED tamper dot. Recently I happened to buy a e46 it was in good nic till…. Ok so this is my first ever DIY post so bear with me.
