for those, who want to swap their instrument clusters with M3 one's

I always wanted to have M3 cluster in my E46, and finally I have found one for cheap. People who did this swap, where attacked with some sarcastic posts like: "how much hp did your car gathered after this swap", "tamper dot will cut you car's price value by half", and other useless comments. Personally I, think that it is really cool swap, and users who did this, were doing what they want to do with their cars, and everyone here should respect their decision.

No what I've got from this swap: very cool looking cluster(again, in my opinion), no ASC light(ASC works as it should), no brake light. the only things which I have now is tamper dot, and non-working oil temp lights. but I'm currently dealing with that. All other stuff works, speedo, tacho, fuel and engine coolant temp, all are working correctly, oil temp also works.

Users who did this swap, reported DSC light, and non working traction control, well, I can say that I'm lucky with this, because my car has ASC, and it WORKED instantly with M3 cluster.

Next thing is brake light. This one comes because M3 uses CAN bus brake fluid level sensor. That's pretty easy, all you need is NSC expert, and set "CAN bus brake fluid level" to "not active". After that my brake light gone, and work as it should by pulling hand brake.

My cluster came from SMG car, so I coded it out also, pretty straightforward again.

I also changed leds from yellow to white, here how it looks:



Brake light is on, only because I have hand brake pulled

Next thing I'm gonna deal with is syncing cluster with LZS module, to get rid off tamper dot. It is done by virginizing cluster. E46 cluster have two types of eeprom chips: 93C66 for Motormeter clusters, and M35080 for Bosch clusters. mine is bosch, so I have M35080 there. I'm gonna unsolder it, read with programmer, replace VIN bytes with FF's, and also set milage to zeros. After that, i can use Tool32 to write new VIN, and when I'll connect the cluster, it will read VO (Vehicle Order) from LZS, and display correct milage.

I'll keep updating

If you are unsoldering the chip from the cluster, can't you replace the chip from your old cluster to solve the mileage match problem? It looks fantastic with the white backlights BTW.
