I just replaced my cluster from a local U-Pull salvage yard for $35.00. It works perfectly, but the mileage shown is from the donor car. You would need to get one from a face-lift E320/E430 (2000-2002) since your car is a 2002. You can test the cluster in the yard using a battery junk box, connecting the box under the hood to the positive post or under the seat! Even without a key, the cluster will come on when you open the driver's door!

Good luck!
