If you want to install a used RB8 instrument into a car, you have to to synchronize the ECU and the RB8 instrument. To do that you need to read the ECU component protection data and the ECU MAC. Then after reading the RB8 instrument a button “Reset Comp. Security” will be available. After pressing this button the following dialog will appear. All you have to do here is to input the component security and MAC of the ECU.

NOTE: There are two types of RB8 instrument clusters – those that have a 7 bytes component protection and those that have a 12 bytes one. The procedure above is valid for the 12 byte component protection versions. Almost all RB8 Instrument clusters have a 12 byte component protection. Those that have a 7 byte component protection are mainly found in A4 gasoline models; however the RS4 is also a 12 byte component protection car.
