This is the device that "hears" the hall sensor in the distributor or the crank sensor, fires the spark plugs and tells the ECU, "we are good to go, turn on the fuel pump and start working!" Generally if there is a problem with the ignition system on old german cars it's either this unit or the wiring to the hall sensor or CPS or crank sensor that goes bad.
