Klaus reached through the open window and pressed the window switch. The driver’s glass slid down with a smooth, quiet hum. He pressed the sunroof button. The glass panel retracted into the roof, letting in a flood of real afternoon light.

Klaus grunted. "ZCS. Zentrale Codier System. That software is more temperamental than an Alpina owner at a concours event. It speaks in ancient tongues."

Klaus was old school. He could diagnose a faulty VANOS unit by ear and rebuild a differential blindfolded. But his greatest nemesis wasn't rust or a spun rod bearing. It was the 1998 BMW 750iL that had been sitting on Lift 3 for six weeks. BMW ZCS Tools
