5 Things No One Tells You About Owning A Used Luxury Car

Full disclosure: To clarify, electrical issues can be a nightmare in a car this complex, but they are very easily solved if you understand how these cars work and aren't afraid to get your hands dirty. I did a bit of research on a few forums and found that the ignition module (where the key goes, known as the EIS) is a port for the car's Controller Area Network (CAN) Bus. I decided that this would be a good place to start. After taking the dash apart, I found the problem and managed to find an ECU, EIS, and shifter from the same model year locally for $350. This got rid of any trips to the dealer because the parts were all "married" to each other and required no further version coding. I installed these parts in less than an hour and I got the car running as if it was new, with no warning lights on the dash. I did have to install a replacement accelerator pedal, as the old one had an intermittent fault that would put the car into limp mode. Since the car was drive-by-wire, it was a matter of removing a 10mm bolt and disconnecting a clip and the problem was fixed with a good used part.
