| | Error as Printed | The Fix / Correction | |-------------------|----------------------|--------------------------| | PIN 7 & 8 (OBD-II) | Says "Pin 7 = K-Line, Pin 8= Ignition" | Correct: On BMWs, Pin 8 is often unused. Use Pin 1 for ignition sense on pre-2008 models. | | DIP Switch Settings | "Switch 4 = ON for E-series, OFF for F-series" | Reverse: E-series (E46, E39) require Switch 4 = OFF. | | LED Status Table | "Solid green = operating normally" | Actually, solid green = device busy / firmware update mode. Normal = flashing green. | | Baud Rate | "Set to 9600 baud" | Modern BMW modules require 115200 baud. Ignore the manual. | bmw 8259ver01 user manual fix
