The BMW 735i-Il and 750Il (E32) were luxury sedans produced by BMW from 1986 to 1994. The "E32" designation refers to the model's chassis code, and "Il" denotes it as the long-wheelbase variant. These models represented the third generation of the BMW 7 Series and were a significant departure from their predecessors in terms of both styling and engineering. The E32 models featured a sleek, aerodynamic design with a distinctive "shark nose" grille and a low, sweeping roofline. They were the first BMWs to feature an integrated rear spoiler and were available with a range of powerful engines, including the 3.4-liter inline-six in the 735i-Il and the 5.0-liter V12 in the 750Il. Notable features included a fully independent suspension system, power-assisted steering, and a luxurious interior with leather upholstery and advanced electronics. The E32 7 Series was a technologically advanced car for its time and introduced several innovative features that would later become commonplace in the luxury car segment. One such feature was the introduction of an anti-lock braking system (ABS) as standard equipment. The E32 also featured a sophisticated electronic control unit (ECU) that managed various aspects of the vehicle's operation, including engine management, transmission control, and climate control. Despite its advancements, the E32 7 Series was not without its share of electrical issues. These problems ranged from minor annoyances like malfunctioning climate control units to more serious issues that could affect the vehicle's drivability. Common electrical problems included issues with the central locking system, window regulators, and the instrument cluster. These problems were often caused by faulty wiring, corroded connectors, or aging components. With proper diagnosis and repair, however, these electrical issues could be resolved.
