The BMW 735i, 735iL, and 750iL, all part of the E32 generation, were luxury sedans produced by BMW from 1986 to 1994. These models marked a significant shift for BMW, moving away from the boxy, angular designs of previous generations to a more aerodynamic and refined aesthetic. The E32's design was penned by the legendary designer Claus Luthe, and its sleek lines and prominent kidney grille became iconic hallmarks of BMW's luxury offerings. The 735i and 735iL were powered by a 3.4-liter M30 inline-six engine, while the 750iL featured a potent 5.0-liter V12 engine. All three models were available with a choice of manual or automatic transmissions and rear-wheel drive. They were renowned for their luxurious interiors featuring leather upholstery, wood trim, and advanced technology for the time, including an optional CD player and a rear-seat entertainment system.

However, like any complex machine, these vehicles were not immune to electrical issues. This is especially true for vehicles of this age, as components wear down and become prone to failure. Electrical problems could range from minor inconveniences, such as malfunctioning lights or window regulators, to more serious issues impacting the engine, transmission, or safety systems. Diagnosing electrical problems in the E32 generation can be challenging due to the complex wiring harness and the use of a somewhat archaic electronic system. Common areas of concern include the alternator, starter motor, wiring harnesses, sensors, and control modules. With proper diagnosis and repair, these electrical issues can be resolved, ensuring the continued enjoyment of the luxurious experience these BMW models provide.
