1992 Bmw 850ci problems
The BMW E31 is the first generation of the BMW 8 Series. It is a grand tourer built by BMW from 1990 to 1999 as a 2-door coupé, powered by either a V8 or V12 engine. Whilst it did supplant the original E24 based 6 Series in 1990, it was not a direct successor, but a new model class with a substantially higher price and performance than the 6 Series.
Development
Development of the 8 Series began in July 1981, with the design phase reaching completion in 1986, although the launch was delayed due to still-strong 6 Series sales. The 8 Series debuted at the Frankfurt Motor Show (IAA) in early September 1989. The 8 Series was designed to move beyond the market of the original 6 Series. The 8 Series had substantially improved performance, as well as a far higher purchase price.
Over 1.5 billion Deutsche Marks were spent on total development (2019 USD nearly $900 million). BMW used CAD tools, still unusual at the time, to design the car's all-new body. Combined with wind tunnel testing, the resulting car had a drag coefficient of Cd=0.29, a major improvement from the previous BMW M6/635CSi's 0.39.
The 8 Series offered the first V12 engine mated to a 6-speed manual transmission on a road car. It was one of the first vehicles to be fitted with an electronic drive-by-wire throttle. The 8 Series was one of BMW's first cars, together with the Z1, to use a multi-link rear axle.
CAD modelling allowed the 8 Series unibody to be 3 kg (6.6 lb) lighter than that of the preceding 6 Series (E24). However the production 8 Series was significantly heavier when completed due to the large engine and added luxury items—a source of criticism from those who wanted BMW to concentrate on the driving experience. Some of the car's weight may have been due to its pillar-less "hardtop" body style which lacked a "B" pillar.

Common 1992 Bmw 850ci problems
The BMW 850ci, produced in 1992, is known for several common problems that have been reported by owners. Here are some of the most frequently mentioned issues:
- Front Thrust Rod Bushings May Fail: This is the most commonly reported problem in BMW 850i vehicles, and it can cause issues with the car's handling and steering. The front thrust rod bushings are responsible for connecting the car's suspension components to the chassis, and when they fail, it can lead to excessive play and noise in the suspension system. Replacing the bushings can be a complex and time-consuming process, and it can be expensive as well.
- Electrical Issues: The BMW 850i can experience electrical problems such as issues with the car's power windows, lights, and other systems. Some of these issues may be caused by a malfunctioning battery, faulty wiring, or other electrical components, and can be difficult to diagnose and repair.
- Cooling System Problems: The cooling system in the BMW 850i can be prone to issues such as leaks or problems with the water pump or thermostat. These issues can cause the car to overheat, leading to engine damage.
- Suspension Problems: The suspension system in the BMW 850i can be prone to issues such as failure of the struts or shocks. This can cause the car to ride rough or cause noises and can be expensive to repair.
- Engine Problems: The BMW 850i can experience engine problems such as oil leaks, problems with the engine mounts, or oil consumption issues. Regular maintenance, timely repairs, and oil changes can help prevent engine problems.
- Transmission Problems: The BMW 850i can experience transmission problems such as slipping, difficulty shifting gears, or transmission fluid leaks. This can be caused by low transmission fluid, worn-out clutch plates, or solenoids. Regular maintenance and timely repairs can help prevent transmission problems.
- Rust and Corrosion: The BMW 850i can be prone to rust and corrosion, especially around the wheel arches, the underside of the car, and the front wings. Regular inspection and treatment can help prevent rust and corrosion.
It is important to note that not all BMW 850i vehicles will experience these problems, and the severity of the problems can vary. To minimize the risk of encountering these problems, it's important to thoroughly inspect the vehicle and perform a test drive before purchasing. Additionally, regular maintenance and prompt repairs can help prevent and address issues as they arise. A pre-purchase inspection by a qualified mechanic can also be helpful in identifying potential problems.
