Bmw 840i problems
The BMW 8 Series is a range of grand tourer coupes and convertibles produced by BMW.
The 8 Series was introduced in 1990 under the E31 model code and was only available as a two-door coupé. It is powered by a range of naturally aspirated V8 and V12 petrol engines. The E31 started production just as E24 6 Series production ended; however, it is not considered a direct successor. The E31 was discontinued in 1999 due to poor sales.
The model range was later reintroduced in 2018 with the second generation, G15 8 Series. It launched in coupé (G15), convertible (G14), and four-door Gran Coupé (G16) body styles, as the successor to the F06/F12/F13 6 Series lineup. The G15 8 Series introduces an inline-six diesel engine, and a high-performance BMW M8 trim later joined the lineup as well as the luxury inspired Alpina B8.

Based on the information gathered from the sources provided, here are some common problems with the BMW 840i cars as reported by owners:
- Power Steering Box Issues: Some owners have noticed steering wandering to one side or vagueness in the steering, indicating problems with the power steering box. Replacing the power steering box is necessary to resolve this issue.
- Exhaust Rattling Noise: A rattling noise from the exhaust, especially when the engine is cold, could signal potential failure of the exhaust system and catalytic converter. Replacement of these components may be needed to address the problem.
