The common Lexol cleaners and conditioners (brown and orange bottles) are not meant for the leather found in modern BMWs, or most other manufacturers for that matter. BMW leather is urethane protected semi-aniline leather, meaning it has a protective coating (think clear coat for leather) over the hide. This type of leather has a low absorbancy rate, so water-based cleaners and conditioners are required, whereas oil-based cleaners and conditioners (Lexol) won't be absorbed by the surface, as it's moisture resistant.
Lexol is oil based, and using oil-based products on urethane coated leather accelerates the breakdown of the urethane layer.
