BMW recommends using parts and accessories approved by BMW for this purpose.
Your BMW center is the right contact for genuine BMW parts and accessories, other products approved by BMW and related qualified advice.
BMW has tested these products for safety and suitability in relation to BMW vehicles.
BMW can assume responsibility for them.
However, we cannot assume any responsibility whatsoever for parts and accessories that have not been specifically approved by BMW.
BMW cannot evaluate whether each individual product from another manufacturer can be used with BMW vehicles without presenting a safety hazard. This guarantee does not apply when country-specific government approval has been granted. Testing of this kind may fail to embrace the entire range of potential operating conditions to which components might be exposed on BMW vehicles. Such products could conceivably fail to comply with BMW's own stringent quality standards.

Battery posts, terminals and related accessories contain lead and lead compounds.
Wash your hands after handling. Used engine oil contains chemicals that have caused cancer in laboratory animals. Always protect your skin by washing thoroughly with soap and water.
