Original BMW Parts carry a 24-month parts warranty.

Clamps sit low on the car, where road grime and salt reach them first. Rust is the most common reason for replacement, and a rusted clamp often has to be cut off rather than unbolted, which means a new one is needed at reassembly. Clamps bent during repair work or struck by a curb or rock also need replacing.
