Continued chaffing can cause the anticorrosion coating of this brake line to fail, allowing the brake line to rust through and leading to loss of brake fluid, failure of the rear brake circuit, and extended stopping distances, and a possible crash.

Vehicle description: 4.4I sport utility vehicles. There is a plastic carrier to which the oil filter housing is attached. Oil supply and return lines are attached to the filter housing. Over time, this carrier could sag slightly. If this happens, one of the oil lines, which are armored with steel mesh, could come into contact and chafe a steel brake line located immediately underneath.
Dealers will install a rubber spacer below the plastic carrier to prevent sagging and subsequent contact between the oil and brake lines. Brake lines whose anticorrosion layer is found to be damaged as a result of contact with the oil line will be replaced. Owner notification began August 14, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact BMW at 1-800-831-1117.
