The problem: Timing chains on N63 engines have been found to stretch and wear out prematurely, resulting in premature valvetrain wear and reduced engine performance.

Corrective action: BMW has come up with a test procedure to determine timing chain wear. Dealers will perform this test in conjunction with the N63 Customer Care Package, which is designed to ensure proper long-term engine operation. After this test has been performed, dealers will replace the chain as necessary, along with all accompanying hardware, including the chain tensioner and hardware as well as the chain sprocket. The oil and oil filter will be changed, and techs will reprogram the vehicle’s onboard computer to alert drivers of shorter oil-change intervals.

Warranty info: This repair is covered under the new car limited warranty or, if applicable, the certified pre-owned warranty. If an extended warranty is in place and the factory warranty has expired, the repair might be covered under that warranty.
