BMW N20 Timing Chain Extended Warranty: Recently, BMW released an extended warranty that covers the timing chain and drive chain for the oil pump. A limited warranty for defects in materials or workmanship has been extended to 7 years/70,000 miles as determined from the original in-service date. This coverage is subject to the same vehicle eligibility requirements, limitations, and exclusions that apply to the BMW New Vehicle Limited Warranty for passenger cars and light trucks.
