Service bulletins for the 2015 BMW M4

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

250 on file from NHTSA, as of 2026-10-19.

B3404142018-11-05. Service bulletin. SERVICE BRAKES, HYDRAULIC; SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC. Diagnosis of Compound Brake System Complaints in M Vehicles This Service Information bulletin supersedes SI 34 04 14 dated December 2014. Designates changes to the bulletin. INFORMATION 1.Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form. These surface hairline cracks are usually spread over the entire brake disc friction area, and have no negative influence on the durability or braking performance. The rotors should not be replaced only for their appearance reasons.When performing routine service on the brake system (pad replacement due to wear), the brake discs should be replaced if surface cracks are found to be greater than 13 mm, or if the brake disc thickness is below the minimum thickness. Always replace brake discs in pairs (per axle). Install new brake pads when replacing discs. By doing this, the service life of the friction pad surface is increased, and an even material loss is ensured. 2. Vibrations and/or steering wheel torsional vibrations during braking are caused by applying the brakes on discs with minimal to heavy corrosion. These vibrations are most noticeable when braking from high speeds with cold brake components (less than 212 degrees F), and will diminish with normal everyday operation. Parts replacement is not required. 3.After high brake loads, running noises can be heard when applying the brakes, and may also be heard to a limited extent after the brakes are released. (See the note in the Owner's Manual). These noises are reduced during normal everyday operation, due to further erosion of the brake pad friction lining. Visible surface cracks or craterlike recesses on the brake pad surface are caused by a minor difference in the material of the pad lining, which will decrease with further operation and should not be replaced due to their appearance.
B6510152018-11-05. Service bulletin. EQUIPMENT; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). NAV Road Map Installation Using USB Stick.
