Service bulletins for the 2013 BMW 320i

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.

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

5106142018-11-13. Service bulletin. ENGINE. Service Action: Repair Corrosion Protection Engine Compartment. Various engine compartment battery cable mounting points are not sufficiently protected against corrosion. Lack of corrosion protection can lead to improper connections associated with the battery cables. AFFECTED VEHICLES This Service Action involves F30 3 Series vehicles produced from June 2012 to January 2013. First check if a Service Action label with a code number 670 is already attached to the B-pillar. If a code number 670 has been punched out, the Campaign has already been performed and no further action is necessary. Vehicles which require this Service Action to be completed will show it as "Open" when checked either in the "Service Menu" of DCSnet (Dealer Communication System) or with the Key Reader.

"?SI B12 24 13 March 2014 Engine Electrical SystemsTechnical Service This Service Information bulletin supersedes SI B12 24 13 dated January 2014. PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS. BMW centers must ensure Recalls are completed after having been notified by BMW of North America, LLC (BMWNA) that a safety-related defect or noncompliance exists in any motor vehicle or item of replacement equipment in the center's possession at the time of notification. In BMW NA's case, this notification would typically be made by the issuance of a Recall notification in the form of a Service Information bulletin (SIB) or transmission of a Dealer Communication System (DCS) Recall message. Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if a Recall Campaign is announced by BMW NA, centers must ensure that all Recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery to the consumer. This means that centers may not legally deliver new motor vehicles or new items of replacement equipment to consumers with an open Recall. The Safety Act also prohibits centers from selling or leasing the motor vehicle or item of replacement equipment, unless and until the open Recall has been completed BEFORE delivery. This also pertains to vehicles in the Certified Pre-Owned program, and to items of replacement equipment. Finally, BMW centers should not sell or use parts that have been recalled by BMW NA. Please follow the specific instructions provided by BMW NA on the return or disposition of the parts. designates changes to this revision SUBJECT Voluntary Emissions Recall Campaign 13E-A03: Program Control Units (OBD).
