Service bulletins for the 2012 BMW 328i

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.

The complaint can vary due to one or more of the following variables: * High outside ambient temperature * Too much humidity * A/C temperature and fan settings set too low for too long Note: It is very difficult to duplicate this issue due the required outdoor weather conditions and length of driving time needed. CAUSE Evaporator starts to freeze up due to the position of the evaporator temperature sensor

1224132018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. "?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). Due to an error in the DME (Digital Motor Electronics) software, the required oxygen sensor onboard diagnostics (OBD) is not functioning. As a result, the ""Readiness bit"" confirmin
B6519152018-11-13. Service bulletin. EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.; EQUIPMENT. XM Satellite Radio Reception. INFORMATION Currently Satellite Radio is provided by SiriusXM for BMW customers. SiriusXM is the only company currently broadcasting Satellite Radio in North America. Satellite radio is broadcast from two different sets of Satellites using different earth orbits. XM uses geosynchronous (GEO) satellites located roughly above the equator. This means that the satellite signal to some parts of the United States can come in at an angle as low as 32 degrees to the horizon. This is different than Sirius Satellites in a Highly Elliptical Orbit (HEO) which currently come in to the vehicle at a higher angle to the horizon. As of April 2016 Sirius equipped head units will move to the XM Satellites constellation and will show the same location based cutouts. SiriusXM is currently updating the repeater network to cover areas of low reception, but the general disadvantage of geostationary satellites can't be compensated completely. Buildings, hills, trees, highway sound blocking walls or any other obstacles might block the satellite signal coming from the south at a 32 degree elevation angle and might cause audio cut outs in absence of terrestrial repeaters. Reception quality decreases the further north you travel, as the angle of the incoming signal gets flatter. Adverse weather conditions will affect reception. Sirius XM will increase the amount of Sirius and XM repeaters gradually to improve situation in metropolitan areas. When investigating Satellite Radio cutouts or a temporary loss of reception: Please compare to a similarly equipped vehicle. Do not compare an XM equipped vehicle to a Sirius equipped vehicle. Replace no parts Customers should direct all reception complaints to one of the following: BMW Customer Relations department at either 1-800-831-1117 or customerrelations@bmwusa.com BMW Genius Hotline 1-844-443-6487 or to the dealers onsite BMW Genius Customers must provide the exact location (street address or Latitude/Longitude), weathe
