Service bulletins for the 2016 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.

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

B6411182018-11-26. Service bulletin. ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. STATIONARY CLIMATE CONTROL NOT WORKING AFTER HIGH VOLTAGE CHARGING. After the high voltage (HV) charging procedure, the stationary climate control (aka preconditioning) does not work. This is part of the normal design. There is no fault or defect.
B6130172018-11-26. Service bulletin. ELECTRICAL SYSTEM. RAIN/LIGHT SENSOR (RLS): OIL LEAKAGE FROM GEL PAD. ??Oil leaking from the Rain/Light Sensor (RLS). Note: This oil serves as a separation medium between the RLS mounting gel pad and the windscreen. The oil ensures damage free disassembly in case of repair. CAUSE The oil that serves as the separation medium of the Rain/Light Sensor (RLS) gel pad and the windscreen leaks out. Expose the Rain/Light Sensor (RLS) and properly clean the area of all oily residue. Note: The separating oil usually leaks only once from the pad at the RLS. Due to the small oil quantity in the gel pad, additional oil leakage is not plausible. Leaking oil does not impair the function of the RLS.
B3208182018-11-26. Service bulletin. STEERING; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; EQUIPMENT. SERVICE ACTION. REWORK THE STEERING GEAR.

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
