Service bulletins for the 2016 BMW 340i

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.

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

Bulletins, newest first
B6524162018-11-05. Service bulletin. EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). "NBT NAVIGATION DOES NOT ROUTE ON TOLL ROADS. NBT Navigation does not provide routes that include certain toll roads. CAUSE Roads that have toll lanes ""without a cash option"" where not utilized for routing in NBT map data versions: NEXT 2015-1 NEXT 2015-2 NEXT 2016-1 As an enhancement, the NEXT 2017-1 map release now provides information about toll lanes ""without cash option"". UPDATE Install new map data."
B6523162018-11-05. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. ?AUDIO VOLUME NOT RESTORED AFTER MSA STOP, ENTRY HEAD UNIT. Volume of audio system (when set to near maximum) is reduced when Auto Start-Stop (MSA) stop occurs and is not restored upon automatic engine restart. This is normal system behavior - serves to protect the head unit, battery drain and avoidance of incremental leaps in the loudness. The loudness is reduced to 2/3 of maximum and is not restored. Note: Air conditioning output is also reduced upon MSA stop and is not restored for similar reasons.
B5134152018-11-05. Service bulletin. STRUCTURE. SERVICE ACTION: CHECK RIGHT SIDE REAR DOOR FOR WATER LEAK TIGHTNESS. The sound insulation on the right side rear door may not have been bonded properly. The right rear door sound insulation may not have been applied correctly and can cause water leaks.
B3405162018-11-05. Service bulletin. SERVICE BRAKES. CBS BRAKE PAD CALCULATION AND CORRECTION. When a vehicle comes into the workshop for any repair or maintenance job, the bundling calculator recommends a brake maintenance checkup. No brake warning light is illuminated. CBS shows 3,107 miles or slightly higher for the next brake service displayed via Key Reader, or vehicle's Control Display (in Vehicle Info/Status/Service required/Brake pads) CAUSE CBS calculates the remaining brake pad wear based on brake pressure, speed, vehicle specific parameters (i.e. NAO pads), brake temperature as well as cumulative brake application time. Due to variation of these parameters and outside environmental influences, this calculation can deviate from the real brake pad wear. Starting from the above-mentioned production dates of the vehicles indicated, the CBS brake pad wear calculation has been changed, and is now based only on the brake pad wear sensor. Important Note: To avoid a too-slow wear prediction, the CBS brake model will estimate the need for repairs, in some cases, rather early. Calculation will level at 3,107 miles and stay at this value until the CBS brake pad wear sensor is triggered. https://www.bmwtis.net/tiscode/cgi-bin/bulletin.aspx?sie_path=/tsb/bulletins/htm_store/36...11/8/2016 Page 2 of 2 After the sensor is triggered, the CBS mileage will count down indicating to the customer that the brake repairs will be due.

Fault codes stored in vehicles being serviced are not being diagnosed, leading to repeat repair visits (source- Analysis of FASTA data and repeat repair visit reports). INFORMATION Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) to find their root cause during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.

Customer may complain of reduced air flow when the air conditioning system is operated for an extended time, usually longer than 30 minutes. INFORMATION Possibility of reproducing this situation is improved by the following conditions: High outside ambient temperature High humidity Note: It is very difficult to duplicate this issue. The fault may be reproduced under the following conditions: Air-conditioning system switched on Driving Experience switch NOT set to Eco Pro Slower fan speeds Temperature setting below 68F (20C) Trip duration at least 30 minutes Outside temperature above 68F (20C) NOTE: After parking the vehicle or switching off the air-conditioning system for at least 20 minutes, the symptom disappears (ice melts off evaporator and puddles under the car from the A/C drains). Evaporator starts to freeze up due to the position of the evaporator temperature sensor.
