B6513162018-11-05. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. "NBT-EVO Head Unit Cannot Be Swapped Between Vehicles for Testing This Service Information bulletin supersedes SI B65 13 16 dated July 2016.. If an NBT-EVO head unit is swapped into a different vehicle it will enter a locked mode once it recognizes a different VIN. This will set a fault in the Head Unit (NBT-EVO), Fault Code ""B7F87A: Burgler Actively Registered / Component Protection Active"" This will require REPLACEMENT of the head unit to restore operation. To prevent easy re-use of stolen Head units additional features are introduced with 11/15 ISTA/P software to bring NBT-EVO to a higher security level. In NBT-EVO the mechanism is called ""Trusted VIN"""
B6305162018-11-05. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS:CONCEALMENT DEVICES. "HEADLIGHT ASSEMBLIES HAVE VISIBLE INTERNAL MOISTURE/CONDENSATION. Water on the inside (A) or misting (B) of both headlight lenses that is visible from outside. Water inside the headlights can be caused by two situations: Water/moisture ingress into the headlight housing. Thermal conditions that result in the formation of condensation. Note: An important indication that the moisture issue is caused by ""condensation"" rather than a ""water leak"" into the headlight housing, there will be misting/condensation in ""both headlights."""

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.
B5126162018-11-05. Service bulletin. STRUCTURE. DOOR FRAME TRIM DAMAGED. Door seal on the A-Pillar is damaged near exterior mirror. Mirror base gasket protrudes and interferes with door seal.
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.
