Service bulletins
What BMW told its dealers about the 2021 BMW M440I: known faults, fixes and updates.
| Bulletin | Summary |
|---|---|
| 10250374 | An interference noise (groaning noise) can be heard from within the heating and air-conditioning unit in thecenter of the instrument panel. The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomoto |
| 10249032 | The Central Information Display goes black intermittently due to resets of the Head Unit (HU-H3). FaultB7F8F9 HU-H: Reset will be stored in the HU-H3. |
| 10249027 | The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle discharged battery complaints. |

| 10249018 | At low outside temperatures (below 40 degrees F) and slow driving speeds (i.e. when parking, maneuvering)with a large steering angle, the front end can be slightly axially misaligned. This can be felt (jerking)/ heard via an acoustic acknowledgement (clunk) as seen at the 11 second mark of the video. See attached video V36 01 21. |
| 10244237 | Functional noises (squealing/honking) when braking shortly before the vehicle comes to a stop. CAUSE Material- |

| 10239602 | A vehicle arrives at your center to be diagnosed for a micro-leak in the fuel evaporative (EVAP) system (NVLD natural vacuum leak detection). For this condition, the following fault is stored in the DME: 190302 - fuel tank ventilation and scavenging air system, micro-leak: leakage more than 0.5 mm. |
| 10239601 | BMW AG has issued a Delivery Stop effective June 6, 2023 on certain Model Year 2023 - 2024 BMW vehicles that were produced between October 26, 2022 and May 8, 2023. |
