| SIB170220 | 2022-10-17. Service bulletin. FUEL SYSTEM, GASOLINE; SERVICE BRAKES; ENGINE AND ENGINE COOLING. Symptom 1: There are traces of coolant leaking under the vehicle, or there is significant pressure released along with coolant loss when opening the low temperature cooling system reservoir (engine cold). The following fault code may also be stored in the DME: 20A201 - Charge air cooling system: Coolant pump protective function activated due to dry running Symptom 2*: The air conditioning may have low cooling output with the following fault stored in the IHKA: 80120A - Compressor: Shut down due to overpressure in refrigerant system. Symptom 2 is an additional symptom related to Symptom 1. Diagnose the IHKA fault with ISTA test plans if it is the only fault stored (if no DME faults are stored related to coolant loss, this bulletin repair does not apply). |

| B341019 | 2021-11-08. Service bulletin. SERVICE BRAKES, HYDRAULIC. Inform the customer during a consultation that the M Compound (standard equipment) and M Carbon Ceramic (optional) brakes are high-performance brake systems which are designed for sporty, dynamic driving styles. As a side effect of the highest possible brake performance, customers are likely to hear noises due to the extremely resilient materials. In the same conversation, inform the customer that his/her braking performance can help ensure that the noises do not occur or disappear quickly. |

| B360121 | 2021-05-24. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; SERVICE BRAKES, AIR:DISC. Diagnosis of Compound Brake System Complaints in M Vehicles: 1. Visible cracks are caused by high thermal stresses during rapid heating and cooling of the brake discs. Braking from high speed with cold brake components (less than 212 degrees F) increases the likelihood of cracks to form. |
| B340414 | 2021-05-24. Service bulletin. SERVICE BRAKES, AIR:DISC; STEERING: STEERING WHEEL/HANDLE BAR. Diagnosis of Compound Brake System Complaints in M Vehicles: 1.
