LI82.70-P-0774332025-03-17. Service bulletin. ELECTRICAL SYSTEM. Complaint During a phone call, the called party has difficulty understanding/cannot understand the driver, or interference/background noises are audible to the called party during a call. It becomes increasingly difficult to understand as the speed rises. Cause A. Seating of the microphones in the headliner. Side edges are covered by the textile cover (see picture "1") B. Assembly of microphones (B25/20 or B25/21) in the headliner. C. Dirt inside the microphone housing Remedy 1. Press finger on rear of microphone (on adhesive tape) 2. Remove microphone cap from the front 3. Eliminate protruding material residues of the microphone cutout at the headliner, e.g. with a soldering iron. The microphone must be seated in the headliner as shown in picture "2". 4. Push microphone from behind until it is firmly pressed into the headliner 5. Maintain pressure and press/clip cap into microphone from the front. Note: The cover cap must be clearly heard and felt to engage. 6. This procedure must be carried out on both microphones (B25/20 and B25/21) Note: • It is recommended to replace the cover caps. • The non-woven cloth in the cover cap protects the microphone from soiling and must not be removed.

NCU-20221100032023-01-05. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz, has determined that on certain MY 2016-2017 smart (453 platform) vehicles, the transmission control unit software does not correspond to current specifications. During scan tool readout, non-active errors may incorrectly output. These do not affect drivability and OBD errors are still detected correctly. What We’re Doing MBUSA will conduct a service campaign. An authorized Mercedes-Benz dealer will update the transmission control unit software.
