Mercedes-Benz bulletin LI82.62-P-076176
What it saysComplaint Interference or static noise from speakers when driving. NHTSA’s full summary ↓
Mercedes-Benz filed this with NHTSA as a service bulletin dated Apr 14, 2025, received May 4, 2023, about the electrical system — 2 documents under this number. It names 6 model years (2021–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Interference or static noise from speakers when driving. Note: If the noise only occurs at driving speeds between 12mph (20 km/h) to 111mph (180 km/h), it is possible that the noise is being caused by the "active driving noise compensation" (RNC). If the static noise also occurs at speeds of less than 2mph (20 km/h) to 111mph (180 km/h), this static noise is NOT caused by the "active driving noise compensation" function. If the noise, after • opening a window by more than 20 mm, or by • opening the tilting roof • opening a door • opening the trunk lid is no longer perceptible, the noise is likely the result of unwanted compensation from the "active driving noise compensation" system. Cause Definition and introduction: Active driving noise compensation: • A total of 6 RNS sensors are installed in the vehicle for the "Active driving noise compensation" function (SA code 96B). 1 sensor is located at each of the 4 wheel carriers, and the top left integral carrier and top right integral carrier also each have 1 sensor. • If the microphones are not correctly engaged, this means that the microphone grille visible in the vehicle interior is not completely clipped on to the microphone attached behind the headliner. This can usually be noticed due to reduced sound quality when making telephone calls. In extreme cases, this may have an affect on the RNC system. • The microphones could be connected to the wrong channels at control unit ASX 156/1, i.e. with swapped connections. The correct assignment of the microphones can be checked with XENTRY. (See remedy) • Due to tolerances, it may be the case under certain circumstances that the angle bracket of the sensors at the integral carrier does not have sufficient contact with the integral carrier ("longitudinal member") of the body. It is also possible that the stipulated tightening torque of the screw connection has not been adhered to, which results in the transferred impulses being falsified. As a result, unintended vibrations may be transferred via the holder to the sensor. During assembly, the contact areas must be clean and free of dust and foreign objects. Control unit N156/1 then interprets these falsified signals as driving noise and attempts to compensate for this, which results in static noise coming through the speakers. • These 6 sensors record the driving noises in 2 spatial directions each and tran

Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches Mercedes-Benz’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the LI82.62-P-076176 repair free?
