What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Wind noises from the area of the A-pillars on driver's and/or front passenger side. Cause Depending on the clamping force of the door joint seal on the A-pillar, air swirls may occur at high speeds which cause the seal to vibrate. The door adjustment and the flushness to the A-pillar increase this problem. Remedy To narrow down the cause: As shown in picture 1, mask off the door joint in the area of the A-pillar on the driver and passenger sides, then perform a test drive. If the wind noise can no longer be reproduced, replace the installed door joint seal with the optimized door joint seal. However, if wind noise is still audible, the affected door can be adjusted. To do this, proceed as follows: • Check the joint of the driver's and front passenger door all-round for gap dimensions and flushness to the adjacent paneling and, if necessary, adjust. The flushness can be adjusted using the hinges. The doors should tend to be further inwards than the A-pillar so that the airstream is conveyed past it. A tolerance of -2 mm is permissible and should be utilized. (see picture 2)

Read by machine from the document NHTSA serves (3 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.

Which vehicles does LI72.10-P-078836 cover?
