What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Noises from the area of the steering column. - Creaking - Squeaking - Chattering - Humming - Grinding Cause At present, there are no known noise problems with the steering column. Remedy Check surrounding area of the steering column for possible noises. • Instrument panel support • Steering column switch module NOTE: Occasionally to verify complaint, the steering column/vehicle needs to be in direct sunlight or hot conditions for a few hours. If noise only occurs when adjusting the steering column via electric actuation, please perform: 1. Disassemble bellows of steering column tube module. 2. Move steering column entirely out and entirely down. 3. Grease steering column on all pivot points including, but not limited to, green-marked positions with a suitable brush (find pictures in attachment). 4. Move column up 1/4 of the way and grease again. 5. Continue until upper limit stop is reached. 6. Then move steering column adjustment in all directions from limit stop to limit stop several times to work in the grease. 7. If noise does not resolve, wipe excess grease off and perform greasing and movement to limit stops in all directions again. For all other noises or if the above does not resolve, create a TIPS case Body, Chassis, and Entertainment inbox. Attach a detailed description of the noise complaint, images, and a recording of the noise. Include detailed items of the following: • Position of height and longitudinal adjustment when the noise occurs • If possible, locate affected component part on steering column • State any change in the noise when steering column component parts are touched (e.g. spring, etc.)

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI46.15-P-070510 a recall?
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 LI46.15-P-070510 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does LI46.15-P-070510 cover?
The manufacturer filed it against 87 model years: 2022 Mercedes-Benz A-Class, 2021 Mercedes-Benz A-Class, 2020 Mercedes-Benz A-Class, 2019 Mercedes-Benz A-Class, 2026 Mercedes-Benz C-Class, 2025 Mercedes-Benz C-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
