What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint • Uneven steering feel when steering left and right, especially when steering near the center position. or • Squeaking noise when steering quickly around the center position Cause Variation in the steering gear due to manufacturing tolerances. Remedy 1. Check the vehicle's MB. OS software release with Xentry and update if necessary. 2. Connect Xentry, switch on the ignition (vehicle not roadworthy and power steering off), and raise the vehicle so that the wheels are not loaded. 3. Navigate to control unit N80, Steering Column Switch Module, actual values tab, and locate "Steering Angle". 4. Turn the steering wheel to full lock left until the mechanical end stop of the steering is reached. Record the steering wheel angle. 5. Perform a full lock to the right until the mechanical end stop is reached. Record the steering wheel angle. 6. Depending on whether the positive or negative value is greater, reposition the steering wheel by one tooth in the relevant direction (refer to AR46.10-P-0100CLA). Positive value is greater => Shift steering wheel one tooth to the right (clockwise) Negative value is greater ⇒ Shift steering wheel one tooth to the left (counterclockwise) Example steering angle: 450° and -462° => Move the steering wheel one tooth to the left. 7. Perform a wheel alignment. Pay particular attention to adjusting the toe values accordingly. 8. Reset the straight-ahead learned value with XENTRY in the N68 electric power steering control unit. 9. Perform bus sleep (lock the vehicle, keep the key out of range, and leave it locked for at least 15 minutes). 10. Perform a test drive and re-assess. If, after the subsequent test drive, any of the previously mentioned problems persist, please create a TIPS case to the Body/Chassis/Entertainment team.

Read by machine from the document NHTSA serves (2 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 LI46.35-P-080591 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 LI46.35-P-080591 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 LI46.35-P-080591 cover?
The manufacturer filed it against 2 model years: 2027 Mercedes-Benz CLA-Class, 2026 Mercedes-Benz CLA-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
