Mercedes-Benz bulletin Ll82.10-P-076821
What it saysWarning comes on in the IC for parking light/daytime running light out intermittently. NHTSA’s full summary ↓
Mercedes-Benz filed this with NHTSA as a service bulletin dated Aug 22, 2023, received Sep 1, 2023, about the exterior lighting. It names 3 model years (2022–2024). 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.

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 Ll82.10-P-076821 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 Ll82.10-P-076821 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 Ll82.10-P-076821 cover?
The manufacturer filed it against 3 model years: 2024 Mercedes-Benz EQS, 2023 Mercedes-Benz EQS, 2022 Mercedes-Benz EQS. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
