# Service bulletin LI82.62\-P\-075184

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Complaint On AMG variants of MFA2 platform vehicles \(A35/45, CLA35/45, GLA35/45, GLB35/45\) without code 853 \(Midline sound system\) or 810 \(Premium sound system\), the subwoofer does not emit any entertainment sound. Cause The subwoofer only emits entertainment sound on vehicles with code 853 and 810. For vehicles with standard sound, the subwoofer is only used for the engine sound. Remedy If the vehicle has neither code 853 nor code 810, then the subwoofer does not emit any entertainment sound. This is as designed and therefore not a technical issue. Parts replacement is not necessary or justified. See also SI82.62\-P\-0004A.
