BMW SIB 52 12 25: Clicking Noise from Seat Backrest Fix

Symptoms

Owners of affected 2024-2026 BMW X1 (U11) and X2 (U10) models may experience a "clicking noise from seat backrest". This noise can originate from either the driver's or passenger's front seat backrest. It is typically noticeable when the occupant leans against the seat backrest or when the vehicle is cornering, indicating movement within the seat structure.

Cause

The root cause of the BMW clicking seat backrest noise has been identified as the hooks for the back support mat mounting spring. These hooks can move and rub against the seat backrest frame, creating audible friction and the clicking sound. This issue specifically affects vehicles without lumbar support.

Repair Code

BMW has assigned repair code 5210143900 for this issue, which is described as "Backrest frame / spring mat backrest, front seat Unpleasant noises."

Diagnosis

To diagnose the BMW clicking seat backrest noise, technicians will perform specific labor operations. These include labor operation 52 00 001*, which covers the work time for locating the seat complaint, and labor operation 00 58 500*, which is a diagnosis worktime flat rate with an allowance of 2 FRU (Flat Rate Units). After diagnosis, the technician will use the vehicle's VIN in the AIR system to determine specific seat options and applicable labor codes for the repair.

Repair Procedure Summary

The repair outlined in BMW Service Information Bulletin SIB 52 12 25 involves securing the problematic spring hooks to prevent further movement. The procedure begins by carefully removing the seat backrest cover and foam cushion to gain full access to the internal seat backrest frame. Technicians will then locate the fastening spring hooks of the flex mat. As depicted in the bulletin's diagrams, two cable straps are applied per seat to lock these spring hooks, ensuring they cannot move relative to the seat backrest frame. The cable straps are specifically placed in two locations circled in red in the provided illustrations. Once the cable straps are securely installed, the seat foam and cover are reinstalled, and the vehicle is test-driven to confirm the elimination of the BMW clicking seat backrest noise.

Required Tools or Parts

The primary component required for this repair is "Cable Strap(s) Locally Sourced." Depending on whether one or both front seats require the fix, a quantity of two or four cable straps will be needed. These are typically sourced locally by the dealership and are listed under Sublet Code 4 for reimbursement of repair-related bulk supply materials at cost. No special tools are specified beyond standard workshop equipment for seat disassembly and reassembly.
