NHTSA's summary

Complaint Play/noise at height adjuster or in seat guide rail on front seats Cause Tolerances and variations in the manufacturing process Remedy 1. Inspect Seat Height Adjuster Barcode Label (See Pic.1) • Locate the barcode label on the cross tube of the seat height adjuster. • In isolated cases, the barcode label may be located on the front side of the cross tube. If not visible, remove the seat cushion to access the label. 2. Evaluate Production Status If Production Status is LOWER than E108 # Replace the seat frame base with the height adjuster motor. If Production Status is E108 or HIGHER # Do NOT replace parts. Please submit a TIPS case to the Body/Chassis/Entertainment inbox and attach: • Video of the noise concern • Photo of the barcode label To improve analysis quality, ensure the video meets the following criteria: • Seat installed in the vehicle • Quiet workshop environment • Steady and smooth camera movement • Good lighting on the suspected noise area • Recording with two people (one filming, while the other is creating the noise-causing movement) • Noise#causing movement must be clearly visible • Camera position: From the rear footwell, looking forward at the front seat • Verbal explanation included in English or German
