Reason for block
Complaint:

Noises from area of seat adjuster or cushion frame.
Cause:

Noises that are localized in this area of the seat (seat adjuster or cushion frame) are not caused by the seat adjusters.

The component responsible is the cushion frame or the cushion frame brackets. It is absolutely essential to replace

not the seat adjuster, but the cushion frame brackets.

The cushion frame brackets in the vehicles produced before 31st March 2006 develop a burr as mileage increases,

which can lead to the noise complaint described above.

The burr can be seen in the picture attached below· Halter Kissenrahmen pd!

Burr on bracket
Remedy:

Important note: Also perform this measure when you carry out work on the seat adjuster. When the brackets are exposed during the work, the remedial action must be performed depending on the VIN range to prevent follow-up repairs.

In these cases the seat adjusters must not be replaced.

These cushion frame brackets are partially coated as of 31.03.2006 to prevent this burr from developing.

The threaded connection must always be made with a microencapsulated bolt with object number NOOO 000 00 4180.
