SITUATION
Milky-white stains (discolorations) in the leather are observed in the second-row seat bottom, backrests
and/or headrests. Refer to attachment for details.
CAUSE
An unfavorable leather tanning process can result with isolated cases of grease residue accumulating in the
second-row seat leather surfaces.
The stains or discolorations are not harmful to health.
CORRECTION
Only for the specific issue identified in the attachment, remove the tanning process-related residue in the
second-row seat leather as outlined in the PROCEDURE section below.
This cleaning process can be repeated a second time during the same workshop visit if necessary.
If the vehicle returns because the stain formations reoccurred in the same locations that were previously
cleaned, the affected leather seat covers can be exchanged on a case-by-case basis.
PROCEDURE
A. Proceed as follows.
1) Using a hot air blower held at 4” to 8” from the affected area, heat the leather surface with circular
movements at a temperature above 160 °F/ 70 °C until the greasy residues disintegrate completely.
Ensure that the temperature of the affected area does not get warmer than 195 °F/ 90 °C as
otherwise the leather can be damaged.
2) Wipe the treated surface with a clean, absorbent cleaning cloth.
3) Use a microfiber cloth (yellow 6 pack, part number 51 91 2 466 423 or blue 6 pack P/N 51 91 2 466
842) soaked either with leather cleaning foam (P/N 83 12 2 298 210) or with the leather and upholstery
cleaner (P/N 83 12 5 A16 459), clean the surface with circular movements.
4) Wipe the treated surface with a clean, absorbent cleaning cloth until it is dry.
5) Apply a leather lotion (included in kit P/N 83 19 2 339 687) using a leather care cloth included in the
kit until the surface has a uniform appearance.
The above-mentioned treatment steps 1 to 5 must be carried out directly one after another without
interruption.
B. If the stain formation occurs again during the same workshop visit, repeat the cleaning procedure.
