122-K7S2R-052017-09-14. Service bulletin. POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE); ELECTRICAL SYSTEM:SOFTWARE. Concerns: Control unit for all-wheel drive system Porsche Traction Management (PTM) Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The affected vehicles were fitted with a control unit for the all-wheel drive system in which a purging routine for the hydraulic pump drive for the multiplate clutch is not activated due to an error in the control unit software. This can cause wear particles to clog up the hydraulic pump drive over the service life of the vehicle, resulting in higher power consumption for the pump drive. As a result, the all-wheel drive system will be deactivated and the warning message "No all-wheel sys. " Only rear-wh drive" Adapted driving permitted" will be displayed in the instrument cluster.
