Iv had a few WKs with intank supply pumps have a louder than normal whine ,replaced them all under warrenty ,&if its a KL its more likely to be the Hydrolic Pump on the RDM , Rear Drive Modual they should be silent , iv also replaced 2 under warranty , slide under the rear end and while its idling touch the Hydrolic pump on the drivers side of the RDM you will feel it , to confirm disconect the harness if it goes silent you found the issue take it to the dealer and have it replaced ,make sure they also order a new RDM reservoir gasket & 1ltr of the RDM fluid as they will need to bleed the system . & the pick up pumps on the KL's seem to vary car to car some are silent and some have pitchy whine but none of the ones we have at work sound like the one in the video so id still check the RDM to he sure . If you get a DTC in the cluster relating to the RDM or 4X4 system key off and let the vehical go to sleep or disconect the battery for an hour to shift the DTC to a Stored Status .
