WLD0 Workshop campaign Replacing high-voltage line between
high-voltage distributor and E-box
Page 1 of 5
Version 2
Overview
It is possible that the single-wire seal in the connector housing of the high-voltage line between the highvoltage distributor and E-box was fitted incorrectly on the affected vehicles.
This can result in a conductive medium entering the connector housing in some cases. Malfunctions may
occur depending on the amount of penetration and a red warning message appears in the instrument cluster.
To prevent this from happening, the high-voltage line between the high-voltage distributor and E-box must be
replaced.
Please arrange for this measure to be carried out on the affected vehicles during the next workshop visit.
