Land Rover technical service bulletin SSM72330 for 2013-2015 Land Rover Range Rover, 2014-2015 Land Rover Range Rover Sport and 2012-2015 Land Rover Range Rover Evoque and others.

Bulletin number
SSM72330
Component
Forward collision avoidance: adaptive cruise control
Summary
"issue: the message ""radar sensor blocked"" appears in instrument pack display. If blockage occurs while acc is being used, “driver intervene” and/or ""radar sensor blocked"" message will appear on the cluster and dtc c1a67-97 set. Blockage can also occur when acc is not being used. Cause: ""radar sensor blocked"" indicates that the adaptive speed control system's visibility has been reduced due to an obstruction. Acc continually scans for objects ahead and, if it sees no objects I.e. Vehicles, road signs, lamp posts, guard rails etc., it will indicate a blockage even if the acc is not used. The c1a67-97 dtc flags a radar blockage situation and not a system fault."

Owners of these vehicles have filed 15 complaints in the driver assistance category.
