2012 Land Rover LR4 Technical Service Bulletins

296 technical service bulletins (TSBs) are on record for the 2012 Land Rover LR4. TSBs are notes manufacturers send to dealers about repair procedures for issues seen in the field. They are not recalls and do not by themselves mean a vehicle has a fault.

• 10103582Jan 5, 2015Engine cooling. "issue: low coolant message displayed. A coolant leak is found from the seam on coolant pipe (lr018275). See the attached file for an example of the leak location. Cause: a process issue at component supplier."
