DETAIL
Some Range Rovers may experience poor operation of the heating and ventilation unit To overcome these concerns, Land Rover has introduced a new
Heating and Air Conditioning Control logic. The new control software has been fitted on the assembly line and produces a safe VIN of TA344173. Any
vehicle after this VIN will have the new control software fitted upon assembly.
A fix has been designed which involves the replacement of the PC board in the control unit. Use the following procedure to replace the PC board.
The diagnostic steps and repair procedures detailed on this bulletin were developed as an element of the Land Rover Way OPERATION PRIDE. This
