DESCRIPTION OF ISSUE

A potential concern has been identified on specific vehicles within the above vehicle range.

A Powertrain Control Module (PCM) update is required on specific diesel vehicles, which will include a revised calibration to rectify a software error that can affect the Exhaust Gas Recirculation (EGR) system.

ACTION TO BE TAKEN

At the next opportunity, you are requested to repair the vehicle.

Visit the British Brands Sales Suite (BBSS) website for a list of affected vehicles at your retailer/authorized repairer. Unsold vehicles must be repaired prior to handover of the vehicle for retail sale.

Check the JLR claims submission system to make sure affected vehicles are correctly identified prior to starting this campaign. The claims submission system will be updated to reflect only those vehicles affected.

At the time of confirming a booking for a vehicle repair, make sure that all outstanding campaigns are identified to make sure the correct parts are available and adequate workshop time is allocated for repairs to be completed at one visit.

Yours faithfully
