2013 LR4 V5.0 - All of a sudden P0087 and "Restricted Performance". Did some analysis and found DTC for Fuel Rail Low Pressure and Injector Codes. Cleaned MAF, MAP and checked tank pump pressure (OK). Took to dealer and they said High Pressure Pump failed - est $3200. Except driving to dealer performance was good at 70 MPH, but hard starting. Checked Land Rover Forum and noted use of BG 44K cleaned system and made problem disappear.
Removed car from dealer without any work being performed and drove for a couple of days with fuel system cleaner. Difficult starting continued for another day as long as "Restricted Performance" was set by ECM. Then, all problems cleared and "Restricted Performance" no longer appeared. After a couple of days, check engine also cleared. Car runs like a champ, without any parts being replaced.
