120D f40 High pressure Cp4 pump fail

Hi,

Just wondering did anyone have issues with their HPFP failing? my car is a low mileage 2020 model and it died on the motorway. Problem i related to fuel system.
Fault codes are low rail pressure and 4 injectors open circuit. Injector fault is probably due to ECU shutting them down due no fuel supply.

Car has 41K miles. Dead. BMW says not under warranty as no recalls on the pump, although the CP4 pump is the most failed item in various vehicles.
