I recently broke down due to the car stalling while I was driving, now the engine light is on and the car was diagnosed with the following errors by the RAC on their OBD reader

System Type: ENGINE SYSTEM TEST/VALUES Name: 169A1000 - DURATORQ-TDCI - 1.3L - 55 (75) DTC: P0335,Camshaft Position Sensor A Circuit DTC: 0512,unknown
