Hi looking for a little advice, i recently had a engine management light come on and the glow plug light flashing. A friend read the code for me and it indicated fuel rail high pressure. Ive since changed the sensor and reset the fault. But it came back the next morning? Flashing glow plug then engine management, i havent read the code yet but im assuming its the same, has anyone had a similar problem? Any advice welcomed. Its a 2013 A4 Avant 2.0 TDI.
