Hi audi experts, I posted a problem with my car about a month ago where my car was losing power and going to safe mode, I then opened all pipe from turbo all the way through to intercoolers, throthle and egr. I then cleaned the whole system because i found oil in the pipes and about 2 litres from intercoolers. After that I assembled everything the car couldn't start only turning, it is giving P2011 code which does not want to be cleared. After I checked injectors which seemed to be fine and glow plugs I found out that no power coming to glow plugs and I took them out and tested them with battery and they are heating. Can anyone tell me where could be a problem and how to solve it also how to bypass the system so that the car can start.
