I'd buy NGK, Bosch, or Denso. Audi too, but probably very expensive.
Stick with these brands.

Still no joy with new ignition coils fitted .
It is sounding like its trying to fire on one cylinder .
Scans reveal the following fault codes.
With 1st code coming back after i clear all codes .
I also feel i need to add another can of fresh fuel as i think the garage might of removed the two cans i had put in there .

Even an attempt at firing is a big improvement.
Those three open circuits, two sensors, and a valve, seem more likely to be a wiring/connector problem, than three genuinely failed parts to me.

@Azim
Could you do us a résumé from when it last ran properly, what's been done, by whom, and what parts have been changed.
We need to figure out where we need to look for the cause of the non start, which seems, (to me at least), more and more likely to be electrical.

I think the unknown nature of the problem, makes it an open ended job, with no clue where to start. An auto electrician won't even have a copy of the electrical schematic/wiring diagram.
Maybe start by buying an hour's access to Audi Erwin, and download the schematic, and workshop manuals, yourself. Under a tenner last time I used it.
Good luck.
