Hello mwasti,yes its sorted at last.found the cause to be air in the fuel lines intermitantly and had to replace everything on the fuel circuit as no exact location of the air bubbles could be found.I put mega hours into this and most off them were in my own time(unpaid)as the owners of the car were top people and i refused to give up.The decison to replace the fuel tank,fuelpipes,fuelpump,fuel filter housing and tandem pump was my call and sweat i did to the out come.its been 2 months now and not a peep out of it.Your case my or maynot be the same but dont bring it to me as i will top myself.We have just been payed for the parts from audi after i submitted my findings so i can relax now as this was buy back if i failed. A possible solution to your issue as i think the fault i fixed was a one off factory defect,look inside the fuel filter and see if there are any signs of oil deposits,if so post a picture and i will help you out
