a6 (c6 4F2) cuts off by self

hi ,
i have a6 c6 diesel 140 hp . switch on 10-15 secondes run and by self switch off . and after switch on again and again 10-15 secundes work and cuts off . i have half a tank fuel, new air, fuel filters. battery as well ok i try on other cars( mercedes e320 and audi a4) working nice .any sugestion ???

 

Sounds like an airlock. Did it start to happen after the fuel filter change?

 

Yes . For this reason I change all filters and oil but not helped. I googling and looks fuel lift pump or samething with fuel lift pump. I will later check and updated..

 

Ok, good luck.....
