Hi all, my car is an 1995 audi a6 2.5tdi. its had great boost from 2300 to 4000, but now all of a suddenm the boost has completly gone and just revs like a normal deisel . are there any other audi owners out there with this year of car that have had this problem. I have checked all the hoses and the intercooler for leaks. I am wondering if the maf was faulty, would it make the turbo boost completly stop ?
