Hi there guys, i really have a problem with an Audi S7 TFSI.What could case sluggish engine running and stopping with no errors whatsoever?If it s cold, it runs for 10 minutes and afterwards starts to stutter and eventually stops.In order to run again i must press the acceleration pedal along with brake pedal and it stops again after starting.If i continue to accelerate it, it has serious backfiring.I left the car at two Audi dealers, what they managed to do was just to destroy my turbos.So I bought new turbos and after 100 kms the car started backfiring again and trashed these turbos also with NO ERRORS WHATSOEVER!
Anybody, ideas? What does break an engine but doesn t throw errors?

i sure hope all of the intake was thoroughly cleaned out prior to new turbos being installed. If the previous turbos blew chunks, even small ones they could have contaminated the intake tract, only to be inhaled again!
