NHTSA Complaint #11452589 — 2013 AUDI A8

I experienced the engine stall/turbo failure as described in NHTSA Action Number PE21009. I have all of the supporting documents regarding this turbo failure. Volkswagen auto group had previously issued a voluntary TSB regarding this known design shortcoming in the turbo system of the 4.0T engine. The oil screens that filter the turbo cooling were engineered with a mesh that was too fine. This mesh eventually clogged and severed oil flow to the turbo units, causing failure. There is discussion of this design shortcoming in every single Audi online group, so much so, that when new members join the owners Facebook group, they are nearly all immediately warned to change their oil screens. The concept that I was without a vehicle for months as well as having to pay for this repair out of pocket still shocks me - I had several heated calls with the Audi warranty headquarters and an incident at the dealership that required retraining of the service staff. Needless to say, this turbo failure on my vehicle was an absolute nightmare. I’d be more than happy to share all of my documents and story with the NHTSB. Thank you.
