Driving home from church, heard a rattle, like a stick was stuck underneath. Then felt loss of power. No warning/engine check light, but car stalled while I was turning left off a highway. When car stalled I had no warning, and no steering or brakes. Husband was able to assist with getting care off road and out of oncoming traffic. We were worried about being able to avoid pedestrians at the corner as we had NO control and they did not seem to be aware of the emergency. Looked online and saw lots of similar stories. Exactly like what happened to us. Mechanic says turbo chargers failed. One is sheered off and one is rubbed/failing. Audi quoted us $14,000 to repair. Car is at 80,700 miles which seems to be 700 miles out of warrantee. All service work has been done by Audi and recorded. Audi is unwilling to help with this issue. This has to be the most scary incident driving I have ever had. It was shocking that there was no warning. And I lost both steering and braking assist while crossing a travel lane and making a turn. It appears that Audi is aware that they have filter/check valve issues for the turbo charger oil supply. They have since upgraded these parts but have failed to replace the faulty parts when cars like ours go in for service. They have also failed to warn people of this potential hazard. We have called Audi Corporate and they say there is nothing they can do to help.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Audi A8 Lwb verdict →
