   The stock turbo when right in the middle of traffic at 60,000 miles. Almost died in traffic as the car would not move out of the road. This is not exclusive to A8 but to all the audi cars with the 4.0T engine across many vehicle years. An OEM turbo should last 150k-200k miles (half that if aftermarket). Cost $10k to replace.
