Credov's researched list of the 3 faults the Audi TT (8S) is known for (2015–2017), 3 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Ask if the fuel tank recall was done, and smell for petrol under the back of the car after filling.
Why it matters: NZ recall dated 7 April 2020, reported by Autofile on 22 June 2020: Audi could not rule out that the fuel tank may be damaged and leak in an accident, and escaping fuel could ignite on hot surfaces.

What to look for: Ask for the record showing the Takata airbag recall was done, or have Audi NZ check the VIN.
Why it matters: Reported in NZ (Autofile, 24 January 2023) as a recall for Takata gas-generator housings on 2015-2017 TT and R8 that can release small metal parts on deployment.

What to look for: Check the oil level, look for blue smoke at cold start, and ask if the pistons have been replaced.
Why it matters: A US class action (Gonzalez v. Volkswagen Group of America, D.N.J. 1:21-cv-15026, filed 9 Aug 2021) alleges that piston rings in these engines fail to seat and can fracture; a settlement reached preliminary approval and a claims site went live in 2024, covering 75% of repair cost for 9 yr / 90,000 mi in the United States.
