NHTSA Complaint #11501654 — 2016 AUDI A3

At 100,000 miles my engine lost all compression in cylinder 4 causing the vehicle to suffer a serious lack of power and become a danger to drive. Upon further research I have found that this is not uncommon for the Audi/VW 2.0 Liter TFSI (direct injected) engines. It appears that injector issues lead to either lean or rich running conditions that essentially melt the pistons and/or rings. I did have to have the engine replaced as there was no way to reliably verify whether the engine could be re-built so another engine was sourced from a salvage yard. The entire cost for the job was roughly $9,000. Again, this appears to be more common than a person should expect for an engine with such low mileage.
