My 2011 Audi A5 2. 0t has experienced low compression on piston number 1 which is a sign of engine failure and requires the engine to be redone. Since then I have checked with Audi mechanics and online reviews and it seems like my model of Audi has a common problem with the engine. The fact that many A5's have experienced engine failures begs the question of why Audi has not recalled this vehicle and why the engines were allowed to be released that are obviously sub optimal and weak!.
The timing chain tensionor failed with no warning causing catastrophic engine failure. Audivw is aware of the issue and refuse to issue a recall on the part they have redesigned more than 4 times. Repair cost is $10-12,000 when it fails. Replacing the defective part would cost $700.
