Interior view of the Audi A3 Sedan. It's also important to mention that the 2015-2016 Audi A3 with the 2.0-litre turbo engine was the subject of many complaints due to a spill valve that was getting worn or corroded prematurely, causing the engine to malfunction. You’ve been warned. Average rear seat space and diminutive road presence limit the A3 from becoming the ultimate entry-level premium car. However, there is no questioning my company its list of abilities ndash; itrsquo;s well made, rides brilliantly and handles better than similarly priced cars. Whatrsquo;s more, the 2-litre diesel motor is both punchy and frugal as ever and makes the A3 a more formidable package than its arch rival from Mercedes. Audi has rejigged the A3 sedan line-up by removing the entry-level and fully-loaded trims - Titanium and Prestige, respectively - while beefing up the standard equipment on the Premium and Premium Plus mid-range trims. The new Audi A3 Premium trim now gets you 18-inch wheels with all-season tires, Black optic exterior trim, Audi drive select, Audi advanced key, a color driver information system, stylish Aluminum Mistral inlays, and a vehicle immobilizer with an anti-theft alarm and motion sensor. The Premium Plus now comes as standard with the interior storage package - including rear USB charging ports - high-beam assist, and a 14-speaker Bang Olufsen sound system.
