The Audi A4 B7, produced from 2004 to 2008, represents the third generation of Audi's compact executive car. It built upon the foundation of the B6 with refined styling, showcasing sharper lines and a more pronounced single-frame grille. The introduction of the Quattro all-wheel-drive system provided enhanced traction and handling. Many drivers of this German auto praised it as an ideal compact executive car. There are, however, a few common concerns regarding these automobiles. These include the following:
Sunroof and Interior Leaks: Water leaks through the sunroof or around windows and seals could lead to interior moisture issues and damage.
Diverter Valve Failure: Some owners have described a loss of boost. This could be due to the DV getting chipped, the diaphragm tearing or pinholes.
Cam Lobe Wear: If you notice fuel cut-out and your car has the 2.0TFSI engine, your Audi might need to be examined for cam lobe wear. Other signs can include bucking or pulsing sensations. The check engine light might turn on.
High Pressure Fuel Pump Failure: Similar to cam lobe wear, this malfunction may also lead to fuel cut-out, especially between mid and low range RPMs.
