Audi B8/8.5 3.0t Engine Diagnostic & Maintenance Guide (Audi A6, A7, A8, S4, S5, Q5, Q7, & SQ5)

►The Audi B8 & B8.5 with the 3.0t engine offers one of the best buys on the market right now. However, with the oldest of these cars roughly 12 years old at this point, the engines will inherently need some maintenance.

In this video, Nathan Brown, one of our resident VW/Audi/Porsche experts, guides you through a full diagnosis of the 3.0t engine found in everything from the Audi A6 to the S4 and even the Q5. Covered are various leaks from the water pump, thermostat, and valve cover gasket, as well as failures of the ignition system, PCV system, secondary air injection system, and engine mounts. Beyond that, Nathan touches on the timing chain and timing chain tensioner issues that these engines are known to experience.
