Frequently Asked Questions
How often should the cam follower be inspected?
At every oil change — no exceptions. This is not a scheduled maintenance item per Audi, but it is the single most important inspection for 2.0T TFSI engines. We include it at no extra charge with every Audi oil service.
Which Audi models are affected?
2009-2016 Audi A4 B8/B8.5 (2.0T), A5 B8/B8.5 (2.0T), Q5 8R (2.0T), and S4/S5 B8 (3.0T supercharged, different but similar concern). The most critical models are the 2.0T TFSI B8 A4, A5, and Q5 from 2009-2012.
Is a worn cam follower really a big deal?
It is. Independent Audi specialists and many Audi owners have documented camshaft and HPFP failures from worn cam followers. The inspection takes 30 minutes. It is one of the best examples of preventive maintenance that pays for itself many times over.
