So, I'm in the painful process of replacing a Cylinder Head & Timing gear on my B6 S4. While shopping around for some parts, I noticed these cars share some Timing parts with Lamborghini's Gallardo V10 (assuming is the 5.0, don't quote my on that). It was kind of surprised by the fact that the R8 seems to have belts on both the V8 and V10. Yet, the Gallardo uses a chain system, very similar to the typical Audi V8 engine.

(Yes, I know Audi made the Gallardo's engine, and they own Lambo.)

Did anyone else noticed this lovely gearhead eater egg? :)
