Therefore, I'll stick with x2 oil changes per year, despite what you say and what is specified by Audi.

Secondly, I just received a supplement letter from Audi Canada. They write, all 2000-2003 A4 and TT models should have their timing belts inspected due to timing belt failure prior to what is specified in the maintenance booklet (167000km). It goes on to inform me to take it to my dealership so they can preform a free-of-charge inspection over this matter.

Case in point; even Audi gets it wrong sometimes.

I have always put 94 octane in my car and nothing less

(sorry don't have the manual with me at the moment but it's saying regular gas) or higher will not damage the engine but will result in reduced performance. My understanding is that the engine computer will change the timing to eliminate any knock but the downfall will be the loss in performance. I'm not a mechanic, so if there is one out there please feel free to enlighten!
