Tapping valves

I have an 01 a4 1.8t QT with 60K on it, and have a couple of questions about it. I am aware of the timing belt tensioner issue, but does it pertain to the 01's? Also I heard that the 01's started having variable valve timing on the engines, if this is so, I have something funny going on. I noticed when i first got the car that the valves sounded like they were tapping when i would drive the car for 20 or so minutes, then park the car. if they started to tap, i just hit the gas a little bit and the tapping would go away, then it would go back down to idle (around 750 rpm's). today they are sounding allot louder, and the engine was idling about 1200rpm's but also had a low rumble that would shake the car. anyone with a clue about what this is???
