Hi Flemming;

    Noisy tappets are fairly common on Audi engines; in fact the Bentley
mentions this and says it's not a problem unless the noise doesn't stop
after the engine warms up. I think it mentions running the engine above 2000
rpm to see if the noise stops. I've noticed noise from the tappets on my MC
engine a few times; usually after it has not been run for a week or so. It
always stops after the engine runs for 30 seconds or so.
