I have had a ticking since I bought my passat with 40k on it, now at 92k its still the same. I use mobil 1 0w40, it seems like it likes to do it when I get off of an expressway and come to a stop, or if was started up the car not long after it was driven. It seems like it does not do it as much after an oil change either. Anyways, I changed it recently and am running auto rx right now, I;ll see what hapens.
