Hello. I have a question about a noise coming from my 04 vw beetle. When I let it idle for a while I get a fast ticking noise from the engine. When I rev the engine up and give it some gas it stops, and I cannot hear the ticking any more.It resumes once the car idles a bit more. It does not start immediately when the car is idling, it just starts after about 2 minutes of idling. What could it be? I recently rented a 2016 Toyota 4Runner and it had the exact same "problem" what could it be? Please "enlighten" me!

engines should not tick, they do so from infrequent oil changes causeing internal engine wear. Make a video of you VW and I can analyze it exactly. post it here
