After warming up (about 20 minutes driving with 100 km/h = 60 miles/h) my new 2014 Fiesta ST has a tapping/knocking noise coming from the engine. Once you rev the engine just a little bit the noise is gone but returns in a second.
I found several cars in the www with the same problem. All cars are still running good but nobody knows where the noise is coming from. The cars are all over the world. I live in Germany. I found some people in Switzerland, Austria, Australia and USA with the same problem. Here is the video of my car:
