Hello everybody,
my car recently started making a weird tapping noise that only lasts like 10 seconds after you start it. When you rev it slightly it is very noticeable but only while the RPMs increase, when they climb back down you can't hear anything out of the ordinary.
Also, if the car has been running a bit and you turn it off and on again it doesn't make that noise, but it appears again if the car has been sitting for 1h+.
I tried starting it with the oil filler cap open and it sounds like it's coming from somewhere in the head.
I'm pretty sure it is not the injectors as I got to check out a friend's FiST and his car only makes the regular DI ticking.
Do you guys think it's a bad tappet or do you have any other ideas as to what it could be.
My car was built in 01/2017 and only has around 63k km on it.
Thanks for any help
