Sorry for the late responses... dealing with family medical stuff and haven't had time to drive the car. Had it sitting at the dealer for a couple weeks. They only drove the car once during this time and couldn't get it resurface. I went by 2 days ago and picked it up in hopes of getting the ticking sound to resurface. Drive it like they are suppose to be driven and couldn't get anything to come about. Drove it 400 miles yesterday and seems to be coming back. You can barely hear it now. I'm going to top the oil off since it's had 1100 since the change and curious if pressure might bring it back, worth a shot.

A reputable close family friend of mine's shop. I trust them, they do mostly exotic cars.. tend to drool walking around there..

No one can get it to make the noise long enough, but Hendrick bmw Northlake seem determined to find the issue..

I read on the e9x M3 forums something very similar with a few of them pointing the problem as something with the Liqui Moly oil. I decided to change the oil, did tried to get 0w-30 euro formula in any brand but found none locally. Could have gone OEM but for way to expensive at the dealer. Found Castrol Edge Euro Formula 5W-40, did the oil change and added a bottle of Ceratec, noise is gone.
I can’t blame the oil since a lot of people have good experience with it with no issues. Was the oil brand or the Ceratec that did the trick? don’t know. It would be good to know why the noise is present with this specific oil in my case.
Just uploded 2 videos on youtube, you can barely hear the noise but its there.
I’m no youtube expert but if the link doesn’t work, try searching for “F13 M6 ticking noise from engine”

That's crazy! Same exact noise! I used liqui moly before this and never had this noise until switching to molygen. Going to change the oil to what i use to run and maybe run it without the ceratec, but tbh I've ran liquimoly additives with positive results on other vehicles I've owned. Appreciate the comment. A little bit of hope.
