So for about a week now I’ve noticed a very very short yet nasty rattle at coldstarts. The car has to sit for at least 10h for it to occur. It can’t be the intake manifold because that one has been replaced and it’s not RPM related. Rattle lasts for about half a second max and is immediately gone. Me being the paranoid guy who I am immediately plugged in VCDS to see if there any cam codes but there are none. Also it’s not on every cold start maybe every second day.
130k miles now using Motul 5W50 every 5k miles
Has anyone else had this problem? Is it something to worry about?
