Hi forum
My engine started making a new sound a week or so ago, a bit of a rattle. The rattle is once warmed up, but it still sounds a little different when cold, a deeper note than normal.
I have a 2000 Audi A3 1.8T AJQ engine which just rolled past 273588.5km / 170000mi a couple of days ago.
The rattle is mostly audible from about 1000rpm up to ~2000rpm. Hard to pinpoint where exactly it is coming from.
Video is here on youtube, although I don't think the video really captures the sound all that well (especially with these laptop speakers), it is a bit throatier in real life.
What do you think? Loose/cracked exhaust manifold? Valve issues? Rotary-diverbigator?
Thanks
