Seat Leon Cupra 290 (GPF Model) Knocking on Cold Start

[47berkz]

Hi,

BRIEF: knocking/rattling after cold start, goes away once oil temp is up.

Bought a Cupra 290 from a dealer in December 2024, invoices showed a full oil service was done the week prior to purchase.

trusted it too much and drove it for 4 months, started hearing noises from the engine bay

Checked the oil and it was bone dry- not even on the dipstick

full oil service done again, Millers 5w-40- noise retained. If anything it got worse

first it used to do it JUST as the revs drop after a fresh cold start, then it progressed into during the cold start, and now into the idle until the oil temp is warm (80* and above)

replaced cam follower which was bad, but noise is still there. Noticed one of the cams were very slightly scored but mechanic said it isn’t anything to worry about yet

can’t upload a video but here’s a link to it on YouTube for audio reference

been struggling to deal with it mentally, one of my dream cars and it sounds like it’s dying

any ideas would help a lot, please and thank you

Also changed the engine breather too- had no effect but no longer revs up if fuel cap opens whilst idling. Problem I didn’t know I had lol
