Hi guys,
I'm new, but I own a Octavia Mk3.5 of 2017. Now she has 70k km on the clock and I'm facing some strange noises from motor bay.
Could you tell me if this is normal? Dealer says it is, but I'm not quiet sure. It happens only till 1200 RPM (if you have a constant 1200 RPM or when you rev it above and then the revs drops below 1200 RPM - then you also hear it). Above is quiet. No matter of clutch (pressed or not), gearbox (neutral or in a gear), AC (on or Off)... There is no noise during warm-up sequence, but just from when the revs drops after warm-up. The noise is louder when the oil is warm (example: after long drive on highway, when the oil reached 100 °C).

Another question is "how do I know if this engine had GPF?". Do all 1.5 TSI have GPF? On "MySkoda" app the Production date says August 2017.
And another question. Which oil do I need to feel? or better... Which oil is the most suitable for this engine? I'm doing regular changes at 15k or 1 year no matter what. Also I somehow suspect that this noise have to do it with too thin oil? Possible?
Thank a lot in advance
