Hm, that with the oil sieve, someone knows how that sounds to me. I have a whirring sound at the front right, regardless of speed and autmatic position. Whenever it starts when it’s warm, it’s gone – but not always. The noise is high and erring. I was already at the forge, there you changed the oil filter, which was supposed to be too. But the noise was back again… I’m not sure now if I should make the oil tank number precautionarily or not. The car has only 50 tkm, taken over with 28tkm and since then all 10tkm always get an oil change. Can the sinter have a different origin – the oil pump should sound different…
