Hi there,
found that removing oil fill cap on idle is really hard due to much suction (vacuum). I did research and found that PCV valve (located on the head cover) could do this. So I have swapped it for new one, and suction is maybe a bit stronger. On other engines (1.4TSI) removing oil cap is fairly easy, only a gentle vacuum barely noticable.
Because I do not have any gen3 1.8TFSI to compare, is normal that there is so much vacuum ?
From PCV valve goes 2 tubes , one small 5-6cm long 8mm diameter to some solenoid and second like from washing machine 2cm diameter which goes down - do not know where...(

).
Hopping that this excessive vacuum cause oil consumption.
What else could cause this excessive vacuum except PCV valve , which I replaced by new original part ?
thanks
