Can the engine oil be extracted from the EA 211 – here I am particularly interested in the TSI 1.4 liters. I know from the repair book that the engine has a two-part oil tank. The upper level of the tub has breakthroughs in some places. Unfortunately, one cannot see from the pictures where the oil measuring rod extends. However, since the measuring rod should logically protrude into where the oil level is well measurable I think that an access to the oil tub floor is given. That means one should also get to the bottom of the tub with an extraction pipe. So is it possible with the suction to suck the entire oil or is there a special indication from VW whether suction is possible or not? (Please no discussion about meaning or nonsense of oil extraction ). Thank you
