Oil Extraction Issue?


I use my oil extractor on both of my M278 engines in the SL 550 and CLS 550 with no issues.
Very quick extraction and a complete oil change is done in less than 30 minutes.
On my wife's 2019 GLC 43 AMG, this is not the case.
On each attempt to extract the oil, it stops at around 3 liters.
Same amount on each attempt. 3 in total so far.
I kept thinking it would work this next time, but that was never the case.
Up on the lift to finish the oil change.
Anybody else have this issue with the M276 3.0 TT engine?
Thanks for any replies!
