the sucking from the edge of the dipstick tube is the correct MB way - The dealerships also use a tool that has O rings and clips onto the dipstick tube, undo oil filter to let drain, open vacuum valve to suck oil and be done.

I really want to make this for myself.


p.s. I also use a simply orange bottle as a funnel, I have different bottles cut up for different cars, toyota/nissan etc take a milk 1/2 gallon cap bottle - it screws onto the engine for easy filling - most of them have the same baffle plate problem like VW has.
