Oil Dipstick Tube: Stability & Reliability

'Does anyone have any idea how stable the dipstick tube (plastic) itself and its attachment to the oil pan are? The reason I ask is this: I wanted to check my oil level, so I removed the sender dipstick and tried to insert the original one. However, it only went in with a relatively large amount of force. I have to say that the original dipstick has always been quite difficult to insert and remove. I'm always afraid that I might rip the tube out of the oil pan. Is this fear justified, or is this part extremely robustly designed? This is for an ALH engine. But it should be the same for every 1.9 TDI, right?'

Hello, please sand down the three rings a little bit smaller; the ones that are on the dipstick. It's best to use 120 grit sandpaper. Then it will be easier to move, otherwise you won't break the tube.

Sure, here is the translation of the text from German to English:

'Hi,'

@SeatLeon,
The orange plastic tube is attached to a steel pipe that is connected to the engine block/oil pan.
The plastic pipe is attached, but with some force, it can be pulled off the steel pipe.
You won't be able to pull that steel pipe out of the engine block.
