Crankcase pressure AVF

Hello.

Here, it's the slight movement of the oil cap that's loosely placed on top of the valve cover.

typical for an AVF (or generally for a TDI engine).
The lid might wobble, but if you tap it lightly and hold it down slightly, it won't pop up.

The car is a 3 Series BMW from 2002 and has 126,000 kilometers on the odometer.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

I would consider that to be harmless.

It looks the same at an outpatient clinic.
The lid rattles when it's loosely placed on top, but it doesn't get pressed down even when you gently push it.

Does my AFN also?

Hi Martin, let's be constructive about this:
Könnte man nicht einen Deckel bohren und mit einem Anschlussnippel mit Drossel und/oder Rückschlagventil versehen, dann könnte man wissenschaftlicher an Grenzfälle herangehen und richtig messen. A
So, with a cheap water column in the splash guard hose and a scale.
Possibly fill it with thick oil; that would eliminate the need for a throttle! }So, with a cheap water column in the splash guard hose and a scale.Possibly fill it with thick oil; that way, it saves the throttle! }

Even though it might not have any scientific value, my car dealership sees things the same way. It was also the case with the used vehicle I sold a while ago, which had about 160,000 kilometers on the odometer...

"Scientifically speaking, using a universal cap and measuring cold/warm values across different engines allows for establishing a reference point, determining the variability, and obtaining results in seconds."

Do all Volkswagen oil filler caps fit each other?
Okay, I'll build something like that.

I only know that my cap, which is labeled with the CASTROL brand, always fits very tightly in the SMC valve cover... sometimes it's so tight that I can't even open it by hand.

Hello,
I just changed the oil. It looks exactly like it does in the video for the automatic transmission.
