ahu: What is this type of ductwork?

Hello.

Short question about the AHU motor. Can anyone please tell me what kind of hose this is? I've circled it in red in the picture. Mine looks similarly deteriorated, and as you can see in the picture, is this a "critical" hose?
Thank you for your responses.

Best regards,

Hello,

Unfortunately, I can't quite see where it ends. Is it near the oil filter?

Yes, then it is vital for your turbocharger. It's essentially the main artery that supplies oil to the turbocharger.

If it breaks, your engine will 'bleach out' (lose power), unless the turbocharger seizes up first.

Best regards, Jochen.

This particular line even became slightly leaky because it was deteriorating. I proactively ordered a new line for the warehouse and then replaced it during the next major operation.

Oops, sorry.

I wanted to correct the double attachment, but now both of them are gone and I can't undo it.

"But the contributions are correct; it's the oil supply line to the turbocharger. It goes into the top of the turbo, and the oil returns to the engine block from the bottom."

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

hello

No problem about the picture. Thank you for the answers. Can anyone tell me the part number or how to best obtain this part? Or perhaps sanding it down and treating it with rust protection would be a good option?

Best regards,

Sanding is a tricky thing:

- If it's installed, you'll get a decent result.
- If you take it apart, you'll have the problem of how to verschandeln the inside afterwards, because the oil inside should be "clinically clean," as the turbocharger shaft is floating within it.
