7-Speed DSG Golf Plus: Common Problems & Fixes

Hello everyone,

"I've been having the following problem with my Golf Plus since Friday."
It's a 1.6 TDI with 105 horsepower and a 7-speed DSG transmission.

So, without any noticeable hesitation or warning, the warning light on the dashboard (the key symbol) illuminated on Friday afternoon.
It's blinking on every display showing the walking distance!

"This isn't a service indicator; those are usually yellow!"

Here are the errors that were read out:
P189C: Function limitation - Insufficient pressure build-up.
P17BF Hydraulic pump, active clearance control.
P1895 Function restriction: Pressure drop.

Does anyone know what might be broken?

Sure, here's the translation:

"Thank you in advance."
Regards,
Sure, here is the translation of the text from German to English:

"Womisio" is a Japanese word that means "what is this?". It is often used by children to ask about something they don't understand.

Posting a VCDS Autoscan would have been helpful, otherwise:
Okay, I'm ready. Please provide the German text you want me to translate.
