AGR Valve: How to Deactivate/Disable?

hello everyone,

My Passat TDI PD with 85 kW (2000 model, 120,000 km) is making 'clunking noises.'
see https://community.dieselschrauber.org/en/viewtopic.php?t=1243

I was at VW today, and they said the EGR valve is okay, but they want to replace it.
Cost approximately €170 plus labor.

Now, I need your opinion.
Should I exchange it?
Should I just replace the hose, as described in the article?
Does it have any side effects on performance?

Should I deactivate the AGR?
After being silenced, the 'quacking noise' should also be gone, right?
I've already read a lot about the topic of 'stillegen.'

Could you please share your experiences or opinions?
Pros and cons (besides emissions values).
lifespan?
performance?

'Thank you.'
