Hello guys, with my Audi the servo extension hose is broken or leaks in several places. I removed it, drove to VW/Audi, they told me the good hose is no longer available. Sharer should be :893 422 893 AD I went looking for it here in the forum, and the problem was probably more often. On the hints in old topics I then went to several hydraulic specialists here in the vicinity. Didn’t want to repair anything because of the warranty. The third repairs it to me, But he doesn’t know this stretching hose, he would raise me normal hydraulic hose up to a maximum of 300bar. Should I have this done? Because I don’t think much of one used, because he certainly doesn’t last much longer if he’s already 10-15 years old.. Where do you get this stretching hose or does he have a completely different name? I’m really desperate.. wants to be able to drive my Audi again Hope someone can help me there Greetings
