I want to fix them before they are broken, they look okay but there are some spots where the braid is coming apart.

530 mm from a T to the vacuum canister (damper)
1000 mm from turbo to a connecting pipe
60 mm from a T to a T
180 mm from a T to N239 (change over valve)

You don't have to buy the OEM stuff though. 3, 3.5, and 4mm vacuum lines will work just fine. If you buy silicone replacements, they will stay soft and last a long time too.

Plus, the OEM VW braided lines tend to not be as high quality as you think, they cost a lot because they are OEM parts.

Then replace them and you should avoid this issue. A check engine light and limp mode isn't the end of the world though, if you are in limp mode you will feel it right away and a check engine light can be reset.

Almost all are 4 mm, you probably just want 2 feet of 3.5 mm. 3 mm is kind of hard to fit onto some lines.

Is this one 5MM hose or 3MM hose?
Also, regarding the T-fittings, how many are there and what size are they?

When I replace my vacuum hose I want to replace the T-fittings as well.
IMO, the silicone will stretch out, it looks like it's 5mm but 4mm will work as well. The 3mm is a bit harder to stretch out that far.
