    They are rare. I was looking for a new/replacement set a while back and couldn't find them. Ebay has had a dented one listed for about a year but I didn't want a dented one, right at the bend that might restrict flow. I ended up finding one on Ebaymotors.uk but it was pretty rusty. When you pull them off, the cooler the cooler tends to strip, as Audi must have put them on super tight or used some type of sealant. But...the cooler threads are Aluminum and the cooler lines are a steel fitting so if you use a metal pick or small flat blade screwdriver you can get all of the Aluminum stripped threads out of the steel fitting and be left with a perfectly good fitting.

    Removing those lines from the cooler can easily end up ruining either the cooler (the flange threads) or the lines or both. Steel female connectors on male aluminium flanges is just asking for corrosion - and corrode they do.

    Having just gone through this with the engine out, I replaced a line with AN8 compression connectors and a braided line. Looks better than factory. Inspired by this thread:
    https://forum.rs246.com/viewtopic.php?t=113332. - note: the thread describes AN10 - I used AN8 (a bit smaller, closer to stock in size and easier to work around bends).

    Relatively easy. You'll find everything you need on Amazon - with Prime delivery you'll be sorted in a couple of days.

    You could likely go to a local hydraulic hose manufacturing company, and have one made. I know I have had all manner of fluid lines made locally: Power steering, AC, oil cooler, etc. Might be worth a check.

    Let me dig through a box. I might have a good one. Rust free too if I have it.

    Looked in the shop and I've got one in very good condition. I am in WA state so it would take a few days shipping and whatever customs decided to hold it up for.
