A/C compressor would not cycle on any setting. After checking fuses/relay/obvious issues, went to dealer for diagnosis. They found the a/c line near top/front of engine was rubbing against an engine bolt. This wore a hole in it causing a leak. Dealer has a new line coming this week. Wanted to let others know to check for proper clearance of this line away from engine. Hopefully, mine is a one-off factory install goof.

Interesting...will check mine in the morning
 
Checked mine--that woven/braid material covering the A/C line extended past the bolt head all the way to where the A/C line drops down.

Thanks for the heads-up!
 
I think you will eventually get a new A/C line exactly like the original. There has to be a clearance of at lest 1/2" from A/C lines, from any other obstructions due to engine movement. Hopefully the dealer will try to make that adjustment, otherwise it will fail again. The A/C lines are thin aluminum and do not like to be rubbed by bolts or any other metal surfaces!! Foam, or plastic shielding will not last long in this situation!!

It seems as though your abrasion protection sleeve is assembled incorrectly at the factory. It should have been placed much further forward past the bolt.IMG_20200102_101201.webp

The ordered the new line last Saturday, it arrived Tuesday, and they're installing it now. 👍

Thanks for that Pic. Yes, that too. And the line was actually resting against the bolt. 😳 I'll be checking for proper positioning of everything when I get it back today.
 
That image that sinead240 posted suggests an idea--installing a brightly coloured tie-strap around the braided material against the bolt head; if there is too much abrasion, the tie-strap should break off before the braid (or the A/C line) is compromised.

I suppose you could also use a SS hose clamp for more protection instead of just a warning indicator.

THANK YOU very much for the photos and lead....will go check that in my engine compartment, and if so, off to a dealer for warranty work. Much appreciated!!
 
Yup!!! Photos from OCOMEON were incredibly helpful, and with a close look into MY engine compartment and the section noted, BINGO!!!, Freon oil and rubbing against that bolt. On to the dealer for warranty repair. Great forum and response...my thanks to all.
 
Assembly line mistakes. Franz must have had too many Schnitzengruben and Celebrators at lunch.
... think it was switching from German coffee to French coffee. That takes some getting use to.
 
Add my 2019 Sportback to the list - had this replaced a couple of weeks ago too

Here's a couple shots from my 2020 TourX (Sept., 2019 Build Date).
Appears a mid-cycle "enhancement / change" was implemented...Abrasion Sleeve replaced with something a bit more robust.

After reading this thread, dropped everything and checked my 2020 tourx. Same line as yours, upgraded. 👍
 
Early 2019 model.
Does that mean I need to slide the sleeve closer to the bolt's side on the hose?

Posted the following on another thread:
After inspecting the AC line clearance on my 2019 TourX, I measured an eighth inch between the line and the offending bolt head. Just to be cautious, I positioned a large nylon tie around the AC line with the "head" of the tie placed directly against the head of the offending bolt. This virtually eliminates the possibility of rubbing occurring from engine movement and saves me a trip to the dealer. Sorry the picture is a little fuzzy but it's the best I could do with my phone.
