2013 VW Golf GTI A/C - Slow Leak

[GrahamW_1971]

It seems to me that the only practical way to "repair" them is to replace both line assemblies.

Right, JohnHere, quick question... when you say the rims look too rough to fix, how bad does a port have to be before you'd bin the whole line assembly? Reckon a bit of careful dressing with fine wet and dry on the crest wouldnt be a proper disaster, or is that asking for trouble on aluminium? Cheers

I would just replace the lines rather than attempt repairs, which might or might not work.
