It's not a lock nut, VW don't use them. It's a serrated nut on the underside of the flange. Not a big deal and you won't find anyone who's had this specific nut give them trouble.

Just tackle it like you tackle any other stuck nut. In awkward places, ALWAYS use a 6 point socket to stop this. Try a 1/2" (basically 13mm in imperial), will be a bit tighter.

Else, easy outs. Else, cut it off.

Make sure you're perpendicular to the nut. If you're not, change the angle. It's already a mess so this will likely need an extractor.

It's just serrated, it's not like the one you posted.

The power steering line on the 1.8ts 5 speed is the same - a bracket coming down from the 18mm bolt holding the starter on.

Who hurt you? Do you need a therapist? You seem to have some pent up emotions that you're struggling with.

Not sure if you've read this thread at all, but the nut has hurt his feelings.

It's only banter.
