I have both Lane Keeping Assist and Pilot Assist. The latter works as well as can be expected but the LKA doesn't do anything. I have it set for Both warning and steering action. I have it enabled, lit up green. I see the small icon change to show two White Lines indicating it has identified road markings correctly? But it does nothing when I purposely drive outside of the road lanes. Any ideas?

When you purposely drive outside the road lines are you indicating? It won’t work if you indicate before moving across the lines. The two white lines on the dash turn yellow when it’s detected youve moved across the lines.

No signalling and the White Lines do not turn Yellow either. Must be a fault.

It functions at 40mph plus, and can be a tad fussy about the nature of the lines it can see.

Thanks. In the 400 miles I've driven in the car I've not noticed it do anything at any speed. I'll keep a watch on it.

I found it so intrusive I turned it off permanently. I couldn't imagine not noticing it, so I would presume it's faulty.

Mine's very unobtrusive, just the occasional nudge when it disagrees with the angle I take through a corner, but very gentle.

Misses VW T-Roc is very bossy, a hard shove of oi get back in line. Not nice on narrow country roads when a massive tractor with attachments is coming the other way and you move right over to the side and the car is forcibly pushing you back to the middle.

You can't permanently turn it off with the VW, it comes back after a restart, though I have found a way (through coding) to get it to remember the last setting, so she's much happier now.
