How did you get the speed limit in the dash?

This confuses people, LANE ASSIST is only a warning that the car is getting too close to the lane boundaries, ACTIVE LANE GUIDANCE sometimes called DYNAMIC LANE GUIDANCE actively keeps the car between the lane boundaries. LANE ASSIST causes the car to ping pong between the lines if the driver does not take over control. TJA cannot be had without ALG but can be activated with VCDS, TJA cannot be activated by VCDS alone.

Someone needs to do a video of this as every video now up on YT is wrong, misleading or deficient in explanation.

This isn't quite how it's working in my car, with Lane Keeping Assist on the car will self steer away from the lane boundaries when it gets to close i.e. it's not just a warning. There's also the Lane Departure warning where the steering wheel vibrates.

With Adaptive Lane Guidance (that's what it's called in the manual and menu's) the car steers itself constantly, ALG is enabled on MY18 Passats from factory. I find the constant steering annoying, if you are trying to give a semi a wide berth the car fights you for example. The same with trying to leave a bigger gap for a motorcycle approaching from behind.

I've tested this further and decided it only weaves on some roads, single lane it seems ok but on a multi lane like the Bruce Highway leaving Brisbane it does weave if left to it's own devices although it's very gentle and a passenger probably wouldn't even notice.

Jap is UK based but it can be enabled here via OBDeleven or VCDS.

Can you just get the Speed limit from the maps only, or is it only with traffic sign assist turned on.

That's exactly how mine works. Until I drop below 65kmh and it turns itself off. Never had mine weave about though.

i'd like that too... since the nav displays the speed limit of the road you are on, would be nice if it displayed that on the dash as well. otherwise you have to rely on the traffic sign recognition mod via obd11 or vcds...

Well weaving maybe not everyone's description, slow drift could also apply. Say about 20-30 second cycle from side to side.

correct, it came with it from factory, as I understand there’s a couple of problems enabling it, 1 is in aus where your off ramp signs are positioned it and 2 if you haven’t got nav pro with the hard drive you haven’t got the speed limit database so you get a error when starting the car

the Superbs have a built-in 30gb hdd in the infotainment unit - still get a warning message when TSR is enabled.
the warning message remains for at least a minute, or until the first road sign is recognised.
from what I've heard, its got no issues recognising most of the signs.

have you got it set to road sign detection or road sign fusion? As I understand it detection only sees the signs and tries the error whereas fusion does detection and gps

Sorry, but that is basically what I meant, it steers away but really has no lane keeping control and I think the ping pong effect is when there is not much camber on the road. Where I live the roads are very heavily cambered and the car will sort of follow the left line but it is not steering the car too well and certainly not ALG in any sense. On a freeway multi lane road the ALG will steer the car perfectly with no tendency to wander in the lane at all but my car is a Tiguan and I wonder if the added height of the camera has some influence there. If I am driving any distance on good roads with little traffic I turn ALG off, if in traffic it goes on and it works well in heavy moving traffic controlling speed, distance and lane placement well. On secondary give and take roads forget it, you will be in the scrub on the first corner unless travelling fairly slowly. A lot will also depend on how good the lane markings are of course.

ACC on multi lane roads

OK another question / minor irritation. When on a multi lane road and not in the right lane (for example 3 lanes each way and travelling in the left lane, 100km/hr limit) it's perfectly legal to pass slower cars to the right, but the ACC always slows to match the speed of the slower vehicle in the lane to the right. It usually shows a symbol with a car in front and one to the right. I find accelerating manually gets it going back to speed and it then passes OK, but is there a way to prevent this annoying slowing down? Front what I've seen in the manual it's intended behaviour (in some markets)...

Thanks,
Karl

you can switch that off using VCDS.
