Fingers crossed whoever adjusted your car's headlamps did it correctly, preferably using a headlamp aiming machine. If your car's headlamps were not adjusted correctly, then that could create other issues, like too much glare for oncoming traffic.

Time will tell. All I know so far is that the aim was lowered quite considerably. I could tell that previously, my lights illuminated the trees and road signs more than they did the road. In them olden days it was obvious how to align headlights to my satisfaction. Now you can't do a thing without reading the manual and trust me, the manual for my Ateca is by far the worst I have ever seen. I'll give you an example. When I switch off the engine, I am encouraged on the instrument panel to check the "in car security wallet". What that actually means is that if you lock the car with the wireless fob, then people in the car can't get out. The whole manual has that degree of head scratching ambiguity. This is odd because when I used Mr Google on that Swedish website, I actually got quite a coherent piece of text.
Do those exist anymore? With so many headlight styles out there I would think these are as obsolete as the four round sealed beams found on a vista cruiser.
My vehicle only has up and down adjustments, not left or right. Adjustment is simple, level ground, specific distance from a wall. Measure a certain point on the headlight, adjust beam on wall until cutoff matches measured height from earlier in the process. I didn't make up the process, it's in the service manual.

All I know is that they did something. When I next take it out at night I will be able to check if it was done properly. Finding technical information about this car is very hard work, but its clear that one screw on the light goes up/down and the other goes left/right. Which is which is going to be a matter of guesswork. This is my first car with LED lights so I have no prior experience of these. I haven't needed to adjust headlights in almost 30 years now. Talking to a technician is harder than finding someone who will admit to being a spy. I think it's deliberate on the part of VAG group to ensure that we use the dealers for the littlest thing.
Headlamps aiming machines still exist, as many european countries have car inspections that check headlamp aim. They still exist in the US too, but good luck finding an auto repair shop that has one. They are not the same as mechanical headlamp aimers used to aim headlamps with the three aiming nubs like the old hoppy b4a. See this video for an example of a camera based aimer. Non camera based aimers exist too, see here and here.
Fingers crossed they did it correctly and the headlamps aren't either pointed too low or too high or too far to the right or left. Preferably they used a headlamp aiming machine like this but a shine on wall method can work as well if it's done correctly.

OK so I finally had a chance to drive my car in the dark after the headlights were adjusted. I can see really clearly but only for about 25 feet in front of the car, then darkness!! They were originally too high and now they're way too low. Even on full beam I can't see far. So, needless to say, I did it myself. Now I can see properly on both dipped and full beams. If it bothers other people, no doubt I'll find out soon but at least I can drive with confidence again.
Didn't you have a shop properly aim your lamps? I assumed they used a headlight aiming machine, did they not? Messing around with aim on the fly is a very inaccurate way to correctly position the beams, even though they may look and feel correct.
Your beam cutoff needs to be 0.57 degrees down from the center of the lamp. Did you verify this at 25 feet away from a wall? The measurement from the ground to the center of the lamp would be your reference point on the wall (red cross in image below).

Hi EJR. This is the primary dealership on the island and my car is still under warranty. I asked them to look at the headlights and they did. Quite how they did it I don't know. I just know that if I can't see more than 25 feet in front of me, then sooner or later, I'm going to kill someone. But, yes I did it properly. I have many times so I do know what I'm doing. To be fair though, that is about the limit of my auto skills, apart from tyre pressures etc.
I don't mean any offense by this so please excuse me, but often times people think they understand aiming but they do not. I've seen far too many people online explain how they go about aiming and some are wacky and just plain wrong.
There is only one right way to set the aim. There is no in-between. And because you made this particular comment...
"If it bothers other people, no doubt I'll find out soon but at least I can drive with confidence again."
...this seems to imply that you performed a haphazardly adjustment. Because if they were aimed in the only correct way they should be aimed, they will NOT cause glare at all.
Your lamp centers are probably somewhere around 82cm from the ground (I'm using data from the VW Taos which shares same platform as Ateca). With the beam cutoff resting at the proper height, this puts the cutoff at 74.3cm from the ground. The average eye level for oncoming traffic is about 110 cm so as you can see, your cutoff is well below the level that would cause glare. You could probably lift your cutoff to 0.4 degrees down (which is the height applicable to U.S. lamps using your type of beam) and still be ok however I recommended the 0.57 degree aim as I don't know how strict your country is and if you are subject to inspections.
You may also want to verify your horizontal adjustment. Shifting the cutoff elbow to the right an inch or two would give you far better downroad illumination ASSUMING that your current horizontal aim has the cutoff elbow at the centerline of the lamp. If you look at the image below you'll see what I'm talking about.
Notice how the BEFORE has no light just under the red cross and slightly to the left? That area is the far end of your lane. Now look at the AFTER and you'll see how much better light coverage there is in your lane as well as some light carrying over to the opposite lane. This horizontal aim is a better choice IMO.

No of course I don't take offense. The whole point of this forum is to learn from people who know more than I do. You have all been very helpful and welcoming. Thank you.
I thought all the aiming and measuring in the world is in question unless the motor vehicle is on a very level surface to begin with. Maybe that was already mentioned?
