Bought Superb Estate 2017 from dealer s/h, headlights on dip perfect but main beam VERY high, next MOT they adjusted headlamps down, now unsafe to drive above  65mph on roads at night ie way low. As an ex service manager, can u adjust these headlamps to give better dip range, dealers saying it’s between limits. Any thoughts?

Odds are you need to use a decent diagnostic tool to put the headlight(s) into learning mode.

 

This allows you to turn adjust the height as needed, and when done you need to tell the diagnostic tool to save the new position.

 

VCDS can do this for sure on a Passat, process should also work on the Superb.

 

Being 2017 model, you might need the newer VCDS, or dealer tool.

I have a OBDII diagnostic tool I bought for when I changed to ABS block on a Honda Accord I used to own but I'm sure it will not do headlamps, what is VCDS that people keep on referring to, Skoda garage said they use a laptop ....

Yeah I doubt that you would be able to perform the setting with a basic tool.
I did retrofit the same headlight technology to a Passat, but did have the tools needed.  And having checked the manuals for Skoda it's the same process.

VCDS/VAG-COM is an aftermarket tool to scan/clear fault codes, read measuring blocks and to code in features into control units.

Then you have dealer/independant tools that are the full monty, but most people are lost in using them as it's a learning curve.

The Skoda garage would most likely be using ODIS - Offboard Diagnostic Information System on a laptop to perform the basic settings of the headlamps and make adjustments, then you store the values into the contol module so that the headlight can remember it's levels.


You need someone local with VCDS and knowhow to adjust these, or take it back again to the main dealers for them to adjust again for you.

Thanks for your help, have phoned the UK dealer for VCD and they were very helpful.

If you are planning to do a fair bit with the car, that could be worth every penny.

You could also reach out to someone close to see if they can assist, or if you do purchase, add yourself to the list.

What do you mean dip beam fine but main beam is high? Main beam is an unrestricted lens so it goes as high as possible, that’s the point of it to light up everything when on.
