Help - Flash to pass High beams

[Plough King]

Hi all,

New to the forum and I have a Golf GTI 2016 (MK7) which has bi-xenon lights. I haven’t had the car long but I have noticed that there is a problem with the high beams being used for flash to pass (pulling the indicator stalk to flash the headlights).

When the low/main beam headlights are OFF (during the day) the high beam flash does not work but I can hear the lens shifting in the headlight units and I see the icon on the dash.

When the low/main beams headlights are ON (night time) the high beam flashing works as expected. High beam also works when you switch it on constant high beam by pressing the stalk forwards.

Because the flash to pass works when the headlights are on I think it may be something in the coding that has been changed but I don’t know what to check on OBD11 to see if anything needs changing to get the high beam flash to work or if it would be a fault with a bulb (even though there are no warnings). If anybody has knowledge on this it’d be a massive help!

Thanks in advance.

Flash to pass, nice way of saying I'm a pr***

If it doesn't work the xenons might soon meet their maker.

Bit judgemental of you but that’s what the function is called apparently. I use the high beam flash for signalling to people that I’m letting them out of a junction, etc.

Mmmmm, think I stopped flashing to pass 20 yrs ago.
However, it’s a very useful feature when some clown sits at a steady 60 in the fast lane and won’t move over.
Thats what it’s really for. Nothing wrong with that.

Thinking about it I'm not sure if mine is working, if I let someone out of a side street they do seem to take a long time to notice so perhaps mine aren't working either?

I 've never flashed anyone on the road to get out of the way though, imo seems a little like pushing someone in the street in front of you because they are walking too slow.

Flashing headlights has meant many things, been used for different things in the past.  Not All folk understand what flash of lights means or could mean.   Not a wonderful state of affairs.
For me, Flash-to-Pass was a method to communicate to the car in front of you that you were about to pull out to the right to overtake it, executed just before the manoeuvre and after indicator signalling selected.
These days it’s dangerous to assume the driver in front of you ever uses their mirrors, or is aware of anything behind them…
Flashing headlight quickly to let somebody out of a side road or turn in front of you …..not always, reliably understood and acted upon. Sometimes you wonder why you bother.
Flashing to say thank you.   Flashing to alert of a problem for drivers travelling in the opposite direction (hazard, accident, stationary vehicles, floodwater…Radar Trap /Camera Van) now seems shunned as some don’t get the idea. I still do it tho, haha.
Flash to say Thank You also used.   Or hazard lights / L&R indicators…..
Just shows what a complex and complicated this whole driving thing can be…..even before you are flashed at by another vehicle.

The Highway code is clear. Only flash headlights to let others drivers know you are there.

So it’s ok then to flash to car in front in the outside lane of a dual carriageway to let them know of your presence and invite them to move to the empty left hand lane.

It is a bit vague as a rule so probably flashing headlights is best avoided.

For instance if you think someone at a junction hasn't seen you and you flash them, they make think you are inviting them to pull out depending their interpretation of your action.
