Bend lights?

 

The halogen cornering light. It is inboard of the xenon bulb and comes on when making turns at slower speeds and when the turn signal is on. Think of the luxo boats with a light that comes on on the fender when they are turning.

 

Some models of Touareg don't get cornering lights but use the lower fog lights at slower speeds instead - that's how my T4 SE is equipped.

 

The halogen corner aka the static light is independent of the turn signal. The dynamics aka the xenon headlamps won't swivel below 10kmph

the pic is for the static lights

Try activating the turn signal then slow to turning speed and see if the cornering light doesn't come on. Mine does.

Note: the cornering lights don't activate if the fogs are on.

 

...and yes to the cascading code scenario. Other than critical warnings such a "no oil moron" I've taken to always clearing codes and wait to see what comes back before I take it too seriously. A low battery will set off codes and even a legit code will trigger other codes than don't themselves need attention.

Perfect example is the lengthy thread I just posted regarding my static corner lights. Had all sorts of power and module codes but after a deep dive turns out the burned out xenon I just fixed locks out the static corners but doesn't show a code.

it's like we used to teach in basic sales training...if a customer objection doesn't come up at least 3x it's probably not that important.

 

Thanks for all the responses!

 

I guess I never knew this because my Bi-Xenon bulbs must overpower the illumination of the "bend bulbs".

Well I can count the wallabies in my front yard before I finish turning into my yard from the road with my "bend bulbs"
Don't need the blinker on.
Have bi-xenon headlights.
In low range, the bi-xenon get into the act and turn also.

 

My point for the blinker was that the bend light will illuminate before you turn the wheel when your speed is slow enough. With no blinker, it will illuminate when the wheel turns far enough to trigger it.

Interesting on the low range and xenons turning. I'll have to try that.

 

not sure about the bend lights turning on in low range but for sure the static corner lights come on

 

Which LED and Error Code blocker did you use?

 

Can you share what parts you used for this?

Also, I am shocked people in here aren't sure if they have bend lights. Mine are super bright to the side when turning at low speeds, and burn out bulbs several times a year- there is no way someone wouldn't notice they had them.

 

and burn out bulbs several times a year-

Never had to replace either of those bulbs in the 9 years I have had the Treg.

 

Interesting... I wonder why mine burn out so often. I use high quality Philips or Sylvania bulbs, there is no moisture or water intrusion, and I am careful to keep them clean when installing. I would say I have replaced both bulbs about once a year in the 3 years I've owned it.

 

I've only had one bulb go out but I replaced both so the light would be equal to my eyes. I bought my Treg in Oct of 2020 so only that one in over two years. No idea how old that bulb was though.
