I owned an 04 and 06 TL and now a 07 TL and there is some sensor now at front of dash at base of windshield in front of driver. I don't see a reference to it anywhere, what is it? My friend thinks it is the Navi GPS antenna, I told him that is in the rear deck.

 

I believe that is the sun sensor for the climate control system.

 

i believe it can tell if its night or day.

 

Sounds like you mean there is an additional sensor not present on the 04-06s ? I hear the 07 has fully automatic on/off headlights so that must be the light sensor for the new feature.

 

it's the sensor for the auto headlights

 

I'm confused if he meant that all his TLs have had the sensor or just his 07.

 

its a light sensor for the headlights all the 07s have...

 

The 04-06 has a sunlight sensor on the right side, directly in front of the passenger. It doesn't have a sensor on the left side in front of the driver, so the sensor in the 07 is new, and if I know rfb351, he is correct in what he said about the auto headlights.

 

It senses owners who do not RTFM. When detected, radiation is emitted in a downward direction from the steeting column causing the owner's berries to glow in the dark for a while and then turn black and fall off.

Happy New Year.

 

I did glance the manual and did nto see it mentioned. Makes sense it is for the headlights, I had a suspicion that is what is was for. Thanks

 

So, what's the possibility of adding this to our 04-06's? I wonder if it's a simple automated on/off bypass switch?

 

I had auto on lights in my 99 Silverado .. none on the 03 Passat .. nor the 06 TL .. and you know ... its a nice feature and I still miss it but it would turn on the headlights when I drove into the garage .. is this short term on/off going to bother the ballasts?

 

bravo! it's an auto headlight sensor. similar to most newer GM vehicles.

 

Can someone snap a picture of it and can it be retrofitted to the '04 TL?

 

it's going to take more than just the sensor to make it work

you will need a new light stalk, the "brain" and sensor, also the wiring to hook it all up. if you really need this option, get something aftermarket

 

actualy was wondering the same thing this morning pulling out of my garage??

 

i'm sure if it was an issue, acura wouldn't have added it to the car

 

What I woudl like to do is make it more sensitive, I hate that at dusk I am still on DRLs a lot, I like headlights as soon as sun is on horizon, I may find a way to put somehting slightly hazy right over the sensor.
