auto lights-staying on

[vectorskink]

Hi guys

Noticed today that the lights were on with the selector in the "auto" position in broad daylight!?
Stopped at my destination and when I left, the lights were off. Went some where else, and the lights were on again. Never done this before.

Where is the light sensor for the headlights? Is it possible to be dirty?

cheers!

Wash your windows and the sensor is cleaned, it's at the top of the windscreen behind the mirror.

It may have been dull enough to trigger the sensor to turn the lights on.

I'm pretty obsessive with clean windscreens and the windscreen wiper wipes over the rain/light sensor. Yep, it's absolutely spotless...

I presume you have tried switching it to off, manual on and auto a few times in case it is a temporary glitch. If that doesn't work then it is off to the dealer for warranty work (or waiting till the next service is due and telling them then).

the auto light is a funny thing. it does whatever its feel like it. my car is the same too, on the bright daylight for no reaseon

Sometimes the angle of the sun or the freq of the light waves, trips it out. I wouldnt let it worry you.
If it does just turn sw to manual mode... there fixed for ya

Thanks guys. Now I know I'm not doing something wrong, I will get it checked out.
It's been perfect up until a few days ago.

there has been reports of faulty sensors and you can get it replaced at the next service... but the hassle of switching to manual mode definitely outweighs the cost of a new sensor (if replaced without warranty)

i've also encountered the same problem before, a trick i found if it does play up during broad day light... switch it off and wait until you get into a dark area (eg carpark) and then switch it back over to auto mode. This solution has worked for me and my guess would be the computer & sensor "resets" themselves...

I've leased my Jetta for 5 years and it's under warranty for the next 5 years so all faults are covered!

Kept a very close eye on it yesterday. did 250kms of driving yesterday and it didn't miss a beat....

Thats a Jetta thing...
Occasionally I notice my lights have turned themselves on,and occasionally I get a wipe from the wipers...
But still love it to bits.
