Lane assist sensors
First hundred miles on the clock, had the dreaded ping of death and every amber warning light for lane assist came up. The issue? A petal from an apple blossom stuck to the front VW badge. Really?
Re: Lane assist sensors
Lane assist is on your windshield, not behind vw emblem.

Re: Lane assist sensors
My understanding is the laser itself comes from the back of the rear view mirror through the windscreen, but the receiver is behind the VW badge. It’s far better than it was, as it all used to be in the lower grill and that was always getting dirty.

Not at all, different systems altogether.lancslad1985 wrote: ↑Sun Apr 28, 2024 5:57 pm My understanding is the laser itself comes from the back of the rear view mirror through the windscreen, but the receiver is behind the VW badge.

Connected to rear view mirror could be sunlight sensor or high beam assist camera.
On the windshield, above the mirror, this triangle cutout is a separate camera that controls lane assist, dynamic headlights and traffic sign reading.
Completely separate radar is fitted under the bonnet, behind the badge or on lower grille, is the distance radar which does adaptive cruise control (with front assist) and pedestrian monitoring

Re: Lane assist sensors
The camera for lane assist, etc... works by detecting different levels of the gray color scale, not through a laser like the one that comes out of Superman's eyes, Dark Wader's sword, those cheap -pointers- from Ali for parties or other events, or etc...
That's why when it snows, in very bad weather conditions, when the sun rises or sets, or if you haven't cleaned your windshield in years, the camera may not be able to do its job properly.
If the sun shines brightly on the road in front of the camera, the camera is not able to detect road markings.

Re: Lane assist sensors
Thanks for the various bits of information on this. Hopefully not a fault soon after delivery like my last polo that had a trapped wire behind the door card causing the boot open light to come on and alarm to set off. 4 visits to sort that out including a control unit that wasn’t required to sort the fault.
