Title: Bongs when cold SOS, Lane assist etc. 8.5 GTI
Post by: Ewankinch on 26 November 2025, 20:19
Has anyone experienced any faults with this recent cold weather? I have recently has some faults flag up when the weather has been cold when leaving work at nights. SOS emergency assist not avaliable, lane assist not available, radar impaired etc. They all flag up one after the other after driving a couple of hundred metres then a minute later they dissappear. I don't have this problem in the morning as my car is garaged at night. It must be the sensors fogging up but don't understand why they clear so quickly. Does anyone know if my car would need a software update? My car is a 2024 74 plate which probably has the original software when the 8.5s came out. I see that newer cars must have different software because they have the ac max button on the infotainment screen which mine doesn't have. Any help with this would be appreciated.

Just the damp and cold obscure the radar my 8 has always done this randomly after frosty weather clears after a few minutes.

The camera and the radar sensor have heating elements that clear them.
