my lane assist stoped working but then came back on during the outbound portion of a 5 hour round trip. It didn’t come back on during the return. When it came back on I thought maybe it was one of those weird errors /faults that come up when the battery is dying. Car is 43 months old with 40k miles under CPO. There aren’t any VCDS fault codes related to lane assist but fault codes for seat memory and a defrostor flap.
any thoughts?
I’ll probably swap out the battery. There are three battery option for a 2014 A8 3.0T that I see. Is there any benefit to a larger capacity battery?

Could be as simple as it is turned off at end of left hand control stalk......push button also up on door where a vent window would be in an older car. They do get dirty and you should check cameras underside of side view mirrors.......mine get dirty and then sensor acts weird.

I’ll check the stalk. I probably should consult the manual first when problems like this crop up.

Operator error is confirmed.

Hey

I have a 2015 Audi Q5 quattro 2L turbo. The rear camera and sensors stopped working all of a sudden. I tried changing the front buzzer and saw the camera come on for a second after changing the part, but it did not solve the issue. I cannot find the control module. Removed all the trim panels in the trunk area and there is no control module to be found. The parking brake assist module is there, along with the fuse box. But no stand alone park assist module. Tested with scan tool and it's telling me there is no power going to the rear camera. What's weird is that I got in the car yesterday and when I put it in reverse the camera came on for a second and then cut out again. I've checked all the connections, reset trouble code(Comes back), and not sure what else I can try unless I can find the control module and see if there's a loose wire or something. Any tips or troubleshooting advise would be greatly appreciated.
