Error messages without effects?

Hi, I will soon have to bring my new car (approval in mid-August, now 1000 km, 1.0 TSI 116PS) back to the dealer. This will probably make updates of the control units. My main problem is that after a few days the car will not go online in the underground garage (without reception) after the exit, but only after the reboot and engine start. This is reproducible. But what is not reproducible, and that’s what my question is about: In addition, I get to Fe – 2x after starting and a few meters drive “return camera not available” => directly tested, nevertheless works. – Last night for the first time, after the narrow exit from a public underground garage, “Lane Assist not available” with warning tone and yellow triangle. Short stop (engine continued), error message disappears, Lane Assist works perfectly. Do you also sometimes error messages “just like that” without A I will of course address this in the workshop, but would like to collect some information about it beforehand. LG Sushirunner
