Which sensors may cause "Egress Warner not available" error?

[agurkas]

I get an "Egress Warner not available" warning every time I start the car. However, the lane change sensors seem to be fine, and while parking, everything is fine, too. Trying to see if I can figure this out myself before I have to carve out several hours of my busy days to go to the dealer.

I had vinyl wrap done at a place that I know has done a bunch of them, including for Porsche itself (you likely have seen some of their work in Christophorus PCA mag). So, it's a reputable joint. They said previous clients had some sensor errors but those usually went away withing half hour of driving. I still have the error after several hours on the road.

UPDATE: cleared all the codes with that popular OBDII iOS app and $20 wireless dongle. Looks like while wrapping they don't disconnect the battery, which then causes like a hundred errors.

The sensors are the same as lane change assist uses – and are roughly on the rear quarters behind the body panels.

(can't find a Taycan specific image)

There is a thread with details on which sensors do what https://www.taycanforum.com/forum/threads/egress-warner.7271/post-124055

In my case, all the sensors were working fine since every function I tested worked. Issue was that pile of errors sitting in ECU memory was causing error above on the dashboard. Once cleared - error went away.

I don't have a wrap on my car, so this rules it out for me at least. I got home last night with no egress warner light, but when I got in the car this morning it was on. Only thing I did was open my trunk to put my work bag in and that's it. Drove 45 mins to work and the light is still on. I'm confused. I called the dealer and they said I might need a software upgrade, which needs to be done there.

ODBII BT or wifi dongle is like $25 on Amazon. App is free (or $7). Read the codes and you will know what is likely an issue. At least you show up more educated at the dealer.

Thank you! I brought my car into the dealer and waiting for them to update teh software, which apparantely takes a day to do. For the OBD on amazon, I'm seeing a pretty wide range of readers from $8 - $99. Is there a particular one I should pick up? Thank you.
