From what I've read, that could be a big selling point for the box!

Maybe for some, but the big error displayed is annoying.

I don't have a need to turn off auto start/stop. I run in dynamic/S all the time so it is disabled anyhow. (But the error still shows up in that mode with the box as well)

Which tune did you get? Also what fault are you getting?

Auto start stop malfunction and https://www.audiworld.com/forums/a4-b9-platform-discussion-212/automatic-start-stop-function-malfunction-2909635/#post24882580

I guess I'm confused. Are you getting the fault every time you drive the car, the whole time even after a restart with the tune in? Or is it sporadic? I get it occasionally but I wouldn't be able to attribute it to the tune since the majority of the time it's always working with the tune attached.

Fault comes on every time the car is driven and the box is installed.

As soon as the start/stop malfunction is shown I can scan with Vcds and the manifold sensor fault will be stored. Reset it and it will come back same time as the start/stop malf. Reset it again in Vcds, remove the box, install jumper, no malf or faults.

I didn't want it to be the box, but it is unfortunately.

If you have Vcds you should check the ecu faults, you probably have the manifold sender fault stored as well.

I have had the fault but it's a hidden fault, nothing that triggers a cel. Also I get the actual start/stop malfunction very infrequently, maybe 4 times in the past 2k miles with the chip in. Something must be up with your box that you get the malfunction every time you drive the car.

I've never had the message the OP posted, but auto stop/start isn't working like it did when I first got the car. At first it was always on when I started the car and I'd have to push the button to turn it off. Somewhere along the way it stopped coming on automatically and instead on the screen behind the steering wheel there's the A symbol with a circle around it. Unless someone posts what that icon means and what's going on guess I'll have to resort to the manual.

Which one are you using? I installed the Racechip the other day. I did get the error one time but it's been fine every since.

Just curious as to how many people with the Racechip have gotten the error message atleast once (seems like there are quite a few) compared to people without the box. And also, whether the message stays on the dashboard or goes after a while or goes on restarting the car. I haven't installed the Racechip yet and I prefer everything in my car to work perfectly, without any error messages if possible. It's like wanting to have your cake and eat it too.
