I have had my RS5 for 6 weeks now. It is a new build so it's the model Audi call F5 and this forum is calling the B9.
I have been trying to code the stop/start system to be off when I start the car but without any success so far. I have tried a device called ODBeleven, it's a cheap device and a free app but you soon find out you have to buy credits every time you use it so it gives me the feeling it's a bit shady, and it hasn't worked so far but that might be me losing confidence in it.

Has anyone managed to code a 2018 RS5?

I didn't think the RS5 had the stop/start system, at least in the US. Photo's do not show the "off" button as on A5 and S5.

OBD11 is not a shady app, if you cared to do a search you will see plenty of us have made a bunch of usefulchanges to our cars just fine with OBD11. You don't have to buy credits, you can do manual coding for almost all the changes if you just take the time.

I checked the interior photos on the Audi USA website and I think your right, the stop start button is missing (along with a few others).
That's a good thing for you guys as stop start is annoying.

Thanks for the reply.

I'm confused - if you've had your RS5 for 6 weeks, and it doesn't have auto stop/start, what made you want to try to code it off?

I'm guessing his UK version has the start stop??

While the start / stop can be defeated with OBD 11 it's not the easiest of mods and may or may not have some side effects. If you do some actual research on it, you will find there were numerous attempts that didn't work, and I believe the "final solution" involves (at a minimum) changing an AC parameter to fool the car that the AC is on all the time.

If you were easily confused about credits and whatnot with the ODB 11, I'm thinking this is not a change you're ready to make.

Ah, I missed that nuance. Thanks for clarifying. There were a number of articles last year (such as this) about the RS5 having a *better* stop/start system, so it seemed weird that the folks taking delivery reported that it didn't have it at all. Maybe it only made it into non-NA models.

In the ROW the RS models have start/stop, but US-spec models thankfully omit this useless feature. I hope it stays that way.

Good information. For anyone who has an RS5 with stop/start who has also driven an S4/S5, is there any noticeable difference in start/stop behavior? Just curious if Audi went ahead with their plans to use a more advanced system.
