All owners and people who want to buy a Q8 should definitely open a case and push Audi for a fix. (As well as those who share the road with these cars)

I too was a potential buyer and had a very hared time opening a case. I ended up getting one opened in April of this year after driving and finding an issue. Calling Audi an being sent to drive a different car, and getting the dealer service manager involved. Evidentially Audi does not give as much credibility the customers commentary as much as the dealer service personnel.

I have not heard back since.

I told them I wont buy the car until there is a fix I see on a test drive. They did not seem overly concerned although I did get a thank you

Obviously Audi is aware of the issue. There's no question about it. But do I think it's going to be resolved in time for the release of 2020 model as the rep from earlier this week told me? Nope.

But I would continue to encourage owners AND, more importantly, potential owners to express their concerns with Audi. Presumably more resources will be devoted to a fix if there is established a clear connection between this issue and a dip in sales.

Try pulling back on the gear selector to put into S mode and do the same sort of rolling stop and see what gear you are in.
It dropped to 2.

Not at all, I don't mind helping others. But its mostly selfish, I want one too

And of course, I don't want anyone to get hurt.

BTW-can someone tell me how to stop emails from generating to my email each time there is a new post to thus thread-Thanks

That is an improvement, and can I assume the acceleration was much better? I'm guessing it will not drop down to 1st until you come to a complete stop or use paddles to force it into 1st.

Default Lag throttle issue q8

When coming to a rolling or almost complete stop , auto start/stop will kick in, then if I go to turn/accelerate there is a up to 3 or 4 second lag between pressing on the accelerator and ANY throttle response. It is scary at times when pulling onto a street and the car will not respond after a few seconds. I can put pedal to the metal and nothing happens.

As soon as the break is released the engine comes on, that isn't the issue.

The dealer just called me and was able to replicate the issue on my car, AND a brand new Q8 they had on the lot. This tells me it is an issue with the ECU/system in probably all the new Q8/A8/A7s that apparently all have a completely new Stop/Start system; Not just my car.

It is a bit scary and if they don't have a fix for it, it'd be nice for others with this issue to contact their dealer etc. and make corporate realize its an issue.... or you guys can just tell me you haven't had this issue and I am alone on this : )

I have exactly same issue with my q8. Only just started with lag throttle....I'm at about 3k miles. Happens mainly at a roundabout...slowing down butvready to pull away and theres nothing. Like young.say scary when a cars coming towards you.... I do not use automatic start stop so dont think its connected to that. Like you say seems to be an ecu issue. Taking mine to dealer this week. Will.submit this forum too. Hopefully it can be fixed. Agree with another user that having it in sport mode helps

Wow! I JUST had this happen to me today when I was pulling up behind a car to park. I decided to pull up a bit more, there was a lag, the car lurched forward and I rammed into the back end of the car ahead of me that was parked. Scared the hell out of me and my passengers and damaged both cars. This isn’t the first time I have experienced this throttle lag, and it has bothered me in the past, but now I’ve got two vehicles to fix over it. I believe it could be super dangerous when turning left (us driving) at an intersection, or hitting the gas to avoid some sort of other collision. Would love some input on how to fix this........

On my Jaguar forum, whenever someone would, as their first post, describe some sort of catastrophe incident that occurred with the car relating to a "hot," much discussed issue with the car, it was presumed that the post wasn't legit. And there were plenty of them - employees of competing brands, bots, etc.

Thanks for the info OldSchool24. I’m not a bot and I dearly love my Q! The accident was certainly not catastrophic. Could have been under other circumstances, but was not in mine. No one was hurt. Both cars drove after accident, but I must say I was getting some strange computer things happening today! (Blind spot object warnings with nothing in blind spot, low tire pressure when tires were fine). Hoping it’s not seriously damaged while looking minimally damaged! I must admit, driving home today, left hand turns and pulling into traffic from a stop or near stop made me nervous......
