Delayed accelerator response

I had a 2009 2.7 Diesel A5 for 10 years. It was buttery smooth, loved it. In Jan 2020 I sold it and bought a 6 month old A5 Petrol 40 (1996cc). I bought it because I really enjoyed driving the A5 and I like to go on tours. However, this car is NOT a joy to drive. In important situations like entering a roundabout or at busy junctions, there's a 2 to 5 second delay in the accelerator response, and then it takes off like a rocket. I consider it verging on dangerous.

It's also jerky on normal to hard acceleration from slow speed. It's like a learner driver missing the clutch.

I'm about to put it in the hands of my local Audi dealership who will charge me £120/hr to diagnose the issue. Has anyone else come across this and what are the likely causes? Would it be something covered by warranty? Just trying to get a heads up before I take the plunge with the dealership.

Thanks for that Alex. What a crap thing to do from Audi though. I just want rid of it now. My next car will be fully electric and very prob not Audi because of this. Who wants to coast into a roundabout effectively not under control, be late matching the speed of the car in front or all the other things this affects. If a huge company can make such a crap decision then they can't be trusted IMHO.

Alex is right about the car learning your driving style. And if it’s used, and is already adapted to the previous owner, this can take some time.
Had my last two from new, and they were loads better. And the petrol engine seems much better than the diesel for throttle response (for me at least).
One thing I learned to do, and still do, is flick it into S mode for those r/b’s and junctions where you need to be really nippy.

I'd be curious to know how the gearbox "learns" my driving style. What is it sensing, storing and changing the output of?

I've taken to micro-kickdowns on nearly all accelerator movements where I need to be nippy. It seems to jog the thing into moving.
So, put the car into my local Independent Audi/VW shop and they thought it drove ok but found a logged fault: "Intake Manifold Flap Position Sensor (Bank 1) P2015 00 (096) - Implausible Signal Intermittent". They didn't clear it on purpose. Put the car into my local Audi dealer and they sent me a lovely video of their safety inspection! They also applied a firmware update to the EMS. This has tightened the response at the low speed end. But it still does some weird shit on motorways. At 60 MPH, a gentle accel can result in 6K RPM scream for a couple of seconds, (with attendant loss of accel) then it drops itself into a lowish gear before it settles back to D6 or 7. Not nice when filtering onto an MWay. Most of the time a gentle accel does nothing for a several seconds then give an instant kick up the backside. If Audi think this is a good driving experience, I'm off Audi's for good. I'm going to have to go back to Audi again I think.
