Audi S3 2019 Sportback 5Dr (Stock)
40k miles.
Hi all, have been having this issue with my car for a few months now.
Seems to hesitate when flooring it at 2,800/3000 rpm + and when in 3rd gear onwards.
Initially thought Spark plugs may do the trick. This was recently changed - and on the same day my brother in law had connected his diagnostic kit - it came up with a fault code re o2 sensor bank 1 sensor 2.. he had cleared that for the time being and taking it to two garages (including 1 VW/Audi Specialist), we haven’t been able to replicate the fault code and the specialist couldn’t insist more that it’s not the o2 sensor and that could have flagged up even from a bad batch of fuel.
They recommended I take it somewhere with a dyno system which may help to identify the issue?
I’m so lost as to where to go from here. My brother in law who are somewhat better clued up on mechanics than me are now suggesting changing the coil pack. Last full service was March 2022. Minor service 2023. Both from main dealer. We do do ALOT of miles.
Any suggestions?
Thanks in advance
