Hi, i have also just bought a used Audi A3 1.5 tfsi S tronic,the problem i have is minimal,but it does have a slight pause in power at low speed,almost like the fuel is momentarily cut off & then turned back on.I have another issue with the engine noise whilst ticking over,listening outside the car,i personally think its a bit noisy.Not sure if the COD has something to do with it.I have dropped mine off at Stoke Audi tonight for investigation ,however i was told by the guy that booked me in that if nothing was discovered that i would be liable to pay the diagnostics fee of £156.He told me that the issue with the Kangarooing effect was only on engines post 2019.
