How smooth is your Tfsi 252 engine when cold

[mickwillow]

So I’ve brought a ex demo a5 tfsi 252 coupe with 6000 miles on it a few months ago. When the engine’s cold and started it doesn’t seem very smooth on idle tick over, as if it a missing every couple of seconds (feels slightly bumpy)
Anyway I booked it in at Audi for them to investigate and left it overnight so the engine was cold.
But it’s come back with no fault code stored I was thinking it may have been a coil pack breaking down
I don’t used supermarket fuel only shell Vpower ,and it’s drives lovely no problem. So does anyone else have a 252 tfsi and what’s there’s like
Cheers

I have had two of these and the engine is ultra smooth, even when cold. Definitely should not be missing. Get the garage to start up another car and you should see the difference.

Also it’s designed for 95 RON - you’re just wasting your money buying higher octane fuel. https://oppositelock.kinja.com/the-real-impact-of-using-wrong-fuel-octane-1785829176
