Hello,
I have a 24 plate 1.5 tfsi sport Q2 and have the same or very nearly the same experience,I’ve owned the car 5 months and my wife and I have both had this while driving as you say approach to junctions or roundabouts, I thought it was me having changed from an automatic diesel vehicle to an unfamiliar manual petrol and not driving it as I should. But my wife has had the same issue and usually drives her 1.5 tfsi golf , I’m hoping it’s me not quite driving it correctly, deep down I don’t think that is the problem ,If it is the car then it’s a bit worrying- I’ll watch this thread with interest.
best wishes
Mark
