Has anyone experienced , or does anyone know what might be the cause of, this? I have an 2003 A4 2.4 petrol V6, the 170ps version, with a multitronic box. I used to think the multi suffered from a slight judder when taking off from a standstill, but have now realised it's not the box at all, it's the engine. What I'm experiencing is what feels like a slight misfire or throttle hesitation round about the 1800 rpm mark, the speed at which the multitronic initially holds the engine for a normal to brisk step off. It's only fleeting (certainly gone by 2000 rpm when accelerating) but if I put it in neutral & feed in just enough throttle to hold the revs around 1800 rpm, it is definitely there. Thoughts, anyone?
