I've been suffering very similar symptoms in my 55 plate gti dsg
It's on 41k now, so today it's been in Vw Swindon for a dsg oil and filter change
I've not noticed a massive improvement, so does anyone know if they reset the dsg in these £170 fixed price services as a reset, if it does as described above, might be the key to getting it to run smoothly again ?
Cheers
Graeme
