Yeah, maybe I shouldn't have mentioned cold starts in my last post. The disa wasn't the cause nor did it solve that particular issue for me. It did however solve the stalling at low speeds. Your initial comment about the clutch control is what made me think that you have exactly the same problem I had cause I bloody well knew it wasn't my clutch control that was causing it even though there were no codes. Anyway, well worth checking, quick and easy unlike those bloody vanos seals..
