Just got back off holidays and the last couple of nights i've been out in the S3 I can't help but feel its slowed down a tad. I filled it up before I went away so it does have a full tank of fuel but overtaking people it just feels a bit slower than I remember. Is there anything obvious to check, it drives fine, no lights on, no missfires or anything. Might just be me imagining things but thought i'd see if it could be anything obvious. Its completely standard engine wise if it makes any difference.
