Thanks steve, The car is 2009 with 84,000 miles. Says it has lots of history with it, and apart from possibly doing the spark plugs, I dont think the seller has done much as it was a px for them. and they cant throw any more money at it, so i got it a bit cheaper. it hasnt been driven for nearly a year as its been sat in their yard as its the lower end of cars they usually deal with. But the issue was present before it sat for a year, Maybe best is to report here the fault codes in a day or so once done, and go from there. The carbon clean is being done on thurs, so i will know more after that Thanks for the reply tho

Hi all. I have just bought an s5 that was sold as lumpy on cold start, But once warm its fine. It arrives tomorrow , but have seen many video's from the owner on start up and idle etc once warm. I plan to do a carbon clean on it. and as far as i know its had the plugs done. But i cannot verify this. I have seen a video where its rough on starting, very rough lol. spluttering and misfires But after 2 - 5 mins its ok. But still slightly spluttery as it hasnt been used in a while. No smoke or anything from the exhaust / engine If the carbon clean dosnt solve this issue. What would be any ones next point of action please. The carbon guy will be reading the codes etc tomorrow , may have a better idea then. But seeing as it gets better once warm, I wondered if anyone might know what that might points to or suggest. Many thanks in advance. Mark
