Agreed about the Xenons staying on too long. I also had a situation the other night when it was raining fairly hard and the auto wipers weren't activating. Other minor niggles are:
1) Intermittent squeak from drivers door now and again - I don't know if its something to do with the rubber seals
2) Not a niggle but a potential problem - the doors do hold at a certain opening point but its not big enough to get out. Therefore if you open it a bit further and let go it just swings open. You have to keep reminding passengers (i.e. the Mrs) not to let go of the door. I can see that dreaded moment when it swings open and smacks a wall

3) Lots of stale muddy water being caught on the boot sill, i.e. runs of the roof and just sits on the back sill. It then subsequently drys and your left with a filthy looking rear end

4) The carbon fibre effect being a pain in the arse to keep clean
5) Again not a niggle but a nuisance. When your on the sat nav screen on the MDF and you want to change radio stations, when you change, it doesn't tell you what station your now on. The only way of checking is coming out of the nav function and into radio
