Hi I've had my 2010 Clubman S with 35k miles (with JCW tuning kit) for about a year now. I've noticed that after I drive some where and stop and start up the car again, it has a hard start. It takes a few seconds to turn over. It only happens when I've driven the car. Cold starts are fine. Fires right up. A tune up a few weeks ago didn't change anything. (changed spark plugs and had the charging system tested, came back ok)
Any idea whats causing this? I also noticed mileage down slightly. Was getting 28-29 now around 26.


thanks

 

Is your check engine light on or are there any fault codes present in the system?

 

no check engine or anything. Other than this thing with the warm/hot hard start it runs fine.
