Hi,
My car has a uneven idle sometimes it's on the 1000 mark sometimes it's 2 lines under.
This alternates through the week. Is it something I should be worried about.
 
The car maybe regenerating the DPF, When it is the idle speed will increase. It shouldn't really be regenerating that often though unless there is an issue with the DPF.
