Was wondering if any other 2.2dci owner's have had this problem. My 04 reg is regulary serviced by me an has done this even when nissan done it. Story is it keep's leaking from the oil filter make sure filter is tight move's slightly an only just. Tonight outside the shop see a rainbow effect on the floor thought could be any one's car.....get home see it on the drive. Check under neath my new filter is covered in oil made sure it was tight moved a tiny bit. This filter was replaced in july under warranty ! A neighbour's 2.2dci x trail doea the same thing !
