Hi, I am new to this forum and i am hoping some one out there can maybe help. I have a C-Max 2.0 CDTI zetec 05 reg with 22k on the clock which I purchased from my Ford main dealer in January. I am very happy with the car, however on two occasions over the past couple of months when starting from cold after standing overnight and using no throttle i have noticed an amount of blue smoke from the exhaust. It only happens when cold and disappears after a few seconds, it has only happened on these two occasions all other times there is no trace of smoke. even after being left for two weeks
