[colinmk1]

hi, i have a 54 plate clio 1.5 dci, when started from cold it gives a puff of white smoke which is normal and then it clears but after its been running for about 20 mins it then starts giving out white smoke (when warm) there are no warning lights on dash, any ideas? thanks in advance

Best guess is an injector(s) fault

thanks mick, is there any way i can check or would it need going on diagnostics, the car also drives fine with no loss of power

It needs looking at properly and a leak off test carrying out I'm afraid
