A few weeks ago my 1.2 16v Clio went into a Renault dealer with 3 problems, not starting, trip computer resetting itself and a white discharge in the top of the oil filler cap.
A month later and pestering them every day we finally got the car back, starting problem has gone, but checking the oil filler cap the white discharge still appears. Theres none and the dipstick and there never has been, it does raise the question as to whether theyve changed the gasket at all or if this white discharge is normal of a car that spends its time outside and in the week only doing fairly small trips to and from work (9 mile round trip).
Does anyone else get this build up?
