Ferrari Mailing List: Re: Mondial owners - electro-technical question

[Paul Bennett (pbennett]

My wife's Mercedes yellow oil level sensor light comes on quite 
often.  It is supposed to indicate oil level but is only accurate on 
fresh clean oil.   But with a 140k mile engine, and the oil has 
carboned up a bit, it becomes an intermittant nuisance regardless
of level.   

I deduce clean to be a major factor because when I have the oil 
changed, the light stays off for several months and level is still 
near full, it becomes intermittant again.   When I add  oil myself 
between changes topping it off, the light will stay off only for a few 
weeks and become intermittant although stick level is still almost full. 

I've not paid attention to how quickly the Ferrari oil carbons up,
but chances are it could be made to work reliably at least until 
you add the first oil after a change.  Worth fooling with.
