I believe the ---h in the hidden diagnostic menu indicates there is a fault with the engine's oil level sensor. It maybe that one fault was registered one time, or it could be completely faulty. Best to manually check the oil to make sure the level is ok.
thanks for your answer, I ckeck the oil & its level.. All Ok!!
some times "Serv" glows & some times it turns off !! why?
the mechanical technician ckecked the oil & its level & says all ok, & the tablo indicates that oil level is good "ooooo" & "oil ok"
