Any help or advice would appreciated, Problem started with engine turning over but refusing to start. On checking vehicle engine oil was found to be low which in its self is unusual as oil is regularily checked and does not use any. topped oil up and left overnight. On checking next morning started immediately and ran normally. Within a few days engine block warning light started flashing along with an intermittant loss of power and once again engine oil found to be low. there are no signs of leaking oil, This is on a 2003 Freelander td4 Diesel. Any advice gratefully received, Thankyou
