I took my 2012 Range Rover Vogue into the local dealership for its first oil change/service. A week later, the car was losing a significant amount of oil and was taken back to the dealer. I was told that the new oil filter had failed. The filter was replaced, the oil was topped up and the engine bay had been steam cleaned. Two weeks later, after a further steam clean, the smell of burning oil on the cylinder block persists. What would be a reasonable expectation to have this situation put right? It certainly affects my enjoyment of an expensive car. Should I put up with the burning oil smell until the oil deposits are eventually burnt off?
