I was driving into work in my rapid space a k 2015 diesel SE tech today engine warning light came on and when I stopped the car there was a small amount of smoke which quickly stopped coming from the grille. A small amount of what looks like oil was on the ground after. Looked under the bonnet and can’t see any leaks etc wondered if this was a common issue? And what it’s likely cause is? Hope someone can help AL
