l overfilled my Disco 4 with oil, I stopped next to the road after it started to self drive. I tried to burn the excess oil by accelerating while in neutral. I then couldn’t stop the acceleration until it cut itself off. There was smoke all over coming out of the exhaust pipes. It is now not switching on am not sure if the engine is ceased.

Can someone tell me what could be the problem and how do I fix it?

 

What was the outcome of your landrover situation? Did you get a flashing oil light before you realized there was too much oil?
