I did ask a straight question: where is the fuse. Your unsolicited opinion wasn't necessary and you still didn't answer the question.Not to be a downer but:
Our Diesel engines are designed to run on Diesel fuel. Running any other is sub-optimal and is the road to trouble, expense and heartbreak. One could get away with it on older, simpler Diesels such as the Mercedes W123 but not today's overcomplicated engines such as yours.
olive oil is a helluva lot more expensive than Diesel fuel.
