BMW X5 Engine Problems

The BMW dealer is the best placed to work out what’s causing your problem. If you’re concerned about the potential cost of his work ask for a quote and make a decision based on that. You could place a time limit, of say, three hours on him and ask for a report at the end of that time so you can decide on what you then want to do. Without knowing the cause of the problem before you start it’s hard to say how long the investigation might take.
