Then find a better service shop. There is no reason to take the van to a dealer for service.
If you are going to diagnose your problem and then tell the dealer what to repair, don’t. They will do exactly as you say and it will likely not fix the problem. A good mechanic will take time to diagnose the problem (at a cost to you for diagnostics) so he knows what is wrong rather than guessing.
