Why does MB mandate service @ dealership?
Recently discovered that valve #4 is bad; not parts within valve, yet port itself, vehicle only has 100K on it. Contacted MB with diagnosis and they are telling me the vehicle MUST be taken to a MB dealership for diagnosis before they will assist me. Curious to know WHY the vehicle has to be checked by a mechanic at a MB dealership service center? Don't they trust the diagnosis from a MB Certified shop/mechanic?

Thank you for your lack of insight! I did have the vehicle checked by a MB certified mechanic at his shop as stated. The mechanic told me the problem was due to faulty manufacturing, therefore I contacted MB USA to be compensated for bad engineering, a bad valve bore. MB USA "mandates" the vehicle be taken to a MB dealership for yet another diagnosis. So again the question is, "Why do I have to have a second diagnosis by ONLY a service tech at a dealership?" Doesn't MB recognize a MB Certified Shop diagnosis?

It's their money. They want to know why they are spending it. What would you do if your owned MB? Just go ahead and do whatever some flunky backyard has-been says?
