I would be tackling MB Head Office on this because an external sensor should be sealed against moisture ingress and they are obviously not fit for purpose. They should at least contribute something. Also I would be taking them to task as to why it required 3 diagnostic sessions to determine that the sensors were faulty - is there a competency issue with the dealer that you ended up paying for?
One option I have used in the past very successfully is to go into the dealer showroom on a Saturday morning with invoice in hand, when it is nice and busy with prospective buyers and explain the situation to a salesman, pointing out how disappointed you are with your Mercedes and the service you have received from such a prestigious marque - all done with a loud and clear voice.
