I know of an M-B dealer (not naming names or being specific) that would constantly recharge at no cost a malfuntioning A/C on a friends car always saying that she used her A/C too much.

Inmediantly after the warranty runned out, the next time she took the car to be recharged, they slapped her with a US$3,000 bill for a broken evap.

It is obvious that your dealer is trying to hide something major and just buying time so they can later shoot you with a major repair bill.

I will definitely take the car to another dealer and if nothing happens, I will pay for a test at a good independet shop and then go back to Mercedes.
