Hi Julius, cars are usually sold as is. If the dealer did not give you a written warranty and they are not willing to stand behind the sale you are pretty much on your own. I'd speak to the owner of general manager of the dealership and see if they are willing to at least help you out with the repairs. It is very common to have numerous fault codes stored in any Mercedes if the codes have not been read and erased in a long time. All fault codes should be erased after the initial scan and the car should be driven until the warning lights come on again and then the codes should be read again. You will likely have far fewer codes than the initial scan and the new codes are the ones that you need to address.

Let me know if you have any questions.

Can I clean the codes by disconnect the battery
Expert:  Marty replied 1 year ago.

No, disconnecting the battery will not clear any of the fault codes. The car need to be connected to a Mercedes tester to have all of the fault codes in all of the modules erased.
