Q&A

Good answer, I guess the question needs to be clearer, I did no work on the vehicle, just brought it in for the recall. Vehicle was running fine, no leaks, etc. They called me when the problem occured doing the recall work. So, would it be my responsibility for paying for the repair or should it be theres?

I cannot speak for the Dealer or Mercedes, and I don't know the details of this repair. If you just received the recall notice and brought it in, then it would seem any other damage from the leaking solenoid should be covered. If you received the notice 6months or a year ago and are now just bringing it in, then they have a reason to try and make you partially responsible for the repair.
If it were me, I would be asking these questions to the service advisor at the dealer, the service manager, general manager, owner and then Mercedes until I got them to pay for this since it is related to the failed part, for which they've already excepted responsibility.
Good Luck and let us know how it works out.
