Warranty coverage and non-authorized service
I'm looking to buy my first (!!) Mercedes, and it'll be a c63s. One that I am looking at has had all the recommended service performed, by (according to the seller) "a good friend who works at a mercedes dealership".
I'm obviously not thrilled with that answer. They documented what was done, but it's basically scratches in a notebook.
My overall question is how particular are MB dealerships with warranty claims when scheduled maintenance is performed by a non-authorized shop? Maybe in a more general sense - if someone has their car serviced at a Big-O... invalidated warranty?
Appreciate any thoughts or experiences you have! thanks!
The problem with using a third-party shop nowadays is they don't always have access to the systems that are used to update the on-board computers and such and I don't know if the dealership would perform those updates free of charge.
I wouldn't worry about the warranty for basic service like an oil change or brake fluid flush if you are using a shop that you know and trust. It is of paramount importance, however, that they know exactly what parts and specifications to use because if their work does lead to a failure then obviously you are in trouble. You are under no obligation to divulge where prior service was performed.
