Oh, Also if you don't have an MBCNA membership, get one, it will save you tons on repairs and diagnostics, most dealerships give members a very sizable discount, I have saved thousands, the parts at the dealer are cheaper than if I were to buy them at autozone or pepboys, and they are usually in stock. And they are MB parts! Also the discount allows me to use the dealership for what a good indie shop would cost.
