Error messages appeared on my dashboard concerning the braking system (anti-lock brake system [ABS] and brake assisted stopping [BAS]), when I drove the car the next day. I made an appointment with "Your Mechanic" to remedy this problem and some one is coming tomorrow.

Shaun did an excellent job! I needed an 80k miles maintenance service and since the service was expensive, I wanted to just get an oil change and get his opinion on what services were needed within the long list of Mercedes recommended services. I handed him the keys and went back to my office. He finished the service within the allotted time and let me know what services I needed with a detailed report of my fluid levels, etc. All of this and the time needed from me - no more than a couple minutes of handing the key and taking it back after the service. Convenience at its best!

All about Drive Belt Tensioner Replacement

A Drive Belt Tensioner is a pulley mounted to either a spring mechanism or to an adjustable pivot point that is used to keep constant tension on your serpentine belt. That is the big long belt in the front of your engine. The tensioner rides on the outside surface of the belt to put pressure, or tension, on the belt and against the pulleys that drive things like the alternator, power steering, air conditioner, etc.
