I want to change the light assembly it was busted somehow!

Te engine light is on. One shop said I need to replace MAF censors (two units) while the scanner in the other shop says only left sensor, Component B2/6 Left hot film mass air flow sensor is bad? Are they talking about the same thing? Also, Exhaust gas recirculation control code came on. Is this because the MAF is bad, or it's a separate issue? Someone help me. I spent way too much money in the past year on this car. I can't afford getting ripped off.

I was under the impression there are 3 motor mounts or are there 4 ?

If rear mounts need to be replaced whats the labor hours required to do job ?

The main battery was replaced 3 years ago, could it be the small battery beside it?

Hours after I came home, my car has a loud horn like sound coming from under the hood. Theres a big black ball looking thing on the right hand side close to the dashboard that stops the noise when pressed in. What is this and how do we shut it off?

At startup the display always shows the miles and total mileage used which is fine but I would manually change it to mph settings. I'm used to that settings. My Porsche display was changed to that setting and I don't have to change it every time I start my car. With the Mercedes, I have to change it every morning. Is there a way to change it and keep it at that setting?
