Air Ride Compressor

5 Mar 2020 •
I have an 05 E55 Amg and my compressor is running more than before. I will pull out of the garage and it runs. Get to the bottom of the drive and enter the street which is a slight difference in height it runs again. I hear if also during drives. The weird part is the sits most of the winter and doesn't go down in ride height. After about 4 weeks I have to start the car and allow it to fill. Then it good for weeks.   My thought is because the compressor is running so often it is on the way out?? And thoughts on this?

Where's the power steering pump on my car

10 Dec 2019 •
Lately I've been hearing a slight sound whenever I am turning the steering wheel after backing out of my driveway. It is not a loud, nor a constant noise but I'm sure it's the steering. So went out and bought some power steering fluid but when I opened the hood to add the fluid, I could not find a container to fill. So thinking that I may just be ignorant of where one may be located in my vehicle I googled it but that did not help.

Starter replacement

I have a 2011 Mercedes E550 coupe. Just installed a new battery and new starter. My husband did the install. Went to start it and loud grinding sound was all I got. Husband said he put the bolts on too tight.. Is that sound an indication of this or possibly something else? 

Media Interface DC power

I have a 2012 E350.  I use an Ipod Touch 6th Generation connected to the Media Interface in the arm rest.  It works great.  When the car is "on", DC power is supplied to the Ipod from the car.  When the car is off, however, there is no DC power from the car to the Ipod and the Ipod continues to run on it's own internal battery and eventually the battery is exhausted.  (I'm not driving so much any more.)
