Any problem with the hydraulic system in this car

I believe Mercedes uses silicone rubber for it's hoses, practially indestuctable....most use a butyl lined rubber, go cracky after ten years...you might put a glove on and check how flexible they are, then replace them~

CL55 AMG 2003 model is a very good and reliable car model, however, as you have mentioned that you are using this car from past 10 years, so I will suggest you to take your car to the mechanic and ask their suggestion on the same. He will check your car and then will suggest you the necessary corrective measures. You can also have a look on the various tips and suggestions posted by experts online. Like I regularly read http://www.automotix.net/info.html to know about the various aspects of my car.

the main risk with the suspension and power steering is the flexible hydraulic lines between the tops of the struts to the solid sections on the subframe and the PAS/suspension pump wears out but better to save money and only replace when they actually go because the pumps are very expensive!

Yes I have a 2003 sl55 and my car was just dead so i checked front battery and it's 100% and the back is 75% and even the key has new batteries in it,,, not sure what to do know?. Please any help would be appreciated!!!
