Good day
i have a ? i have a 2007 s 550 about 10000 miles. noticed that the suspension has become squeaky, creaky. changing for sport to comfort does little, when the body raises this helps slightly. does anyone have any advice, trouble shooting etc. still under warrenty i had a horrible expereince at the dealership, last time they changed my oil, they unhooked my radiator hose, i think they wanted the 20-25k motor repair work. some help would be super cheers
