2011 Mercedes-Benz E550 4MATIC Problems

Squeaking/Worn Brake Pads May Require Rotor Replacement Also

Due to the size and material used on the brakes of these vehicles, the brakes may start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).

Oil Seepage on Back of the Cylinder Heads

The Mercedes Benz E550 4Matic may have engine oil seeping or leaking from the back of the cylinder heads. This is commonly misdiagnosed as leaking valve covers.

On the back of the cylinder heads there are three, in total, plastic expansion plugs that plug access ports to the camshafts. These plugs are well known for seeping oil, and leaking if left unattended. The oil will run down the back of the engine and eventually make it to the ground. 

Replacement of these three plastic plugs is extremely simple, and should be done as regular maintenance. The recommended interval for replacement is every 60,000 miles.

Endured the E550W Class Brake Pad and Rotor issue. Found a blog posting that noted an improved/corrective break pad. Passed the information on to my service representative. One good note, the dealer in Virginia Beach installed the new pads at no cost to me. The brake problem never repeated since. Sadly, MB was not the source of the correction, even after several attempts to resolve the iss...
Since purchasing new in July 2011, I have had replaced under warranty the air shocks, front struts and, as soon as the parts arrive from Germany, the interior wood trim. In addition, I have had to replace the brakes/rotors at ~29,000 miles. Shame, really, because other than the suspension and brake issues, I really like the car. The engine is terrific - exactly what a normally aspirated V8 s...
