Mercedes-Benz S500 Problems

Active Body Control System Can Leak Hydraulic Fluid

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

Oil Seepage on Back of the Cylinder Heads

The Mercedes Benz S500 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.

Closing Assist/Door Lock Issues Due to Pneumatic System Problems

Problems with the pneumatic system can cause closing assist and door lock issues.

Mercedes-Benz S500 Reviews

Mercedes Benz automobiles are a real joke. I have two of them and they are always in the shop. Great for the mechanics but not the owners.

If you add up the covered and uncovered costs for repairs on my 2000, S-500, it would be well over $25,000. IMH, Mercedes Benz over engin...
