Air Matic Suspension: Though less common on E350 than higher trims, air suspension components can degrade over time (leaks, compressor failure). Balance Shaft Gear M272: In earlier M272 engines (pre-facelift), the plastic balance shaft gear was prone to wear, causing rough running. This issue was largely rectified by 2007/2008, but worth noting. Ignition Coils Spark Plugs: Routine replacement as per maintenance schedule, but can be a source of misfires if neglected.
