Vehicle Weaknesses

WeaknessCost
ABC suspension valve block defective

The ABC hydraulic suspension on the C215 is the most expensive weak point. Each axle has a valve block (approximately €1,000 without fitting). Contaminated hydraulic oil damages the proportional valves.

Symptoms: Vehicle drops after parking, uneven ride height, ABC warning message, pump noise
from 100,000 km
High
ABC Suspension: Valve Block Wear

The two valve blocks of the ABC suspension wear through hydraulic contamination. Once the vehicle immediately sags after being switched off, the valve block is defective. Delayed intervention leads to pump and line damage.

Symptoms: Vehicle sinks noticeably immediately after switching off; one-sided sagging front or rear; hydraulic oil leaks under vehicle
from 100,000 km
High
