Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Rust on Sills and Wheel Arches W202 strongly prone to through-rusting at sills, wheel arches and door lower edges. Absence of factory sealant up to 1997 accelerates corrosion. Strut top rust is safety-critical. Symptoms: Blistering under sills, visible rust on wheel arches, porous underbody, through-rusting at door lower edges from 150,000 km | High | |
| Rust on door edges and sills Rust on door edges, sills, wheel arches and under door seals. A faulty primer-bath process encouraged early rust formation. First build years particularly affected. Symptoms: Rust bubbles on door edges, brown discolouration under rubber seals, visible rust-through on sills from 120,000 km | High |
