The final production year before the W169 replaced it. Late cars benefited from all accumulated fixes but age-related rust and gearbox issues remain the primary concerns. At these prices, economics often favour scrapping over major repairs.
The 2004 period has 3 more issues than the Mercedes-Benz A-Class (W168) average across all year periods.
Older W168s can corrode around the rear axle mounts and floor seams badly.
The CVT and semi-automatic Sequentronic gearboxes can suffer from wear to the variator, clutch packs and mechatronic units. Repairs are often uneconomical on higher-mileage cars.
Most affected: A 140 CVT, A 160 CVT, A 190 Sequentronic
Blocked sunroof drains and degraded door seals allow water into the cabin, which can corrode underfloor electronics and wiring connectors, causing random warning lights and intermittent faults.
