The W169 launched with a much more refined design than the W168, but early cars suffered from door seal rust due to a faulty weld process and exposed radiator/condenser units prone to stone damage. CVT gearbox problems were also common from the start.
The 2005 period has 2 more issues than the Mercedes-Benz A-Class (W169) average across all year periods.
Automatic W169s can suffer worn clutch actuators or CVT issues.
Most affected: CVT-equipped models
Petrol M266 engines can suffer from timing chain stretch and tensioner failure, leading to a rattling noise on cold start. If left unchecked, the chain can jump and cause catastrophic engine damage.
Most affected: A 150, A 170, A 200
Diesel CDI models can develop leaking injector seals, leading to the "black death" — a build-up of carbon and fuel residue around the injectors that can damage wiring and the cylinder head.
Most affected: A 160 CDI, A 180 CDI, A 200 CDI
