Vehicle
Mercedes-Benz A-Class
The compact hatch and sedan; front-driven, Renault-derived diesels in some versions — worth knowing when a code's community wisdom seems to come from an unexpected brand.
Generations
-
W169 2004–2012
The tall sandwich-floor layout; a CVT on many, which reads nothing like a torque-converter automatic.

Service information
Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
