Economy files show no new power figure because they are written for torque and drivability rather than peak output.

Remapping the 180 CDI (2009 < ...)

The Mercedes A W169 2004 to 2012 180 CDI (2009 < ...) runs a factory calibration built to cope with poor fuel, skipped servicing and hot countries. We rewrite the fuelling, boost and timing for this engine on this car, then test it before you get it back. The original file is kept, so it can go back to standard whenever you want.

Diesels like this one gain most through the middle of the rev range, which is where you actually drive. It pulls from lower down, holds a gear on a hill, and needs fewer downshifts to overtake. Drive it the same way afterwards and the economy usually improves a little.

Figures on this page are for a standard car in good health. We read the fault codes and check the basics first, and if something needs attention we will tell you before we write anything. Have a look at the other engines on the W169 2004 to 2012, the full A range, or everything we do for Mercedes.
