Frequently Asked Questions
Does this manual cover both the CLA 45 and the higher-output CLA 45 S?
Yes. Both variants are fully documented — the standard AMG CLA 45 4Matic+ (387 hp) and the CLA 45 S 4Matic+ (416 hp). All engine maps, torque specifications, and performance-specific procedures apply to each tune level, including differences in exhaust valve control and boost pressure settings.
Which chassis codes are included — C118 or X118?
Both. The C118 platform underpins the four-door CLA 45 sedan, while the X118 is the Shooting Brake wagon body sold in select markets. This software covers complete service procedures for both body styles under the same 2019–2022 production window.
Are AMG-specific systems like the performance exhaust and drive modes covered?
Absolutely. The software includes full documentation for the AMG exhaust valve actuation system, AMG Dynamic Plus drive mode electronics, MBUX infotainment integration, and all driver assistance modules. Wiring schematics include connector pinouts and ground point locations specific to AMG-variant hardware.
