Version Coding

WARNING: This page is about a different car, the 1999 Mercedes-Benz C230. However, it is still accessible from the selected car via links, so may be relevant.

Version coding allows different settings to be programmed within A/C push-button control unit. Engine version is automatically transferred from the instrument cluster to the A/C push-button control unit by the serial interface (K1). All other version coding is done using Hand-Held Tester (HHT). When performing version coding follow HHT screen prompts and select desired settings. See A/C PUSH-BUTTON CONTROL UNIT VERSION CODING  table.
