Some vehicles combine keys and screen in a single front controls/display interface module. Ford calls such a unit FCDIM, for example with the small audio display on the Escape (2013-2016) and the 2016 Transit Connect, Transit and Focus (SSM 47234), while the 2011 Saab 9-5 reserves U0257 for a unit merging info display and faceplate. Audi documents the code itself for the 2026 Q3: the panoramic display (KX2) ignored touches on the central MMI screen, and U025700 was active in information electronics control unit 1 (address 005F). The display's own software was to blame; dealers replace the display, while improved software follows from model year 2027 (TSB 2082126/1). A silent unit leaves both its keys and its screen without function; separate units use U0255 and U0256.

Likely causes

Software fault in the combined display unit (Audi panoramic display)

Unit without power or ground, or connector not fully seated after dashboard work

Internal failure of the combined controls/display unit

Fault on the infotainment bus branch shared with other units

Symptoms

Screen does not respond to touch or stays dark
Radio preset or menu keys without function or erratic
