A VAG (VW/Audi/SEAT/Skoda) fault code indicating a fault on the CAN data bus that links the comfort-system control modules (door modules, central convenience/comfort control module, etc.). It is commonly stored as "no signal/no communication" or as "single-wire operation," meaning the two-wire CAN bus has dropped to running on one wire, causing degraded or lost comfort functions such as windows, central locking, and related features. Typical repair costs on Audi range from $250 to $900, depending on the specific model and root cause.

- Instrument Cluster Pixel Failure and Intermittent Gauge/Warning Display Loss2000-2006
First-generation Audi TT models commonly develop failures in the instrument cluster LCD/pixel display and, in some cases, intermittent gauge or warning-light operation. Owners report missing center-display information, unreadable driver warnings, and occasional erratic cluster behavior caused by internal solder joint or display ribbon failures. This is well documented across owner forums and complaint databases for Mk1 TT and related Volkswagen/Audi platform cars using similar clusters.
