Problem overview

Some Audi TT owners report experiencing issues with windows not closing properly, which may be linked to a malfunctioning comfort control module. Additionally, some owners find they are unable to lock or unlock their doors using the internal button or remote key fob, a problem that could also stem from the same module. Concerns with the alarm system not functioning correctly have been reported, potentially tied to comfort control module failures. Furthermore, difficulties with the gas tank lid not releasing properly and problems with the convertible top, such as it not operating smoothly or making unusual sounds, might indicate issues with this module as well. It is recommended for owners facing these symptoms to consult with an expert familiar with Audi TT comfort control module diagnostics to identify and resolve these problems effectively.
