Sorry if this question has been answered elsewhere a hundred times before, but if it has then the answer is proving surprisingly elusive in the forum search Does activating extra options invalidate your warranty with Audi? Is it always black and white? Do the service departments see it so often and for such minor things that a warranty would only be invalidated if the fault is directly related to the option you activated? Has anyone got experience of insurance companies getting picky about being notified? The kind of things I'm thinking about getting done are the needle sweep and the auto-dipping kerbside reverse mirror, but I won't risk it if there's chance that Audi would turn away my 1-week old A3 if the engine fails to start just because I've played with some minor things.
