Unfortunately I know very little about cars. I can't help but think now that I should not have bothered to take it to Audi.
You say I should drive carefully but at the moment the light is on all the time, the fan seems to stay on for longer than it should and I swear the fumes are worse (smell is stronger) than prior to what ever they did during the update process. Perhaps I'm just being paranoid but if this is the start of something going wrong, what problems or signs should I be expecting or should I look out for, particularly if my car could be dangerous to drive?
Thanks
