I have a 2006 C2S with about 44xxx miles on it. Its kinda a garage queen (10K miles in the 4+ years I've had it).

About a week ago I started to get a countdown to servicing when I started the car. It started at "28 day until service" and obviously goes down every day.

I drive enough to change the oil once a year and that isn't due until August or and that should be based on miles, not time.

Can anyone explain the countdown. I'm not seeing anything int he manual.

 

I believe it's a count down from the last annual service.

 

I don't understand that either. mine started that some time back as the car approached 40k miles. I doesn't give "days until service" any more, just says service is due or something to that effect. I change my own oil every 5K miles so I just ignore it.
My wife also has a '15 macan we bought with 10,800 miles on it. I went ahead and changed the oil just for peace of mind and now at 14K I am getting the same message on it. Owner's manual is real vague for service intervals so I am ignoring it also. I will change at 5K on it too. Oil is a lot cheaper than an engine...and doing it yourself is a lot cheaper than dealer will charge.
